Figure 7: EX4600-EM-8F Expansion Module
NOTE: The EX4600-EM-8F is not supported on the QFX5100-24Q running in QFabric systems.
The QFX5100-24Q is configured for the QFX-EM-4Q by default, but any combination of the two modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-8F is inserted instead of the default QFX-EM-4Q, the new configuration causes the interfaces to temporarily go down. Likewise, when an EX4600-EM-8F is running on the QFX5100-24Q and it is swapped with a QFX-EM-4Q, the interfaces temporarily go down, which can cause a short disruption in traffic. · QFX5100-24Q-AA As shown in Figure 8 on page 10, the QFX5100-24Q-AA is a 1 U, top-of-rack, 40-Gigabit Ethernet QSFP+ switch with 24 high-density QSFP+ ports. Each QSFP+ port can be configured to support 40Gigabit Ethernet or as a set of 4 independent 10-Gigabit Ethernet ports. The QFX5100-24Q-AA can also be configured to support twenty-four 40-Gigabit Ethernet interfaces or ninety-six 10-Gigabit Ethernet interfaces using breakout cables (channelization mode) with 1280 Gbps output. The switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies. The QFX5100-24Q switch provides full duplex throughput of 2.56 Tbps. The QFX5100-24Q-AA module bay can accommodate a single Packet Flow Accelerator (PFA) double-wide expansion module (QFX-PFA-4Q) or two single-wide optional expansion modules (two or one each of QFX-EM-4Q and EX4600-EM-8F). The QFX-PFA-4Q, which features a highperformance field-programmable gate array (FPGA), provides four additional QSFP+ ports to the
10
chassis. Each QFX-EM-4Q adds four QSFP+ ports to the chassis and each EX4600-EM-8F adds eight 10-Gigabit SFP+ ports to the chassis. The QFX-EM-4Q ports can also be configured as either access ports or uplink ports, but only ports 0 and 2 can be channelized using port mode. For full details on the different port channelization modes, see "Port Panel of a QFX5100-24Q Device" on page 21. All ports on the QFX5100-24Q and QFX-EM-4Q can be configured as either access ports or uplink ports. This switch provides the hardware support to enable PTP boundary clocks by using the QFX-PFA-4Q module. The QFX5100-24Q-AA also supports GPS in and out signals when QFX-PFA-4Q is installed. The CPU subsystem of this switch includes a 2-port 10-Gigabit Ethernet network interface card (NIC) to provide a high bandwidth path or to alternate traffic path to guest VMs directly from the Packet Forwarding Engine.
Figure 8: QFX5100-24Q-AA Port Panel with QFX-PFA-4Q
The QFX5100-24Q-AA can be used as a standalone switch that supports high frequency statistics collection. Working with Juniper Networks Cloud Analytics Engine, this switch monitors and reports the workload and application behavior across the physical and virtual infrastructure. The QFX5100-24Q-AA supports the following expansion modules to increase port density:
11
· QFX-PFA-4Q (double-wide), which provides four additional QSFP+ ports. See Figure 9 on page 11.
Figure 9: QFX-PFA-4Q Expansion Module
· QFX-EM-4Q (single-wide), which provides 4 additional 40-Gigabit Ethernet QSFP+ ports. See Figure 6 on page 8.
· EX4600-EM-8F (single-wide), which provides 8 additional 10-Gigabit Ethernet SFP+ ports. See Figure 7 on page 9.
The QFX5100-24Q switch supports the QFX-PFA-4Q and you must take the switch offline before replacing the expansion module. Any combination of EX4600-EM-8F and QFX-EM-4Q is also supported. These two expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-8F is inserted instead of a QFX-EM-4Q, the new configuration causes the interfaces to temporarily go down. Likewise, when an EX4600-EM-8F is running on the QFX5100-24Q and is swapped with a QFX-EM-4Q, the interfaces temporarily go down, which can cause a short disruption in traffic. · QFX5100-96S As shown in Figure 10 on page 12, the QFX5100-96S switch is a is a 10-Gigabit Ethernet Enhanced Small Form-Factor Pluggable (SFP+) top-of-rack switch with 96 SFP+ ports and 8 Quad SFP+ (QSFP +) ports. Each SFP+ port can operate as a native 10 Gigabit port, when 10 Gbps optics are used. The SFP+ ports can also run at 1 Gbps, or at 100 Mbps speeds when 1_Gigabit optics are inserted. QSFP + ports 96 and 100 can operate at native 40 Gbps speed or can be channelized to 4 independent 10 Gbps port speeds. The 8 QSFP+ ports can be used as either access ports or as uplinks. The QFX5100-96S switch has a 2 U form factor and comes standard with redundant fans and redundant
12
power supplies. The switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies.

VCF uses Virtual Chassis technology to interconnect multiple devices into a single logical device and manage that device as a single logical device inside of a fabric architecture. VCF architecture supports up to 20 total devices in a spine and leaf topology. Out of the 20 total devices, you can configure a maximum of 4 spine devices. A QFX5100 VCF uses QFX5100 devices as spines or leaf devices. You can also use QFX3500, QFX3600, and EX4300 models as leaf devices in a QFX5100 VCF. Whenever possible, configure the QFX5100-24Q as the spine device in a QFX5100 VCF. · A leaf device in a QFX5110 VCF. A QFX5110 VCF must have a minimum of two QFX5110-32Q as spine devices. Junos OS Release 17.3R1 or later is required for QFX5110 VCF. · A satellite device in a Junos Fusion system. Junos OS Release 14.2.3 or later is required for Junos Fusion.
System Software
QFX Series devices use the Junos operating system (OS), which provides Layer 2 and Layer 3 switching, routing, and security services. Junos OS is installed on a QFX5100 switch's 32-gigabyte (GB) internal solid state flash drive. The same Junos OS code base that runs on QFX5100 switches also runs on all Juniper Networks EX Series switches, M Series, MX Series, and T Series routers. Participation in a QFX5110 Virtual Chassis or a QFX5110 VCF requires the same Junos OS image on all devices in the Virtual Chassis or VCF. Junos OS 17.3R1 or later is the minimum software release for QFX5110 Virtual Chassis or QFX5110 VCF. For more information about which features are supported on QFX Series devices, see Feature Explorer. You manage the switch using the Junos OS command-line interface (CLI), accessible through the console and out-of-band management ports on the device.

Understanding Hardware Redundancy of QFX5100 Device Components and Functionality
The following hardware components provide redundancy on a QFX5100 switch: · Power supplies--The QFX5100 switch has one or two power supplies. Each power supply provides
power to all components in the switch. If two power supplies are installed, the two power supplies provide full power redundancy to the device. If one power supply fails or is removed, the second power supply balances the electrical load without interruption.
18
To provide power redundancy to the system both power supplies must be installed. Connect power source feed A to one power supply and power source feed B to the second power supply.
CAUTION: Do not connect feed A and feed B to the same power supply input terminal.
· Cooling system--The 1 U models of QFX5100 line of switches have five fan modules; the 2 U QFX5100-96S has three fan modules. If a fan module fails and is unable to keep the QFX5100 switch within the desired temperature thresholds, chassis alarms occur and the QFX5100 switch can shut down.
SEE ALSO QFX5100 Power System QFX5100 Cooling System
Field-Replaceable Units in a QFX5100 Device
Field-replaceable units (FRUs) are components that you can replace at your site. The QFX5100 device FRUs are hot-insertable and hot-removable: you can remove and replace one of them without powering off the switch or disrupting the switching function.
CAUTION: Replace a failed power supply with a blank panel or new power supply within one minute of removal to prevent chassis overheating. The switch continues to operate with only one power supply running. Replace a failed fan module with a new fan module within one minute of removal to prevent chassis overheating. Do not operate the switch with missing FRUs for longer than one minute.
Table 2 on page 18 lists the FRUs for the QFX5100 device and actions to take before removing them. Table 2: FRUs in a QFX5100 Switch

Switch Ports
The QFX5100-24Q device ports, (0 through 23) support: · 40 Gbps QSFP+ transceivers · QSFP+ to QSFP+ direct attach copper (DAC) cables · QSFP+ to SFP+ direct attach copper break out (DACBO) cables · QSFP+ to QSFP+ active optical cables (AOC) · QSFP+ to SFP+ active optical breakout cable (AOCBO) · Access ports
You can use 40-Gigabit Ethernet QSFP+ transceivers and QSFP+ direct attach copper cables in any downstream port. See Determining Interface Support for the QFX5100 Device. · Uplink ports You can configure up to 4 of the 40 GbE ports as uplinks. Each additional QFX-EM-4Q, Expansion Module adds the switch uplink capacity by 2 for a total of 8 uplinks. To connect a QFX5100-24Q switch as a Node device in a QFabric system, you need: · Four QSFP+ uplink ports on each QFX5100-24Q Node device to connect to the data plane
network through the QFX3008-I or QFX5100-24Q Interconnect devices. · Two additional QSFP+ uplink ports on each QFX5100-24Q Node device connect to the data
plane network through the QFX3008-I or QFX5100-24Q Interconnect devices. .
QFabric Systems
The QFX5100-24Q operates as a Node device in both the QFX3000-G and QFX3000-M QFabric systems. Additionally, the QFX5100-24Q can be configured as an Interconnect Device in QFX3000-M QFabric systems allowing a maximum of 16 Node devices. The QFX5100-24Q may not be mixed with QFX3600-I Interconnect devices in the same QFabric system. When operating as a Node device, ports 0 through 7 are default FTE ports; ports 8 through 15 can be configured as either uplink (FTE) or access ports (XLE). In the port range 8 through 23, only 12 ports can be channelized when the 2 QFX-EM-4Q are installed.
NOTE: The EX4600-EM-8S expansion module is not supported on the QFX5100-24Q device in a QFabric system.
23
Channelizing Interfaces (Non-QFabric)
When fully populated with 2 QFX-EM-4Q Expansion Modules, the QFX5100-24Q device has 128 physical ports. However, only 104 logical ports can be used for port channelization. Depending on the system mode you configure for channelization, different ports are restricted. If you attempt to channelize a restricted port, the configuration is ignored. The following system modes are available on the QFX5100-24Q device:
· Default mode
All 24 QSFP+ ports on the switch (PIC 0) are channelized by default (96 ports). With QFX-EM-4Q Expansion Modules (PIC 1) and (PIC 2), the QSFP+ ports are supported for access or uplink ports, but cannot be channelized. Ports are over-subscribed In this mode and could be subject to packet-loss. You can have one of two port combinations: 32 40-Gbps QSFP+ ports, or 96 10-Gigabit Ethernet ports plus 8 40-Gbps QSFP+ ports.
· 104 port mode
All 24 QSFP+ ports on the switch (PIC 0) are channelized (96 ports). Two ports on QFX-EM-4Q Expansion Module (PIC 1) are also channelized (8 additional). In this mode, ports 0 and 2 are channelized by default and ports 1 and 3 are disabled. If additional QSFP+ ports are detected in an expansion module (PIC 2), those ports are ignored.
· Flexi-pic mode
Ports 0 through 3 of the switch cannot be channelized; ports 4 through 24 are channelized by default (80 ports). With QFX-EM-4Q Expansion Modules (PIC 1) and (PIC 2), the QSFP+ ports are supported for access or uplink ports, but cannot be channelized. With EX4600-EM-8F Expansion Modules installed (PIC 1) and (PIC 2), the 16 SFP+ ports of SFP are recognized for a total of 96 logical ports.
· Non-oversubscribed mode
All 24 QSFP+ ports on the switch (PIC 0) are channelized (96 ports). Expansion modules on PIC 1 and PIC 2 are not supported and cannot be channelized. There is no packet loss for packets of any size in this mode.
Virtual Chassis and Virtual Chassis Fabric
The QFX5100-24Q device operates as a standalone switch, a member of a QFX Virtual Chassis, or as a spine or leaf device in a QFX5100 Virtual Chassis Fabric (VCF). QFX Virtual Chassis support up to 10 members. QFX5100 VCF supports 20 QFX5100 and EX4300 devices, of which 4 QFX5100 devices can be configured as spines.
To connect a QFX5100-24Q device as a member in a QFX Virtual Chassis, you need to cable a pair of ports to link each member in the Virtual Chassis into a ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP) connection to each directly connected member.
24
QFX5100-24Q devices are recommended in the primary, backup, or line card role. When mixed with QFX3500 or QFX3600 devices, configure the QFX5100-24Q device in the primary and backup roles. See Connecting QFX Series and EX Series Switches in a QFX Virtual Chassis for cabling diagrams. The Virtual Chassis feature is not applicable to QFX devices in a QFabric. To connect a QFX5100-24Q device as a spine or leaf device in a QFX5100 VCF, you need to cable a set of ports as VCP connections that link each spine device and leaf device. All spine devices have at least one direct VCP connection to each leaf device in the VCF. Non-channelized DAC cables can be configured as VCP connections. See Connecting a QFX5100 Device in a Virtual Chassis Fabric for a cabling diagram.
BEST PRACTICE: Whenever possible use the QFX5100-24Q device as a spine device. By using the QFX5100-24Q device in a maximum configuration of 20 total devices, four QFX5100-24Q devices may be used as spine devices. All members can be connected to the spine using QSFP+ ports.
As of Junos OS release 17.3R1, you can also connect a QFX5100-24Q as a leaf device in a QFX5110 VCF or as a member in a QFX5110 Virtual Chassis.

Port Panel of a QFX5100-24Q-AA Device
The port panel of the QFX5100-24Q-AA switch consists of 24 quad small-form factor pluggable plus (QSFP+) 40-Gigabit Ethernet ports. Each QSFP+ socket can be configured to support 40-Gigabit Ethernet or as a set of four independent 10-Gigabit Ethernet ports using breakout cables (channelization mode). The QFX5100-24Q-AA can also be configured to support 96 10-Gigabit Ethernet ports using breakout cables (channelization mode) with 1280 Gbps output. Any of the 24 ports can be configured as either an uplink port or an access port.
26
The expansion module bay of the QFX5100-24Q switch is located on the port panel. In the expansion module bay, you can install a single double-wide expansion module (QFX-PFA-4Q) or two single-wide optional expansion modules (QFX-EM-4Q and EX4600-EM-8F, in any combination). When you install two single-wide expansion modules, the slot on your left hand side is slot 1 (QIC0), and the slot on your right hand side is slot 2 (QIC1).
The QFX-PFA-4Q module adds four QSFP+ ports to the chassis. The QFX-EM-4Q module adds four QSFP+ ports to the chassis and the EX4600-EM-8F module adds eight 10-Gigabit SFP+ ports to the chassis. The QFX-EM-4Q ports can be configured as either access ports or as uplinks ports, but only ports 0 and 2 can be channelized by using port mode. The QFX-EM-4Q ports can also be configured as either access ports or uplink ports, but only ports 0 and 2 can be channelized by using port mode. Figure 13 on page 26 shows the port panel of the QFX5100-24Q-AA device.

Port Panel of QFX5100-48S and QFX5100-48SH Devices
The port panel of the QFX5100-48S and QFX5100-48SH switches supports up to a maximum of 72 logical 10 GbE ports when operating as a standalone switch. Forty-eight physical ports(0 through 47) support 10 Gigabit Ethernet small form-factor pluggable plus (SFP+) transceivers. These ports can also support 1 Gigabit SFP transceivers and can be configured at either 1 Gbps or 1 Gbps speeds using the set interface speed command. All 48 of these ports can be used for SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP+, 10-Gigabit Ethernet SFP+ transceivers and SFP+ DAC cables in any access port.
The remaining 24 logical ports are the six 40 GbE physical ports (48 through 53) that support up to 6 quad small-form factor pluggable plus (QSFP+) transceivers . Each QSFP+ socket can operate either as a
27
single 40 Gbps port or as a set of 4 independent 10 Gbps ports using QSFP+ breakout cables. The 40 GbE ports can be configured as either access ports or as uplinks.
CAUTION: Do not install 1GbE copper transceivers (such as QFX-SFP-1GE-T) directly above or below another 1GbE copper transceiver. Use only the top row or bottom row to avoid damage to the device caused by some types of copper transceivers when the transceivers are installed above or below each other. However, if you are using copper transceivers with the OEM part number FCLF8521P2BTL-J1 printed on the transceiver label, you can install the transceivers in any port with no restrictions. For devices that support 10GbE copper transceivers, there is no similar restriction.
To connect a QFX5100-48S switch as a node device in a QFabric system, you need:
· Four QSFP+ uplink ports on each QFX5100-48S Node device to connect to the data plane network through the QFX3008-I or QFX5100-24Q Interconnect devices.
· The two remaining QSFP+ uplink ports on each QFX5100-48S Node device connect to the data plane network through the QFX3008-I or QFX5100-24Q Interconnect devices. See Determining Interface Support for the QFX5100 Device.
To connect a QFX5100-48S switch as a member in a QFX Virtual Chassis, you need a pair of dedicated ports and cables that link each member in the Virtual Chassis into a ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP) connection to a upstream and downstream member. QFX5100-48S switches are recommended in the primary, backup, or line card role. When mixed with QFX3500 or QFX3600 devices, configure the QFX5100-48S in the primary and backup roles. See Connecting QFX Series and EX Series Switches in a QFX Virtual Chassis for cabling diagrams.
To connect a QFX5100-48S switch as a spine or leaf device in a QFX5100 Virtual Chassis Fabric (VCF), you need a pair of dedicated ports and cables that link each spine device and leaf device in the VCF. All spine devices have at least one direct VCP connection to each leaf device in the VCF. See Connecting a QFX5100 Device in a Virtual Chassis Fabric for a cabling diagram.
BEST PRACTICE: In a mixed QFX5100 VCF environment with multiple models of QFX5100 and the EX4300, use QFX5100-24Q as spine devices. In the maximum configuration of 20 total devices, up to four QFX5100-24Q devices may be used as spine devices. All members can be connected to the spine using QSFP+ ports. You can configure the QFX5100-96S as a spine in an all QFX5100-96S VCF or in a mixed VCF comprised of EX4300 and QFX5100-96S.
As of Junos OS release 17.3R1, you can also connect a QFX5100-48S as a leaf device in a QFX5110 VCF or as a member in a QFX5110 Virtual Chassis.

The port panel of the QFX5100-96S switch consists of 96 small form-factor pluggable plus (SFP+) and 8 quad small-form factor pluggable plus (QSFP+) ports that are normally configured as access ports. Physical ports(0 through 95) support 10 Gbps SFP+ transceivers and 1 Gbps transceivers. The eight 40Gigabit ports (96 through 104) support QSFP+ transceivers and are normally configured as uplinks or Virtual Chassis ports (VCPs). Although the 104 physical ports of the QFX5100-96S would map to 128 logical ports using channelization, only 104 logical ports are supported.

CAUTION: Do not install 1GbE copper transceivers (such as QFX-SFP-1GE-T) directly above or below another 1GbE copper transceiver. Use only the top row or bottom row to avoid damage to the device caused by some types of copper transceivers when the transceivers are installed above or below each other. However, if you are using copper transceivers with the OEM part number FCLF8521P2BTL-J1 printed on the transceiver label, you can install the transceivers in any port with no restrictions. For devices that support 10GbE copper transceivers, there is no similar restriction.
Channelizing Interfaces
The port panel of the QFX5100-96S switch supports up to a maximum of 104 logical 10 GbE ports that can be distributed over 96 small form-factor pluggable plus (SFP+) and 8 quad small-form factor pluggable plus (QSFP+) transceivers . Because of an 104 port restriction, only two of the eight QSFP+ can be channelized. Depending on how you set the system mode for channelization, the behavior of channelization for the QSFP+ changes. The following system modes are available for the QFX5100-96S switch:
· Non-oversubscribed
All 96 SFP+ ports on the switch (PIC 0) are supported. In this mode, the eight QSFP+ ports are not supported and cannot be channelized. There is no packet loss for packets of any size in this mode.
· Default mode
All 96 SFP+ ports on the switch (PIC 0) are supported. QSFP+ ports 96 and 100 can be channelized. If ports 96 and 100 are channelized, the interfaces on ports 97, 98, 99, 101, 102, and 103 are disabled.
Virtual Chassis and Virtual Chassis Fabric Support
The QFX5100-96S switch operates as a standalone switch, as a member in a QFX Virtual Chassis, as a member in a QFX5110 Virtual Chassis, as a spine or leaf device in a QFX5100 Virtual Chassis Fabric (VCF), or as a leaf device in a QFX5110 VCF. QFX Virtual Chassis support up to 10 members; QFX5100 VCF supports a total of 20 devices, of which 4 QFX5100 devices can be configured as spines. A QFX Virtual Chassis is cabled in a ring topology, where a VCF is cabled in a spine and leaf topology.
Virtual Chassis
In a QFX Virtual Chassis, you can connect up to 10 standalone QFX5100-96S switches into a QFX Series Virtual Chassis and manage the interconnected switches as a single chassis. The advantages of
33
connecting multiple switches into a Virtual Chassis include better-managed bandwidth at a network layer, simplified configuration and maintenance because multiple devices can be managed as a single device, increased fault tolerance and high availability (HA) because a Virtual Chassis can remain active and network traffic can be redirected to other member switches when a single member switch fails, and a flatter, simplified Layer 2 network topology that minimizes or eliminates the need for loop prevention protocols such as Spanning Tree Protocol (STP). As of Junos OS release 17.3R1, you can also connect a QFX5100-96S as a member in a QFX5110 Virtual Chassis. Virtual Chassis Fabric The VCF provides a low-latency, high-performance fabric architecture that can be managed as a single device. VCF is an evolution of the Virtual Chassis feature, which allows you to interconnect multiple devices into a single logical device, inside of a fabric architecture. The VCF architecture is optimized to support small and medium-sized data centers that contain a mix of 1-Gpbs, 10-Gpbs, and 40-Gbps Ethernet interfaces. A VCF is constructed using a spine-and-leaf architecture and topology. In the spine-and-leaf architecture, each spine device is interconnected to each leaf device. A VCF supports up to 20 devices, of which 4 QFX5100 devices can be configured into spine devices. In a mixed environment with QFX5100-24Q, QFX5100-98S and EX4300, use the QFX5100-24Q as the spine device and the QFX5100-96S and EX4300 as a leaf devices. You may use the QFX5100-96S as a spine in an all QFX5100-96S VCF or in a VCF that has a mixture of QFX5100-96S and EX4300. As of Junos OS release 17.3R1, you can also connect a QFX5100-24Q as a leaf device in a QFX5110 VCF.
Expansion Modules for QFX5100 Devices
IN THIS SECTION EX4600-EM-8F | 34 QFX-EM-4Q | 36 QFX-PFA-4Q | 37
The QFX5100-24Q and QFX5100-24Q-AA devices have two bays on the port panel for optional expansion modules. These expansion modules can be hot-inserted or hot-removed. Expansion modules and transceivers are not shipped with the switch and must be ordered separately.
34
The QFX5100-24Q and QFX5100-24Q-AA support these expansion modules up to the 104-port limitation:
· Two EX4600-EM-8F, which provides a total of 16 additional 10-Gigabit Ethernet Enhanced Small Form-Factor Pluggable (SFP+) ports or 8 additional 1-Gigabit SFP ports. When both bays (PIC 1 and PIC 2) are populated with EX4600-EM-8F modules, you must configure the system mode as Flexipic. In this mode, port 0 to 3 of PIC 0 are disabled, which allows the devices to operate within the 104-port limitation.
· Two QFX-EM-4Q, which provides a total of 8 additional 40-Gigabit Quad SFP+ (QSFP+) ports.
· One EX4600-EM-8F and one QFX-EM-4Q, which provides 8 additional 10-Gigabit Ethernet SFP+ (or 8 additional 1-Gigabit SFP ports) and 4 additional 40-Gigabit (QSFP+) ports. This combination requires the system mode to be configured as Flexi-pic. See Configuring the System Mode.
Additionally, the QFX5100-24Q-AA supports the QFX-PFA-4Q expansion module, which provides 4 additional QSFP+ ports.
NOTE: In order to run the orchestration diagnostics, Precision Time Protocol (PTP) and synchronization diagnostics, and utilities contained in the Packet Flow Accelerator Diagnostics software, you must have Junos OS Release 14.1X53-D27 or later software with enhanced automation installed on your QFX5100-24Q-AA.
EX4600-EM-8F
The EX4600-EM-8F is a MACsec-capable expansion module that inserts into one of the device bays of a QFX5100-24Q, QFX5100-24Q-AA, or an EX4600 switch. It provides 8 additional 10-Gigabit Ethernet SFP+ ports or 8 additional 1-Gigabit SFP ports to each bay. Figure 7 shows the ports and LEDs on the expansion module.
CAUTION: Copper SFP transceivers (1000BASE-T) are restricted to the top four ports or the bottom four ports; fiber SFP transceivers (1000BASE-X) can be used in any of the
35
eight ports. Attempting to stack copper SFP transceivers causes internal damage to the module.
Figure 17: EX4600-EM-8F Faceplate and LEDs
1-- Expansion module status LED
2-- SFP+ port LEDs
When the expansion module is inserted into the expansion bay, the chassis detects the additional ports, recognizes them as 10GbE ports, and lights the Status LED. The QFX5100-24Q device is configured for the QFX-EM-4Q by default, but any combination of the two modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-4Q is inserted instead of the default QFX-EM-4Q, the Packet Forwarding Engine reboots that can cause some temporary disruption in traffic. See Configuring the System Mode.
NOTE: MACsec is supported on the 10-Gigabit Ethernet ports with the EX-QFX-MACSEC-AGG license.

AC Power Supply for a QFX5100 Device
The two power supplies in QFX5100 switches are hot-removable and hot-insertable field-replaceable units (FRUs). The power supplies are installed in the switch at the factory. You can install replacement power supplies from the management panel without powering off the switch or disrupting the switching function. The AC power supply in 1 U QFX5100 switches is 650 W; the AC power supply in the 2 U, QFX5100-96S switch, is 850 W. Both power supplies look identical. Be sure to use the correct power supply for your chassis product SKU (see Table 13 on page 59).
CAUTION: Do not mix power supplies with different airflow or different wattage. The system raises an alarm when a power supply having a different airflow or wattage is inserted into the chassis.
57
See Figure 26 on page 57 for an example of the 1 U design and Figure 27 on page 57 for an example of the 2 U power supply.

Figure 27: 2 U AC Power Supply in a QFX5100-96S Switch
The power supply provides FRU-to-port or port-to-FRU airflow depending on the product SKU you purchase. On legacy switches, or switches with an LCD, this airflow is called back-to-front and front-toback. The power supplies have color-coded handles with a fan icon. See Figure 28 on page 58 for an
58 example of the power supply. A power supply with a blue handle denotes FRU-to-port airflow; a power supply with a gold-colored handle denotes port-to-FRU airflow. Figure 28: Power Supply Handle Detail
1-- Fan icon on handle CAUTION: Verify that the airflow direction on the power supply handle matches the direction of airflow in the chassis. Ensure that each power supply you install in the chassis has the same airflow direction. If you install power supplies with two different airflow directions, Junos OS raises an alarm. If you need to convert the airflow pattern on a chassis, you must change out all the fans and power supplies at one time to use the new direction.
Table 13 on page 59 shows the different power supplies and their direction of airflow.

IN THIS SECTION Fan Modules | 71 Do Not Install Components with Different Airflow or Wattage in the Switch | 77 Fan Module Status | 78
The cooling system in an QFX5100 device consists of fan modules and a single fan in each power supply. The number of fan modules vary depending whether the size of the switch is 1 U or 2 U high. All switches can be set up to work in one of two airflow directions: · Airflow InAir comes into the switch through the vents in the field-replaceable units (FRUs) · Airflow OutAir comes into the switch through the vents in the port panel.
CAUTION: Airflow In and Airflow Out fans and power supplies cannot be mixed in the same chassis.
71
Fan Modules
The fan modules in QFX5100 devices are hot-insertable and hot-removable field-replaceable units (FRUs). These fan modules are designed for one of the two available airflow directions (Airflow In or Airflow Out). Some fan modules are also color-coded for the airflow direction as well. The fan modules are installed in the fan module slots on the management panel of the switch next to the power supplies.
Both the 1 U and 2 U versions of QFX5100 fan modules have a similar design with different dimensions. The 1 U QFX5100 devices have 5 fan modules numbered 0 through 4 from left to right, where the 2 U, QFX5100-96S device, has 3 fan modules numbered 0 through 2. On all QFX5100 devices, each fan module slot has a fan icon next to it.
72 Figure 35 on page 72 shows the 1 U fan module and Figure 36 on page 72 shows the 2 U fan module. Figure 35: 1 U Fan Module Used in QFX5100 Switches
Figure 36: 2 U Fan Module Used in QFX5100-96S Switches
You remove and replace a fan module from the FRU end of the chassis. The switch continues to operate for a limited period of time (30 seconds) during the replacement of the fan module without thermal shutdown.
73
NOTE: All fan modules must be installed for optimal operation of the switch.
The fan modules are available in two product SKUs that have different airflow directions--FRU-to-port airflow, indicated on some units by the azure blue color or a label. FRU-to-port airflow versions of the fan module that have labels are marked AIR IN . Likewise, port-to-FRU airflow is indicated by either a gold color or the label AIR OUT . On legacy switches or switches with LCDs, this airflow is also called front-to-back and back-to-front. Table 19 on page 73 lists the available fan module product SKUs and the direction of airflow in them:

Do Not Install Components with Different Airflow or Wattage in the Switch
Do not mix power supplies with different airflow. If the power supplies are color-coded, ensure they are either all azure blue for airflow in models or all gold for airflow out models. If the power supplies are not color-coded but have a label, ensure that the chassis is either using all airflow in ( AFI ) or all airflow out (AFO). Likewise, ensure that all fan modules have the same airflow and match the airflow of the power supplies. Fan modules are also either color-coded azure blue for airflow in or gold for airflow out. If the fan module has a label instead of being color-coded, ensure that labels (AIR IN and AIR OUT ) are not mixed. If the fan modules have AIR IN labels, the power supplies must also have AIR IN labels; if the fan modules have AIR OUT labels, the power supplies must also have AIR OUT labels. Mixing components with different airflows in the same chassis hampers the performance of the cooling system of the switch and leads to overheating of the chassis.
CAUTION: The system raises an alarm if a fan module fails or if the ambient temperature inside the chassis rises above the acceptable range. If the temperature inside the chassis rises above the threshold temperature, the system shuts down automatically.
78
Do not mix fan modules with different wattage. Only use the replacement fan modules that are designed for use with your product number. See Table 19 on page 73 for the correct part number for your QFX5100 device.
CAUTION: Do not mix AC and DC power supplies in the same chassis.
However if you need to convert a QFX5100 device to have a different airflow, you can change the airflow pattern. To convert an AIR IN product SKU to an AIR OUT product SKU or an AIR OUT product SKU to a AIR IN product SKU, you must replace all of the fans and power supplies at one time to use the new direction. The system raises an alarm when the system is converted, which is normal.
Fan Module Status
You can check the status of fan modules through the show system alarms command or by looking at the LEDs next to each fan module.
Each switch has a Status LED (labeled ST) for each fan module on the left side of the corresponding fan module slot. It indicates the status of all the fan modules. Table 20 on page 78 describes the Status LED on the fan module in a QFX5100 device.
Table 20: Fan Module LED

An error has been detected in the fan module. Replace the fan module as soon as possible. Either the fan has failed or it is seated incorrectly. To maintain proper airflow through the chassis, leave the fan module installed in the chassis until you are ready to replace it.
Clearance Requirements for Airflow and Hardware Maintenance for a QFX5100 Device
When planning the site for installing a QFX5100 device, you must allow sufficient clearance around the installed chassis (see Figure 42 on page 80).
Figure 42: Clearance Requirements for Airflow and Hardware Maintenance for a QFX5100 Device
81
· For the cooling system to function properly, the airflow around the chassis must be unrestricted. See Cooling System and Airflow in a QFX5100 Device for more information about the airflow through the chassis.
· If you are mounting a QFX5100 device in a rack or cabinet with other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.
· Leave at least 24 in. (61 cm) both in front of and behind the QFX5100 device. For service personnel to remove and install hardware components, you must leave adequate space at the front and back of the switch. NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the rack or cabinet.

General Site Guidelines
Efficient device operation requires proper site planning and maintenance and proper layout of the equipment, rack or cabinet (if used), and wiring closet. To plan and create an acceptable operating environment for your device and prevent environmentally caused equipment failures: · Keep the area around the chassis free from dust and conductive material, such as metal flakes. · Follow prescribed airflow guidelines to ensure that the cooling system functions properly and that
exhaust from other equipment does not blow into the intake vents of the device. · Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the
equipment. Static discharge can cause components to fail completely or intermittently over time. · Install the device in a secure area, so that only authorized personnel can access the device.
Site Electrical Wiring Guidelines
Table 24 on page 88 describes the factors you must consider while planning the electrical wiring at your site.
WARNING: You must provide a properly grounded and shielded environment and use electrical surge-suppression devices. Avertissement Vous devez établir un environnement protégé et convenablement mis à la terre et utiliser des dispositifs de parasurtension.

Guidelines
Signaling limitations
If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding:
· Improperly installed wires cause radio frequency interference (RFI).
· Damage from lightning strikes occurs when wires exceed recommended distances or pass between buildings.
· Electromagnetic pulses (EMPs) caused by lightning damage unshielded conductors and electronic devices.
Radio frequency interference
To reduce or eliminate RFI from your site wiring, do the following:
· Use a twisted-pair cable with a good distribution of grounding conductors.
· If you must exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.
Electromagn etic compatibilit y
If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice.
Some of the problems caused by strong sources of electromagnetic interference (EMI) are:
· Destruction of the signal drivers and receivers in the device
· Electrical hazards as a result of power surges conducted over the lines into the equipment
Grounding Cable and Lug Specifications for a QFX5100 Device
For installations that require a separate grounding conductor to the chassis, the switch must be adequately grounded before power is connected to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground a QFX5100 device, connect a grounding cable to earth ground and then attach it to the chassis grounding points.
89
WARNING: The switch is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth ground for installations that require a separate grounding conductor to the chassis.
WARNING: To comply with GR-1089 requirements, all intra-building copper cabling used for SFP+ and QSFP+ ports must be shielded and grounded at both ends.
CAUTION: Before switch installation begins, a licensed electrician must attach a cable lug to the grounding cables that you supply. See "Connecting Earth Ground to a QFX5100 Device" on page 142. A cable with an incorrectly attached lug can damage the switch.
Before connecting the switch to earth ground, review the following information: · A protective earthing terminal bracket is provided in the accessory kit for connecting the switch to
earth ground. This L-shaped bracket attaches to the side of the QFX5100 chassis through the mounting bracket, providing a protective earthing terminal for the switch. · The grounding lug required is a Panduit LCD10-10A-L or equivalent (not provided).. The grounding lug should accommodates 1410 AWG (25.3 mm²) stranded wire. · The grounding cable that you provide for a QFX5100 device must be 14 AWG (2 mm²), minimum 60° C wire, or as permitted by the local code. · Ensure you have two SAE 10-32 washers and screws to attach the cable and bracket (not provided).

Mounting bracket hole spacing (all product SKUs)
The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the switch can be mounted in any rack that provides holes spaced at that distance.
91
Table 25: Rack Requirements for the QFX5100 Device (Continued)
Rack Requirement
Guidelines
Rack size and strength (all product SKUs)
· Ensure that the rack complies with the standards for a 19-in. or 23-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310D) published by the Electronics Industry Association.
· A 600-mm rack as defined in the four-part Equipment Engineering (EE); European telecommunications standard for equipment practice (document numbers ETS 300 119-1 through 119-4) published by the European Telecommunications Standards Institute.
The horizontal spacing between the rails in a rack that complies with this standard is usually wider than the device's mounting brackets, which measure 19 in. (48.26 cm) from outer edge to outer edge. Use approved wing devices to narrow the opening between the rails as required.
· Ensure that the rack rails are spaced widely enough to accommodate the switch chassis' external dimensions. The outer edges of the frontmounting brackets extend the width to 28.5 in. (72.4 cm) to 31.5 in. (80 cm).
· For four-post installations, the front and rear rack rails must be spaced between 28.5 in. (72.4 cm) to 31.5 in. (80 cm) front-to-back.
· The rack must be strong enough to support the weight of the switch.
· Ensure that the spacing of rails and adjacent racks allows for proper clearance around the switch and rack.
Rack connection to building structure
· Secure the rack to the building structure.
· If earthquakes are a possibility in your geographical area, secure the rack to the floor.
· Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum stability.

Guidelines
Cabinet airflow requirements
When you mount the switch in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.
· Ensure that the cool air supply you provide through the cabinet adequately dissipates the thermal output of the switch (or switches).
· Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet without recirculating into the switch. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.
· The QFX5100 device fans exhaust hot air either through the vents on the port panel or through the fans and power supplies. Install the switch in the cabinet in a way that maximizes the open space on the FRU side of the chassis. This maximizes the clearance for critical airflow.
· Route and dress all cables to minimize the blockage of airflow to and from the chassis.
· Ensure that the spacing of rails and adjacent cabinets allows for the proper clearance around the switch and cabinet.

Plan a Virtual Chassis Fabric Deployment
A Virtual Chassis Fabric (VCF) architecture supports up to 20 interconnected devices that are managed as a logical single device. Supported platforms vary depending on the QFX Series switch chosen for the spine. See "Understanding Virtual Chassis Fabric Components" and "Virtual Chassis Fabric Hardware Overview" for supported configurations. Although the architecture has a powerful auto-provisioning option, which allows you to plug and play the devices, careful planning of the deployment can avoid unexpected results.
For example, if you perform any configuration level commands on one of the devices (including assigning IP addresses or host names) you no longer can use auto-provisioning.

Cable Specifications for QSFP+ and QSFP28 Transceivers
The 40-Gigabit Ethernet QSFP+ and 100-Gigabit Ethernet QSFP28 transceivers that are used in QFX Series switches use 12-ribbon multimode fiber crossover cables with socket MPO/UPC connectors. The fiber can be either OM3 or OM4. These cables are not sold by Juniper Networks.
CAUTION: To maintain agency approvals, use only a properly constructed, shielded cable.
TIP: Ensure that you order cables with the correct polarity. Vendors refer to these crossover cables as key up to key up, latch up to latch up, Type B, or Method B. If you are using patch panels between two QSFP+ or QSFP28 transceivers, ensure that the proper polarity is maintained through the cable plant.

Understanding QFX Series Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion
IN THIS SECTION Signal Loss in Multimode and Single-Mode Fiber-Optic Cables | 105 Attenuation and Dispersion in Fiber-Optic Cable | 105
105
To determine the power budget and power margin needed for fiber-optic connections, you need to understand how signal loss, attenuation, and dispersion affect transmission. The QFX Series uses various types of network cables, including multimode and single-mode fiber-optic cables.
Signal Loss in Multimode and Single-Mode Fiber-Optic Cables
Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs as light sources. However, LEDs are not coherent light sources. They spray varying wavelengths of light into the multimode fiber, which reflect the light at different angles. Light rays travel in jagged lines through a multimode fiber, causing signal dispersion. When light traveling in the fiber core radiates into the fiber cladding (layers of lower refractive index material in close contact with a core material of higher refractive index), higher-order mode loss occurs. Together, these factors reduce the transmission distance of multimode fiber compared to that of single-mode fiber.
Single-mode fiber is so small in diameter that rays of light reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared to multimode fiber, singlemode fiber has a higher bandwidth and can carry signals for longer distances. It is consequently more expensive.
For information about the maximum transmission distance and supported wavelength range for the types of single-mode and multimode fiber-optic cables that are connected to the QFX Series, see the Hardware Compatibility Tool. Exceeding the maximum transmission distances can result in significant signal loss, which causes unreliable transmission.
Attenuation and Dispersion in Fiber-Optic Cable
An optical data link functions correctly provided that modulated light reaching the receiver has enough power to be demodulated correctly. Attenuation is the reduction in strength of the light signal during transmission. Passive media components such as cables, cable splices, and connectors cause attenuation. Although attenuation is significantly lower for optical fiber than for other media, it still occurs in both multimode and single-mode transmission. An efficient optical data link must transmit enough light to overcome attenuation.
Dispersion is the spreading of the signal over time. The following two types of dispersion can affect signal transmission through an optical data link:
· Chromatic dispersion, which is the spreading of the signal over time caused by the different speeds of light rays.
· Modal dispersion, which is the spreading of the signal over time caused by the different propagation modes in the fiber.
106
For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually limits the maximum bit rate and link length. For single-mode transmission, modal dispersion is not a factor. However, at higher bit rates and over longer distances, chromatic dispersion limits the maximum link length. An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications. In addition, the total dispersion must be within the limits specified for the type of link in the Telcordia Technologies document GR-253-CORE (Section 4.3) and International Telecommunications Union (ITU) document G.957. When chromatic dispersion is at the maximum allowed, its effect can be considered as a power penalty in the power budget. The optical power budget must allow for the sum of component attenuation, power penalties (including those from dispersion), and a safety margin for unexpected losses.
Calculating Power Budget and Power Margin for Fiber-Optic Cables
IN THIS SECTION How to Calculate Power Budget for Fiber-Optic Cable | 106 How to Calculate Power Margin for Fiber-Optic Cable | 107
Use the information in this topic and the specifications for your optical interface to calculate the power budget and power margin for fiber-optic cables.
TIP: You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device.
To calculate the power budget and power margin, perform the following tasks:
How to Calculate Power Budget for Fiber-Optic Cable
To ensure that fiber-optic connections have sufficient power for correct operation, you need to calculate the link's power budget, which is the maximum amount of power it can transmit. When you calculate the power budget, you use a worst-case analysis to provide a margin of error, even though all the parts of an actual system do not operate at the worst-case levels. To calculate the worst-case estimate of power budget (PB), you assume minimum transmitter power (PT) and minimum receiver sensitivity (PR):
107
PB = PT PR
The following hypothetical power budget equation uses values measured in decibels (dB) and decibels referred to one milliwatt (dBm):
PB = PT PR
PB = 15 dBm (28 dBm)
PB = 13 dB
How to Calculate Power Margin for Fiber-Optic Cable
After calculating a link's power budget, you can calculate the power margin (PM), which represents the amount of power available after subtracting attenuation or link loss (LL) from the power budget (PB). A worst-case estimate of PM assumes maximum LL:
PM = PB LL
PM greater than zero indicates that the power budget is sufficient to operate the receiver.
Factors that can cause link loss include higher-order mode losses, modal and chromatic dispersion, connectors, splices, and fiber attenuation. Table 30 on page 107 lists an estimated amount of loss for the factors used in the following sample calculations. For information about the actual amount of signal loss caused by equipment and other factors, refer to vendor documentation. Table 30: Estimated Values for Factors Causing Link Loss
Link-Loss Factor
Estimated Link-Loss Value
Higher-order mode losses
Single mode--None Multimode--0.5 dB
Modal and chromatic dispersion Single mode--None
Multimode--None, if product of bandwidth and distance is less than 500 MHz-km

Splice

108
Table 30: Estimated Values for Factors Causing Link Loss (Continued)
Link-Loss Factor
Estimated Link-Loss Value
Fiber attenuation
Single mode--0.5 dB/km Multimode--1 dB/km
The following sample calculation for a 2-km-long multimode link with a power budget (PB) of 13 dB uses the estimated values from Table 30 on page 107 to calculate link loss (LL) as the sum of fiber attenuation (2 km @ 1 dB/km, or 2 dB) and loss for five connectors (0.5 dB per connector, or 2.5 dB) and two splices (0.5 dB per splice, or 1 dB) as well as higher-order mode losses (0.5 dB). The power margin (PM) is calculated as follows:
PM = PB LL
PM = 13 dB 2 km (1 dB/km) 5 (0.5 dB) 2 (0.5 dB) 0.5 dB
PM = 13 dB 2 dB 2.5 dB 1 dB 0.5 dB
PM = 7 dB
The following sample calculation for an 8-km-long single-mode link with a power budget (PB) of 13 dB uses the estimated values from Table 30 on page 107 to calculate link loss (LL) as the sum of fiber attenuation (8 km @ 0.5 dB/km, or 4 dB) and loss for seven connectors (0.5 dB per connector, or 3.5 dB). The power margin (PM) is calculated as follows:
PM = PB LL
PM = 13 dB 8 km (0.5 dB/km) 7(0.5 dB)
PM = 13 dB 4 dB 3.5 dB
PM = 5.5 dB
In both examples, the calculated power margin is greater than zero, indicating that the link has sufficient power for transmission and does not exceed the maximum receiver input power.

Virtual Chassis Fabric Installation Overview
For best results, ensure you review and understand the Virtual Chassis Fabric (VCF) configuration options. These configuration options are explained in "Virtual Chassis Fabric Hardware Overview" and "Understanding Virtual Chassis Fabric Configuration". Do not interconnect the switches with cables until directed in the procedure.
1. Install the individual switches in a rack or cabinet following the guidelines in "Plan a Virtual Chassis Fabric Deployment" on page 94.
BEST PRACTICE: Install spine devices at the top of the rack or cabinet in order of primary routing engine (RE), backup RE, and then other leaf devices.
2. Make a list of all of the serial numbers of the devices. 3. Log into each device and configure into fabric mode and mixed mode, if needed. Mixed mode is only
necessary for QFX5100 VCF when QFX5100-96S, QFX5100-48T, QFX3500, QFX3600, or EX4300 devices are present as leaf devices in the configuration. If a spine device is not properly configured in fabric and mixed mode for QFX5100 mixed VCF, the VCF devices reboot to commit the mixed mode or fabric settings. When fabric and mixed mode are not set, you might need to manually correct any issues that are related to the VCF not forming correctly because the device did not immediately join the VCF.
WARNING: Only configure operational-level commands. If you commit any configuration-level commands (including assigning IP address), the Virtual Chassis Fabric cannot form and the switch must be zeroed.
4. Configure the VCF into mixed mode if it is a QFX5100 VCF and the switch models span different lines of switches.
118
5. Configure each device for one of the provisioning modes: autoprovision, preprovision, or nonprovision. See: · "Autoprovisioning a Virtual Chassis Fabric"
· "Preprovisioning a Virtual Chassis Fabric"
· "Configuring a Nonprovisioned Virtual Chassis Fabric" 6. Connect and configure one of the management ports (C0) or (C1) to a management switch as the
Virtual Management Ethernet interface. Using this interface, you can configure and manage the devices in the VCF. See "Connect a Device to a Network for Out-of-Band Management". 7. Commit your changes. 8. Cable the ports that you will use as VCPs. For cabling examples, see "Connecting QFX5110 in a QFX5110 Virtual Chassis Fabric", "Connecting a QFX5100 Device in a Virtual Chassis Fabric" on page 139, "Connecting a QFX3500 or QFX3600 Switch in a QFX5100 Virtual Chassis Fabric", and "Connecting EX Series Switches in a QFX5100 Virtual Chassis Fabric". If you configured your devices as either autoprovisioned or preprovisioned, the Virtual Chassis ports (VCP) are automatically configured. If you configure the devices as nonprovisioned, you must manually configure the VCPs.
QFX5100 Installation Safety Guidelines
The weight of a 1 U fully loaded QFX5100 switch chassis is approximately 30.8 lb (14 kg); the 2 U product SKU is approximately 32 lbs (14.5 kg). Observe the following guidelines for lifting and moving a QFX5100 switch:
CAUTION: If you are installing the QFX5100 switch above 60 in. (152.4 cm) from the floor, either remove the power supplies, fan modules, and any expansion modules before attempting to install the switch, or ask someone to assist you during the installation.
· Before installing a QFX5100 switch, read the guidelines in Site Preparation Checklist for a QFX5100 Device to verify that the intended site meets the specified power, environmental, and clearance requirements.
· Before lifting or moving the QFX5100 switch, disconnect all external cables.
· As when lifting any heavy object, lift most of the weight with your legs rather than your back. Keep your knees bent and your back relatively straight and avoid twisting your body as you lift. Balance the load evenly and be sure that your footing is solid.

Mount a QFX5100 Device in a Rack or Cabinet
IN THIS SECTION Before You Begin Rack Installation | 122 Four-Post Procedure | 123
You can mount all QFX5100 switches on a four post 19-in. rack or cabinet using the mounting kit provided with the device. For four post rack or cabinet installations, the mounting kit contains two front mounting rails with two matching rear mounting blades. This configuration allows either end of the switch to be mounted flush with the rack and still be adjustable for racks with different depths. (The remainder of this topic uses "rack" to mean "rack or cabinet.") The front and rear rack rails must be spaced between 28.5 in. (72.4 cm) to 31.5 in. (80 cm) front to back.
122
Before You Begin Rack Installation
Before you begin mounting a QFX5100 switch in the rack or cabinet: 1. Ensure that you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of
Electrostatic Discharge Damage. 2. Verify that the site meets the requirements described in Site Preparation Checklist for a QFX5100
Device. 3. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance,
and secure it to the building structure. 4. Read General Site Guidelines, with particular attention to QFX5100 Installation Safety Guidelines. 5. Remove the switch from the shipping carton (see Unpack a QFX5100 Device). 6. Ensure that you have the following parts and tools available to mount the switch in a rack:
· ESD grounding strap (not provided).
· Blades, rails, or brackets (provided). · For four-post installations: · One pair of rear mounting blades. These mounting blades support the rear of the chassis and must be installed (provided).
· One pair of front mounting rails. The mounting blades slide into the mounting rails to support the switch (provided).
· Screws to secure the mounting rails to the chassis (provided). · Twelve screws for 1 U chassis
· Twenty-four screws for QFX5100-96S
· Eight screws to secure the chassis and rear installation blades to the rack (not provided).
· Appropriate screwdriver for the mounting screws (not provided).
· Two power cords with plugs appropriate to your geographical location (provided).
· RJ-45 cable and RJ-45 to DB-9 serial port adapter (provided).
· Management host, such as a PC laptop, with a serial port (not provided). Optional equipment: Grounding cable kit with bracket, lug, and three nuts with integrated washers.
123
WARNING: The 1 U versions of QFX5100 switches must be supported at all four corners. Mounting the chassis using only the front brackets will damage the chassis and can result in serious bodily injury.
CAUTION: All QFX5100 switches require two people for installation, one person to lift the switch into place and another person to attach the switch to the rack. If you are installing the QFX5100 switch above 60 in. (152.4 cm) from the floor, you can remove the power supplies and fan modules to minimize the weight before attempting to install the switch.
CAUTION: If you are mounting multiple switches on a rack, mount the switch in the lowest position of the rack first. Proceed to mount the rest of the switches from the bottom to the top of the rack to minimize the risk of the rack toppling.
Four-Post Procedure
To mount the switch on four posts in a rack using the provided mounting kit: 1. Attach the ESD grounding strap to your bare wrist and to a site ESD point. 2. Decide whether the Field Replaceable Unit (FRU) end of the switch or the port end is to be placed at
the front of the rack. Position the switch in such a manner that the AIR IN labels on components are next to the cold aisle and AIR OUT labels on components are next to the hot aisle.
124 3. Align the holes in the mounting rail with the holes on the side of the chassis. See Figure 48 on page
124 through Figure 50 on page 124 for examples the proper alignment of 1 U and 2 U chassis systems. Figure 48: Attaching Mounting Rails to the QFX5100-24Q
Figure 49: Attaching Mounting Rails to the QFX5100-48S
Figure 50: Attaching Mounting Rails to the QFX5100-96S
4. Attach the mounting rail to the switch using the mounting screws (and cage nuts and washers if your rack requires them). Tighten the screws.
5. Repeats steps 4 and 5 on the opposite side of the switch.
125 6. Have one person grasp both sides of the switch, lift it, and position it in the rack so that the front
bracket is aligned with the rack holes. 7. Have a second person secure the front of the switch to the rack using four mounting screws (and
cage nuts and washers if your rack requires them.) Tighten the screws. See Figure 51 on page 125 and Figure 52 on page 125 for examples of connecting the mounting rails and blades. Figure 51: Attach 1 U Switch to Rack
Figure 52: Slide Mounting Rail onto the QFX5100-96S Rear Mounting Blade
8. Continue to support the switch while sliding the rear mounting-blades into the channel of the side mounting-rails and securing the blades to the rack. Use the four mounting screws (and cage nuts and
126 washers if your rack requires them) to attach each blade to the rack. (Use eight front-mounting screws for the QFX5100-96S.) Tighten the screws. See Figure 53 on page 126. Figure 53: Slide Mounting Blade into 1 U Mounting Rail
9. Ensure that the switch chassis is level by verifying that all the screws on the front of the rack are aligned with the screws at the back of the rack.

In a QFX Virtual Chassis, you can connect up to 10 standalone QFX5100, QFX3600, QFX3500, and EX4300 switches except EX4300-48MP and EX4300-48MP-S switches into a QFX Series Virtual Chassis and manage the interconnected switches as a single chassis. Unlike a Virtual Chassis Fabric (VCF), which is cabled in a spine and leaf topology, the QFX Virtual Chassis is cabled in a ring topology. For Virtual Chassis Fabric cabling examples, see Connecting a QFX5100 Device in a Virtual Chassis Fabric. As of Junos Release 17.3R1, you can also connect select models of the QFX5100 in the line card role in a QFX5110 Virtual Chassis. See Connecting QFX5110 and QFX5100 Members in a QFX5110 Virtual Chassis. This topic describes how to cable QFX Series switches and EX4300 switches into a QFX Virtual Chassis.
Before You Start
You configure a QFX Series Virtual Chassis by configuring the switch interfaces into Virtual Chassis ports (VCPs). VCPs connect switches together to form a Virtual Chassis, and are responsible for passing all data and control traffic between member switches in the Virtual Chassis. All non-channelized QSFP+ uplink interfaces on standalone QFX5100 switches can be configured into VCPs. All fixed SFP+ interfaces on QFX5100-96S switches can also be configured into VCPs. Use the following interfaces to create VCPs: · On QFX5100, non-channelized QSFP+ uplink interfaces. All fixed SFP+ interfaces on the
QFX5100-96S switches are also available.
· On EX4300 switches, the built-in QSFP+ ports are dedicated VCPs by default. In 48-port EX4300 switches except EX4300-48MP and EX4300-48MP-S switches, you can use the QSFP+ ports as network ports or as VCPs. You can also use the SFP+ uplink module ports as VCPs by configuring these ports as VCPs.
131
In EX4300-48MP and EX4300-48MP-S switches, you can use only the built-in QSFP+ ports as VCPs. You cannot configure the ports on the uplink module in EX4300-48MP and EX4300-48MP-S switches to Virtual Chassis ports (VCPs).
· On QFX3500 and QFX3600, all non-channelized QSFP+ and fixed SFP+ interfaces.
BEST PRACTICE: Use the 40-Gigabit QSFP+ interfaces for the VCPs.
The advantages of connecting multiple switches into a Virtual Chassis include better-managed bandwidth at a network layer, simplified configuration and maintenance because multiple devices can be managed as a single device, increased fault tolerance and high availability (HA) because a Virtual Chassis can remain active and network traffic can be redirected to other member switches when a single member switch fails, and a flatter, simplified Layer 2 network topology that minimizes or eliminates the need for loop prevention protocols such as Spanning Tree Protocol (STP).
You can increase VCP bandwidth between member switches by configuring multiple interfaces between the same two switches into VCPs. When multiple VCPs are interconnecting the same two member switches, a Link Aggregation Group (LAG) bundle is automatically formed when the VCPs are on interfaces supporting identical speeds. For instance, if you have two 40-Gigabit QSFP+ interfaces configured as VCPs between member switches, a LAG with two member links with 80 Gbps of total bandwidth is formed. 10-Gigabit SFP+ and 40-Gigabit QSFP+ interfaces configured as VCPs cannot be members of the same LAG, however. The Virtual Chassis feature is not applicable to QFX devices in a QFabric.
Virtual Chassis can be installed in a single rack, multiple racks, or in wire closets.
Valid Configurations
Valid configurations are:
· All QFX5100 membersin a ring topology this is Virtual Chassis; in a spine and leaf topology this is a Virtual Chassis Fabric (VCF). For a cabling example of spine and leaf, see Connecting a QFX5100 Device in a Virtual Chassis Fabric.
· All QFX3600 members
· All QFX3500 members
· A mixture of QFX3600 and QFX3500 members
· A mixture of QFX5100, QFX3600, and QFX3500 membersuse the QFX5100 switches as primary and backup whenever possible.
132
· A mixture of QFX5100, QFX3600, QFX3500, and EX4300 members except EX4300-48MP and EX4300-48MP-S switches. EX4300 switches as the primary or backup is not supported; use QFX5100 switches in these roles whenever possible.
An all EX4300 member is simply considered an EX4300 Virtual Chassis (see Understanding EX Series Virtual Chassis). If the QSFP+ interfaces are not available for VCP, 10-Gigbit interfaces can be used. All members of the Virtual Chassis are required to run the same Junos OS Release. You can check the version and release by issuing the show chassis version CLI command.

Connecting a QFX5100 Device in a Virtual Chassis Fabric
The role of a QFX5100 device in a VCF is dependant on the other switch models used in the VCF configuration. To understand the different hardware configurations supported, see Virtual Chassis Fabric Hardware Overview. You can install a VCF in a single rack, multiple racks, or in wire closets. You construct a QFX5100 VCF by cabling and then configuring SFP+ or QSFP+ interfaces into Virtual Chassis ports (VCPs). All nonchannelized QSFP+ uplink interfaces on QFX5100 switches can be configured into VCPs. All fixed SFP+ interfaces on QFX5100-96S switches can also be configured into VCPs.
BEST PRACTICE: Use 40-Gigabit QSFP+ ports as VCPs.

Connecting Earth Ground to a QFX5100 Device
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the QFX5100 device to earth ground before you connect it to power. For installations that require a separate grounding conductor to the chassis, you must attach a protective earthing terminal bracket on the QFX5100 device left front mounting bracket to connect to the earth ground (see Figure 67 on page 144). Before you connect earth ground to the protective earthing terminal of a QFX5100 device, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable.
CAUTION: Using a grounding cable with an incorrectly attached lug can damage the switch.
NOTE: Mount your switch in the rack or cabinet before attaching the grounding lug to the switch. See Mount a QFX5100 Device in a Rack or Cabinet.
Ensure that you have the following parts and tools available: · Protective earthing terminal bracket--This bracket attaches to the QFX5100 switch chassis through
the left front mounting bracket, providing a protective earthing terminal for the switch. · Grounding cable for your QFX5100 device--The grounding cable must be 14 AWG (2 mm²),
minimum 90° C wire, or as permitted by the local code. · Grounding lug for your grounding cable--The grounding lug required is a Panduit LCD10-10A-L or
equivalent.
143
· Two SAE 10-32 washers and screws--To attach the grounding lug to the protective earthing terminal.
· Screwdriver to attach the screws.
An AC-powered QFX5100 switch chassis gains additional grounding when you plug the power supply in the switch into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See AC Power Cord Specifications for a QFX Series Device. To connect earth ground to a QFX5100 device: 1. Attach one end of the grounding cable to an appropriate earth ground site, such as the mounting
rack. 2. Position the grounding lug over the protective earthing terminal on the side of the chassis, which is
visible through the mounting bracket.
144 3. Secure the grounding lug to the protective earthing terminal with the washers and screws. See Figure
67 on page 144 and Figure 68 on page 144. Figure 67: Connecting a Grounding Cable to a 1 U QFX5100 Device
Figure 68: Connecting a Grounding Cable to the 2 U QFX5100-96S Device
4. Dress the grounding cable and ensure that it does not touch or block access to other device components and that it does not drape where people could trip over it.

Connecting AC Power to a QFX5100 Device
Ensure that you have a power cord appropriate for your geographical location available to connect AC power to the switch. Before you begin connecting AC power to the switch: · Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD)
damage (see "Prevention of Electrostatic Discharge Damage" on page 240).
· Ensure that you have connected the switch chassis to earth ground.
CAUTION: Before you connect power to the switch, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the switch (for example, by causing a short circuit). To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the switch chassis to connect to the earth ground. For instructions on connecting earth ground, see Connecting Earth Ground to a QFX5100 Device. The switch gains additional grounding when you plug the power supply in the switch into a grounded AC power outlet by using the AC power cord appropriate for your geographical location (see AC Power Supply for a QFX5100 Device).
· Install the power supply in the chassis. For instructions on installing a power supply in a QFX5100 device, see Installing a Power Supply in a QFX5100 Device.
The QFX5100 is shipped from the factory with two power supplies. Each power supply is a hotremovable and hot-insertable field-replaceable unit (FRU) when the second power supply is installed and running. You can install replacement power supplies in the two slots next to the fan modules without powering off the switch or disrupting the switching function.
NOTE: Each power supply must be connected to a dedicated power source outlet.
To connect AC power to a QFX5100 device: 1. Attach the grounding strap to your bare wrist and to a site ESD point.
146
2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure. If only one power supply is installed, ensure a that blank cover panel is installed over the second power supply slot.
3. Locate the power cord or cords shipped with the switch; the cords have plugs appropriate for your geographical location. See "AC Power Cord Specifications for a QFX Series Device".
WARNING: Ensure that the power cord does not block access to device components or drape where people can trip on it. 4. Connect each power supply to the power sources. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.
147 5. Push the power cord retainer onto the power cord (see Figure 69 on page 147 and Figure 70 on page
147). Figure 69: Connecting an AC Power Cord to an AC Power Supply in a 1 U QFX5100 Device
1-- Power cord retainer Figure 70: Connecting an AC Power Cord to an AC Power Supply in a 2 U QFX5100 Device
6. If the AC power source outlet has a power switch, set it to the OFF (O) position. NOTE: The switch powers on as soon as power is provided to the power supply. There is no power switch on the device.
7. Insert the power cord plug into an AC power source outlet. 8. If the AC power source outlet has a power switch, set it to the ON (|) position.
148
9. Verify that the AC and DC LEDs on each power supply are lit green. If the amber fault LED is lit, remove power from the power supply, and replace the power supply (see Removing a Power Supply from a QFX5100 Device ). Do not remove the power supply until you have a replacement power supply ready: the power supplies or a blank cover panel must be installed in the switch to ensure proper airflow.
CAUTION: Replace a failed power supply with a blank panel or new power supply within 1 minute of removal to prevent chassis overheating.
CAUTION: A system reboot with Routing Engine FPGA version 7.1 might not successfully boot the Junos OS software. In case of a system reboot failure, you need to power cycle the switch. To check the current FPGA version, issue the show chassis firmware command.
Connecting DC Power to a QFX5100 Device
Before you begin connecting DC power to the switch: · Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD)
damage (see "Prevention of Electrostatic Discharge Damage" on page 240). · Ensure that you have connected the switch chassis to earth ground.
CAUTION: Before you connect power to the switch, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the switch (for example, by causing a short circuit). To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the switch chassis to connect to the earth ground. For instructions on connecting earth ground, see Connecting Earth Ground to a QFX5100 Device.
· Install the power supply in the chassis. For instructions on installing a power supply in a QFX5100 device, see Installing a Power Supply in a QFX5100 Device.
149
Ensure that you have the following parts and tools available: · DC power source cables (1416 AWG) with ring lug (Molex 190700069 or equivalent) (not provided)
· Phillips (+) screwdriver, number 2 (not provided)
· Multimeter (not provided)
The QFX5100 is shipped from the factory with two power supplies. Each power supply is a hotremovable and hot-insertable field-replaceable unit (FRU) when the second power supply is installed and running. You can install replacement power supplies in the two slots next to the fan modules without powering off the switch or disrupting the switching function.
WARNING: DC-powered QFX5100 devices are intended for installation only in a restricted access location.
NOTE: The battery returns of the DC power supply must be connected as an isolated DC return (DC-I).
To connect DC power to a QFX5100 device: 1. Attach the grounding strap to your bare wrist and to a site ESD point. 2. Verify that the DC power cables are correctly labeled before making connections to the power
supply. In a typical power distribution scheme where the return is connected to chassis ground at the battery plant, you can use a multimeter to verify the resistance of the 48V and RTN DC cables to chassis ground: · The cable with very low resistance (indicating a closed circuit) to chassis ground is positive (+)
and will be installed on the V+ (return) DC power input terminal.
· The cable with very high resistance (indicating an open circuit) to chassis ground is negative () and will be installed on the V (input) DC power input terminal.
CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and () to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the DC power input terminals on each power supply.
3. Ensure that the input circuit breaker is open so that the voltage across the DC power source cable leads is 0 V and that the cable leads do not become active while you are connecting DC power.
150
NOTE: The V+ terminals are referred to as +RTN, and V terminals are referred to as 48 V in "DC Power Wiring Sequence Warning" on page 247 and "DC Power Electrical Safety Guidelines" on page 243.
4. Ensure that the power supplies are fully inserted in the chassis. 5. Remove the terminal block cover. The terminal block cover is a piece of clear plastic that snaps into
place over the terminal block (see Figure 71 on page 151). 6. Remove the screws on the terminals using the screwdriver. Save the screws.
WARNING: Ensure that the power cables do not block access to device components or drape where people can trip on them. 7. Connect each power supply to the power sources. Secure power source cables to the power supplies by screwing the ring lugs attached to the cables to the appropriate terminals by using the screw from the terminals (see Figure 71 on page 151 and Figure 72 on page 152 ). The QFX5100 is designed to operate with a DC power supply that has a single, non-redundant, feed input. For source redundancy, two DC power supplies must be installed in QFX5100; connect source (A) to one power supply and connect source (B) to the second power supply. This configuration provides the commonly deployed A/B feed redundancy for the system. The terminal block of the power supply has four terminals labeled V+, V+, V, and V for connecting DC power source cables labeled positive (+) and negative (). The V+ terminals are shunted internally together, as are the V- terminals.
CAUTION: The connection between each power source and power supply must include a circuit breaker. Do not connect two sources to a single power supply because doing so can potentially cause circulating current in feed wires whenever there is any difference in the voltage of the two sources.
NOTE: For QFX5100-96S installations using battery backup, a single 15 A circuit breaker is recommended.
a. Secure the ring lug of the positive (+) DC power source cable to the V+ terminal on the DC power supply.
151
b. Secure the ring lug of the negative () DC power source cable to the V terminal on the DC power supply.
c. Tighten the screws on the power supply terminals until snug using the screwdriver. Do not overtighten--apply between 5 in-lb (0.56 Nm) and 6 in-lb (0.68 Nm) of torque to the screws.

5-- ESD grounding point 6-- Fault LED 7-- Output LED 8-- Input LED
CAUTION: The V+ terminals are shunted internally together, as are the Vterminals. The same polarity terminal can be wired together from the same source
152 to provide an additional current path in a higher power chassis. Do not connect the terminals to different sources. Figure 72: Securing Ring Lugs to the Terminals on the QFX5100 DC Power Supply
8. Replace the terminal block cover. 9. Close the input circuit breaker.
NOTE: The switch powers on as soon as power is provided to the power supply. There is no power switch on the device. 10. Verify that the IN and OUT LEDs on the power supply are lit green and are on steadily.
CAUTION: A system reboot with Routing Engine FPGA version 7.1 might not successfully boot the Junos OS software. In case of a system reboot failure, you need to power cycle the switch. To check the current FPGA version, issue the show chassis firmware command.

Installing an Expansion Module in a QFX5100 Device
Before you begin installing an expansion module in the switch, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage). Ensure that you have the following parts and tools available: · ESD grounding strap. If a grounding strap is not available, follow the alternative grounding method
described in Step 1 of the following procedure. · Phillips (+) screwdriver, number 2 The QFX5100-24Q device allows up to two expansion modules to be added to the port panel to increase port density. The QFX5100-24Q device holds two bays of expansion modules that can be mixed and matched as desired. The supported modules are:
169 · QFX-EM-4QEach module adds four Quad Enhanced Small Form-Factor Pluggable (QSFP+) ports.
See Figure 81 on page 169. Figure 81: QFX-EM-4Q Expansion Module
· EX4600-EM-8FEach module adds eight 10 Gigabit SFP+ ports. See Figure 82 on page 169. Figure 82: EX4600-EM-8F Expansion Module
The QFX5100-24Q device is configured for the QFX-EM-4Q by default, but any combination of the two modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-8F is inserted instead of the default QFX-EM-4Q, the new configuration causes the PFE to reboot and all of the interfaces to go down temporarily, causing a short disruption in traffic.
170
The QFX5100-24Q-AA switch supports the double-wide QFX-PFA-4Q expansion module, in addition to the QFX-EM-4Q (see Figure 81 on page 169) and the EX4600-EM-8F (see Figure 82 on page 169). The QFX-PFA-4Q module adds four 40-Gigabit Ethernet QSFP+ ports (see Figure 83 on page 170).
Figure 83: QFX-PFA-4Q Expansion Module
NOTE: When an expansion module is installed in the switch or an existing expansion module is replaced with another expansion module, the switch detects the ports on the expansion module. The switch creates the required interfaces when transceivers are installed in these ports.
To install an expansion module in a QFX5100-24Q or a QFX5100-24Q-AA device (see Figure 84 on page 171 and Figure 85 on page 172): 1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
chassis. If a grounding strap is not available, hold the expansion module in its antistatic bag in one hand and touch the exposed metallic part of the switch with the other hand to ground yourself and the component. 2. If the module slot has a cover panel on it, remove the cover panel by using the screwdriver and save it for later use. 3. Taking care not to touch module components, pins, leads, or solder connections, remove the expansion module from its bag. 4. Loosen the captive screws on the front faceplate of the expansion module by using your fingers. If you are unable to loosen the captive screws by using your fingers, use the screwdriver. 5. Using both hands, place the expansion module in the empty slot and slide it in gently until it is fully seated.
171
NOTE: After you have removed an expansion module, wait for at least 5 seconds before you install an expansion module. If you do not wait for at least 5 seconds, the interfaces on the expansion module might not come up.
6. Raise the handle and tighten the captive screws by using your fingers or the screwdriver. For the QFX5100-24Q-AA, retract the ejector handles and tighten the captive screws by using your fingers or the screwdriver (see Figure 85 on page 172). When the ST LED turns green, the expansion module is ready for use.
Figure 84 on page 171 shows how to install a QSFP+ expansion module on the port panel of a QFX5100-24Q device.
Figure 84: Installing a QFX-EM-4Q Expansion Module in a QFX5100-24Q Device

Figure 85 on page 172 shows how to install a QFX-PFA-4Q on the port panel of a QFX5100-24Q-AA switch.
Figure 85: Installing a QFX-PFA-4Q Expansion Module in a QFX5100-24Q-AA Device
NOTE: When you install the QFX-PFA-4Q expansion module in a QFX5100-24Q-AA switch and reboot the switch, the two NIC ports in the NIC inside the QFX5100-24Q-AA switch are enabled automatically. When you install other expansion modules (QFX-EM-4Q or EX4600-EM-8F), the NIC ports are enabled only when an EX4600-EM-8F is installed in slot 2 (QIC1), that is, the expansion module slot located on your right as you face the QFX5100-24Q-AA. To verify that the NIC ports are enabled, run the show interfaces terse command. For a QFX-PFA-4Q, the NIC interface names are displayed in the command output as, xe-0/0/40 and xe-0/0/41. For an EX4600-EM-8F installed in slot 2 (QIC1), the NIC interfaces are displayed as xe-0/0/24 and xe-0/0/25.
NOTE: If you have a Juniper Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/ . Failure to do so can result in significant delays if you need replacement parts. This note applies if you change the type of power supply or add a new type of expansion module. It does not apply if you replace these components with the same type of component.

Install a Transceiver
Before you install a transceiver in a device, ensure that you have taken the necessary precautions for safe handling of lasers (see "Laser and LED Safety Guidelines and Warnings" on page 228). Ensure that you have a rubber safety cap available to cover the transceiver. The transceivers for Juniper Networks devices are hot-removable and hot-insertable field-replaceable units (FRUs): You can remove and replace them without powering off the device or disrupting the device functions.
NOTE: After you insert a transceiver or after you change the media-type configuration, wait for 6 seconds for the interface to display operational commands.
NOTE: We recommend that you use only optical transceivers and optical connectors purchased from Juniper Networks with your Juniper Networks device.
CAUTION: If you face a problem running a Juniper Networks device that uses a thirdparty optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.
Figure 88 on page 178 shows how to install a QSFP+ transceiver. The procedure is the same for all types of transceivers except the QSFP28 and CFP transceivers. To install a transceiver:
CAUTION: To prevent electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the end of the transceiver.
1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the switch.
2. Remove the transceiver from its bag. 3. Check to see whether the transceiver is covered with a rubber safety cap. If it is not, cover the
transceiver with a rubber safety cap.
177
LASER WARNING: Do not leave a fiber-optic transceiver uncovered except when inserting or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light. 4. If the port in which you want to install the transceiver is covered with a dust cover, remove the dust cover and save it in case you need to cover the port later. If you are hot-swapping a transceiver, wait for at least 10 seconds after removing the transceiver from the port before installing a new transceiver. 5. Using both hands, carefully place the transceiver in the empty port. The connectors must face the chassis.
CAUTION: Before you slide the transceiver into the port, ensure that the transceiver is aligned correctly. Misalignment might cause the pins to bend, making the transceiver unusable. 6. Slide the transceiver in gently until it is fully seated. If you are installing a CFP transceiver, tighten the captive screws on the transceiver by using your fingers. 7. Remove the rubber safety cap from the transceiver and the end of the cable, and insert the cable into the transceiver.
LASER WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light. 8. If there is a cable management system, arrange the cable in the cable management system to prevent the cable from dislodging or developing stress points. Secure the cable so that it does not support its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.
178
CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

4. Cover the fiber-optic cable connector with the rubber safety cap.
How to Handle Fiber-Optic Cables
Fiber-optic cables connect to optical transceivers that are installed in Juniper Networks devices. To maintain fiber-optic cables: · When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over the transceiver
and on the end of the cable.
· Anchor fiber-optic cables to prevent stress on the connectors. When attaching a fiber-optic cable to a transceiver, be sure to secure the fiber-optic cable so that it does not support its own weight as it hangs to the floor. Never let a fiber-optic cable hang free from the connector.
· Avoid bending fiber-optic cables beyond their minimum bend radius. Bending fiber-optic cables into arcs smaller than a few inches in diameter can damage the cables and cause problems that are difficult to diagnose.
· Frequent plugging and unplugging of fiber-optic cables in and out of optical instruments can damage the instruments, which are expensive to repair. Attach a short fiber extension to the optical equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the short fiber extension, which is easier and less expensive to replace than the instruments.
· Keep fiber-optic cable connections clean. Microdeposits of oil and dust in the canal of the transceiver or cable connector can cause loss of light, reduction in signal power, and possibly intermittent problems with the optical connection. · To clean the transceiver canal, use an appropriate fiber-cleaning device such as RIFOCS Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the instructions in the cleaning kit you use.
· After cleaning the transceiver, make sure that the connector tip of the fiber-optic cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit such as the Opptex CletopS®Fiber Cleaner. Follow the instructions in the cleaning kit you use.

Alarm Types and Severity Levels
The QFX Series switches support different alarm types and severity levels. Table 36 on page 193 provides a list of alarm terms and definitions that may help you in monitoring the device.
Table 36: Alarm Terms and Definitions
Term
Definition
Alarm
Signal that alerts you to conditions that might prevent normal operation. On the device, alarm indicators might include an LCD panel and LEDs on the device. The LCD panel (if present on the device) displays the chassis alarm message count. Blinking amber or yellow LEDs indicate yellow alarm conditions for chassis components.
Alarm condition
Failure event that triggers an alarm.
194
Table 36: Alarm Terms and Definitions (Continued)
Term
Definition
Alarm severity levels
Seriousness of the alarm. The level of severity can be either major (red) or minor (yellow).
· Major (red)--Indicates a critical situation on the device that has resulted from one of the following conditions. A red alarm condition requires immediate action.
· One or more hardware components have failed.
· One or more hardware components have exceeded temperature thresholds.
· An alarm condition configured on an interface has triggered a critical warning.
· Minor (yellow or amber)--Indicates a noncritical condition on the device that, if left unchecked, might cause an interruption in service or a degradation in performance. A yellow alarm condition requires monitoring or maintenance. For example, a missing rescue configuration generates a yellow system alarm.
Alarm types
Alarms include the following types:
· Chassis alarm--Predefined alarm triggered by a physical condition on the device such as a power supply failure or excessive component temperature.
· Interface alarm--Alarm that you configure to alert you when an interface link is down. Applies to ethernet, fibre-channel, and management-ethernet interfaces. You can configure a red (major) or yellow (minor) alarm for the link-down condition, or have the condition ignored.
· System alarm--Predefined alarm that might be triggered by a missing rescue configuration, failure to install a license for a licensed software feature, or high disk usage.
195
Interface Alarm Messages
Interface alarms are alarms that you configure to alert you when an interface is down. To configure an interface link-down condition to trigger a red or yellow alarm, or to configure the linkdown condition to be ignored, use the alarm statement at the [edit chassis] hierarchy level. You can specify the ethernet, fibre-channel, or management-ethernet interface type.
NOTE: Fibre Channel alarms are valid only on QFX3500 devices.
NOTE: When red alarms or major alarms are issued on QFX5100 or EX4600 switches, the alarm LED glows amber instead of red.
By default, major alarms are configured for interface link-down conditions on the control plane and management network interfaces in a QFabric system. The link-down alarms indicate that connectivity to the control plane network is down. You can configure these alarms to be ignored using the alarm statement at the [edit chassis] hierarchy level.
NOTE: If you configure a yellow alarm on the QFX3008-I Interconnect device, it is handled as a red alarm.
Chassis Alarm Messages
Chassis alarms indicate a failure on the device or one of its components. Chassis alarms are preset and cannot be modified. Chassis alarms on QFX5100, QFX5110, QFX5210, and QFX5120 devices have two severity levels: · Major (red)--Indicates a critical situation on the device that has resulted from one of the conditions
described in Table 37 on page 196. A red alarm condition requires immediate action. · Minor (yellow)--Indicates a noncritical condition on the device that, if left unchecked, might cause an
interruption in service or degradation in performance. A yellow alarm condition requires monitoring or maintenance. Table 37 on page 196 describes the chassis alarm messages on QFX5100, QFX5110, QFX5200, QFX5210, and QFX5120 devices.

Creating an Emergency Boot Device for QFX Series Switches
Before you begin, you need to download the installation media image for your device and Junos OS release from https://www.juniper.net/customers/support/ .
201
If Junos OS on the device is damaged in some way that prevents the software from loading properly, you can use an emergency boot device to repartition the primary disk and load a fresh installation of Junos OS. Use the following procedure to create an emergency boot device.
NOTE: You can create the emergency boot device on another Juniper Networks switch or router, or any laptop or desktop PC that supports Linux. The steps you take to create the emergency boot device vary, depending on the device.
To create an emergency boot device: 1. Use FTP to copy the installation media image into the /var/tmp directory on the device. 2. Insert a USB storage device into the USB port. 3. From the Junos OS command-line interface (CLI), start the shell:
user@device> start shell % 4. Use the gunzip command to unzip the image file. 5. Switch to the root account using the su command:
% su Password: password
NOTE: The password is the root password for the device. If you logged in to the device as the root user, you do not need to perform this step.
6. Enter the following command on the device:
root@device% dd if=/var/tmp/filename of=/dev/da1 bs=1m
The device writes the installation media image to the USB storage device:
root@device% dd if=install-media-qfx-5e-15.1X53-D30.5-domestic.img of=/dev/ da0 bs=1m 1399+0 records in
202
1399+0 records out 1466957824 bytes transferred in 394.081902 secs (3722469 bytes/sec)
7. Log out of the shell:
root@device% exit % exit user@device>
Recovering the Installation Using an Emergency Boot Device
If Junos OS on your device is damaged in some way that prevents the software from loading correctly, you may need to perform a recovery installation using an emergency boot device (for example, a USB flash drive) to restore the default factory installation. Once you have recovered the software, you need to restore the device configuration. You can either create a new configuration as you did when the device was shipped from the factory, or if you saved the previous configuration, you can simply restore that file to the device. If at all possible, you should try to perform the following steps before you perform the recovery installation: 1. Ensure that you have an emergency boot device to use during the installation. See "Creating an
Emergency Boot Device for QFX Series Switches" for information on how to create an emergency boot device.
2. Copy the existing configuration in the file /config/juniper.conf.gz from the device to a remote system, such as a server, or to an emergency boot device. For extra safety, you can also copy the backup configurations (the files named /config/juniper.conf.n, where n is a number from 0 through 9) to a remote system or to an emergency boot device. You can use the system snapshot feature to complete this step. The system snapshot feature takes a "snapshot" of the files currently used to run the QFX Series switch--the complete contents of the / config and /var directories, which include the running Juniper Networks Junos OS, the active configuration, and the rescue configuration--and copies all of these files into a memory source. See "Creating a Snapshot and Using It to Boot a QFX Series Switch".
NOTE: System snapshot is not supported on QFX10000 and QFX5200 switches.
203
CAUTION: The recovery installation process completely overwrites the entire contents of the internal flash storage.
3. Copy any other stored files to a remote system as desired. To reinstall Junos OS: 1. Insert the emergency boot device into the device. 2. Power cycle the device.
The emergency boot device is detected. At this time, you can load the Junos OS from the emergency boot device onto the internal flash storage. 3. The software prompts you with the following option if you have a snapshot saved on the emergency boot device:
Junos Snapshot Installer - (c) Juniper Networks 2013 Reboot Install Junos Snapshot [14.1X53-D11_vjunos.61] Boot to host shell
[debug]
Select Install Junos Snapshot to install the snapshot. The software prompts you with the following option if you have Junos OS software from the factory installed on the emergency boot device.
Juniper Linux Installer - (c) Juniper Networks 2014 Reboot Install Juniper Linux Platform Boot to host shell [debug]
Select Install Juniper Linux Platform to install the Junos OS software from the emergency boot device. 4. The device copies the software from the emergency boot device, occasionally displaying status messages. Copying the software can take up to 12 minutes.
204
When the software is finished being copied from the emergency device to the device, the device reboots from the internal flash storage on which the software was just installed. When the reboot is complete, the device displays the Junos OS login prompt:
root@switch#
5. Create a new configuration as you did when the device was shipped from the factory, or restore the previously saved configuration file to the device.
6. Remove the emergency boot device.

Fire Safety Requirements
IN THIS SECTION Fire Suppression | 219 Fire Suppression Equipment | 219
In the event of a fire emergency, the safety of people is the primary concern. You should establish procedures for protecting people in the event of a fire emergency, provide safety training, and properly provision fire-control equipment and fire extinguishers. In addition, you should establish procedures to protect your equipment in the event of a fire emergency. Juniper Networks products should be installed in an environment suitable for electronic equipment. We recommend that fire suppression equipment be available in the event of a fire in the vicinity of the equipment and that all local fire, safety, and electrical codes and ordinances be observed when you install and operate your equipment.
Fire Suppression
In the event of an electrical hazard or an electrical fire, you should first turn power off to the equipment at the source. Then use a Type C fire extinguisher, which uses noncorrosive fire retardants, to extinguish the fire.
Fire Suppression Equipment
Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide and HalotronTM, are most effective for suppressing electrical fires. Type C fire extinguishers displace oxygen from the point of combustion to eliminate the fire. For extinguishing fire on or around equipment that draws air from the environment for cooling, you should use this type of inert oxygen displacement extinguisher instead of an extinguisher that leaves residues on equipment. Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire extinguishers). The primary ingredient in these fire extinguishers is monoammonium phosphate, which is very sticky and
220
difficult to clean. In addition, in the presence of minute amounts of moisture, monoammonium phosphate can become highly corrosive and corrodes most metals. Any equipment in a room in which a chemical fire extinguisher has been discharged is subject to premature failure and unreliable operation. The equipment is considered to be irreparably damaged.
NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher to control a fire at or near a Juniper Networks device. If a dry chemical fire extinguisher is used, the unit is no longer eligible for coverage under a service agreement.
We recommend that you dispose of any irreparably damaged equipment in an environmentally responsible manner.

Radiation from Open Port Apertures Warning
LASER WARNING: Because invisible radiation might be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. Waarschuwing Aangezien onzichtbare straling vanuit de opening van de poort kan komen als er geen fiberkabel aangesloten is, dient blootstelling aan straling en het kijken in open openingen vermeden te worden. Varoitus Koska portin aukosta voi emittoitua näkymätöntä säteilyä, kun kuitukaapelia ei ole kytkettynä, vältä säteilylle altistumista äläkä katso avoimiin aukkoihin. Avertissement Des radiations invisibles à l'il nu pouvant traverser l'ouverture du port lorsqu'aucun câble en fibre optique n'y est connecté, il est recommandé de ne pas regarder fixement l'intérieur de ces ouvertures. Warnung Aus der Port-Öffnung können unsichtbare Strahlen emittieren, wenn kein Glasfaserkabel angeschlossen ist. Vermeiden Sie es, sich den Strahlungen auszusetzen, und starren Sie nicht in die Öffnungen! Avvertenza Quando i cavi in fibra non sono inseriti, radiazioni invisibili possono essere emesse attraverso l'apertura della porta. Evitate di esporvi alle radiazioni e non guardate direttamente nelle aperture. Advarsel Unngå utsettelse for stråling, og stirr ikke inn i åpninger som er åpne, fordi usynlig stråling kan emiteres fra portens åpning når det ikke er tilkoblet en fiberkabel. Aviso Dada a possibilidade de emissão de radiação invisível através do orifício da via de acesso, quando esta não tiver nenhum cabo de fibra conectado, deverá evitar an EXposição à radiação e não deverá olhar fixamente para orifícios que se encontrarem a descoberto.
232
¡Atención! Debido a que la apertura del puerto puede emitir radiación invisible cuando no existe un cable de fibra conectado, evite mirar directamente a las aperturas para no exponerse a la radiación. Varning! Osynlig strålning kan avges från en portöppning utan ansluten fiberkabel och du bör därför undvika att bli utsatt för strålning genom att inte stirra in i oskyddade öppningar.

Before installing this equipment, users should ensure that it is permissible to connect the equipment to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the inside wiring associated with a single line individual service may be extended by means of a certified connector assembly. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations. Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.
CAUTION: Users should not attempt to make electrical ground connections by themselves, but should contact the appropriate inspection authority or an electrician, as appropriate.
Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.
