But, marking is lost when the same stream egresses out from the P router towards another PE router that has the same multicast receiver connected to it . External Interfaces The Cisco ASR 920 routers have these external physical interfaces on the front panel: Network Interfaces The network interfaces are provided through these fixed ports: · GE SFP ports--supports 100/1000 modes · GE Copper RJ-45 ports--supports 10/100/1000 operation · 10GE SFP+--supports 10G/1G mode depending on the SFP+/SFP in the network interface slot Network Timing Interfaces · BITS input or output--The BITS interfaces support clock recovery from either a T1 at 1.544 MHz or an E1 at 2.048 MHz, configurable by software. BITS interface is provided through a standard RJ-48 connector on the front panel. · 1PPS input or output and ToD input or output--This shielded RJ-45 interface is used for input or output of time-of-day (ToD) and 1PPS pulses. ToD format includes both NTP and IEEE 1588-2008 time formats. The same RS422 pins for 1PPS and TOD are shared between input and output directions. The direction for each can be independently configurable through software. External Alarm Inputs The device supports four dry contact alarm inputs through an RJ-45 jack on the front panel. The alarm condition is normally open, which indicates that no current flows through the alarm circuit, and the alarm is generated when the current is flowing. Each alarm input can be provisioned as being critical, major, or minor. Management Interfaces The Cisco ASR 920 routers have the following management interfaces: Management ENET Port A single management copper ENET port supporting 10/100/1000Base-T operation is provided at the front panel. It uses a standard RJ-45 jack. Note The management ENET port is not a data plane port. RS232 Console Port The RS232 console port provides transmission (Tx), reception (Rx), and grounding (Gnd). Cisco ASR 920 Series Aggregation Services Router Overview 7 USB Console Cisco ASR 920 Series Aggregation Services Router Overview Note The RS232 console port is enabled through only the Cisco-designed cable adapter USB type A cable to RJ-45 adapter cable. To use this port, disable the flow control on the terminal. USB Console A single USB 2.0 Type-A receptacle is provided on the front panel of the Cisco ASR 920 router for providing console access to ROMMON, Cisco IOS-XE and diagnostics. While it uses the Type-A connector, it operates as a USB peripheral only for connection to an external host computer. This interface requires the use of a Type-A to Type-A connector instead of a standard USB cable. Note Use of the USB console is mutually exclusive of the RS232 console port. This interface requires the use of a Type-A to Type-A USB cable. USB Mass Storage A single USB 2.0 Type-A receptacle is provided on the front panel of the Cisco ASR 920 router for inserting external USB mass storage devices, such as standard USB flash drives. This interface is used to load images, load or store configurations, write logs, and so on. It supports operation up to 12Mbps. Maximum memory supported in ROMmon is 8GB and in Cisco IOS is 16GB. Zero Touch Provisioning Button The Zero Touch Provisioning (ZTP) button on the front panel initiates the ZTP process on a short press of less than eight seconds. Pressing the ZTP button for more than eight seconds causes a system reset. For more information on ZTP, see Power and Status LED section. RS232 Auxiliary Console Port The RS232 Aux console port provides transmission (Tx), reception (Rx), and ground (Gnd). Note The RS232 Aux console port is enabled only through the Cisco-designed cable adapter from USB type A cable to RJ-45 adapter cable. Note This is a debug-only port. it is recommended that this port be used by field service engineers only. Power Supply and Fans The routers support AC and DC power supplies in a 1+1 redundant configuration. One AC and one DC power supply in the same router is also a supported configuration. Cisco ASR 920 Series Aggregation Services Router Overview 8 Cisco ASR 920 Series Aggregation Services Router Overview Power Supply and Fans Note The power supply units are built-in and are not modular. Table 2: Power Supply Specification Specification AC DC Voltage 100 V 240 V 24 V 60 V Current 2A through a standard C16 type receptacle 6A through a three-position terminal block Input Power 115 W (ASR-920-12CZ-A/ASR-920-4SZ-A) 105 W (ASR-920-12CZ-D/ASR-920-4SZ-D) Note This product requires surge protection as part of the building installation. To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, an external surge protective device (SPD) is required at the AC power service equipment. Note For DC systems, if a surge of more than 500 V is expected, add an appropriate external surge protective device. The routers have fixed fans are part of the system. The system is designed to operate at its maximum operating temperature of 70º C and at 65º C in case of failure of a single fan, for a maximum of four hours. The fan is not removable and in case of a failure, the system must be replaced. Caution In case of power supply or fan failure, it is highly recommended to let a Cisco technician replace the router. Table 3: Feature History Feature Name Fan Speed Update Release Information Cisco IOS XE Cupertino 17.8.1 Description This feature enables the fan speed for Cisco ASR-920-12CZ-A/D and Cisco ASR-920-4SZ-A/D to switch from default dynamic fan speed to static fan speed in the presence of smart SFP. This enables the smart SFPs to function efficiently. Use the following command to verify the fan speed configuration for the router: show platform fan-algorithm The dynamic fan-speed algorithm sets the fan speed based on the ASIC temperature. Cisco ASR 920 Series Aggregation Services Router Overview 9 Check LED Indicators Cisco ASR 920 Series Aggregation Services Router Overview Prior to Cisco IOS XE Cupertino Release 17.8.1, when the smart SFP was inserted, it would not function with the static fan-speed algorithm mode. This was resulting in the increase of the router's temperature. Starting with Cisco IOS XE Cupertino Release 17.8.1, when the smart SFP is inserted, the switch from default dynamic fan-speed algorithm to static fan-speed algorithm helps the smart SFP to function efficiently. Use the show platform fan-algorithm command to verify the fan-speed algorithm configuration for the router: Router#show platform fan-algorithm Fan Algorithm : Static Router# Check LED Indicators This section describes the different types of front panel LEDs and their behavior. PWR and STAT LEDs The PWR and STAT LEDs are available on the front panel. These LEDs provide power on the board (PWR) and overall router health (STAT) status. During power up state, these LEDs provide booting status and report errors. Note The digital code signing functionality validates the integrity and authenticity of the ROMMON image before booting it.
