Installation Guidelines

Warning

To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of: 40° C (104° F). Statement 1047

Warning

The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device. Statement 1019

Warning

This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 250 V, 15 A. Statement 1005

Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074

Caution

To ensure proper airflow it is necessary to rack the servers using rail kits. Physically placing the units on top of one another or "stacking" without the use of the rail kits blocks the air vents on top of the servers, which could result in overheating, higher fan speeds, and higher power consumption. We recommend that you mount your servers on rail kits when you are installing them into the rack because these rails provide the minimal spacing required between the servers. No additional spacing between the servers is required when you mount the units using rail kits.

Caution

Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems such as the Cisco UCS, which can have substantial current draw fluctuations from fluctuating data traffic patterns.

Initial Server Setup

Chapter 2 Installing the Server

Initial Server Setup
Connecting and Powering On the Server (Standalone Mode)

Note This section describes how to power on the server, assign an IP address, and connect to server management when using the server in standalone mode. To use the server in Cisco UCS Manager integration, specific cabling and settings are required. See Installation for Cisco UCS Integration, page D-1.
The server is shipped with these default settings:
· The NIC mode is Shared LOM EXT.
Shared LOM EXT mode enables the 1-Gb Ethernet ports and the ports on any installed Cisco virtual interface card (VIC) to access Cisco Integrated Management Interface (Cisco IMC). If you want to use the 10/100/1000 dedicated management ports to access Cisco IMC, you can connect to the server and change the NIC mode as described in Step 1 of the following procedure.
· The NIC redundancy is active-active. All Ethernet ports are utilized simultaneously.
· DHCP is enabled.
· IPv4 is enabled.
There are two methods for connecting to the system for initial setup:
· Local setup--Use this procedure if you want to connect a keyboard and monitor to the system for setup. This procedure can use a KVM cable (Cisco PID N20-BKVM) or the ports on the rear of the server. See Local Connection Procedure, page 2-10.
· Remote setup--Use this procedure if you want to perform setup through your dedicated management LAN. See Remote Connection Procedure, page 2-11.

Note To configure the system remotely, you must have a DHCP server on the same network as the system. Your DHCP server must be preconfigured with the range of MAC addresses for this server node. The MAC address is printed on a label that is on the pull-out asset tag on the front panel (see Figure 1-1 or Figure 1-2). This server node has a range of six MAC addresses assigned to the Cisco IMC. The MAC address printed on the label is the beginning of the range of six contiguous MAC addresses.

Local Connection Procedure

Step 1 Step 2

Attach a power cord to each power supply in your server, and then attach each power cord to a grounded AC power outlet. See Power Specifications, page A-3 for power specifications.
Wait for approximately two minutes to let the server boot in standby power during the first bootup.
You can verify system power status by looking at the system Power Status LED on the front panel (see External Features Overview, page 1-1). The system is in standby power mode when the LED is amber.
Connect a USB keyboard and VGA monitor to the server using one of the following methods:
· Connect a USB keyboard and VGA monitor to the corresponding connectors on the rear panel (see External Features Overview, page 1-1).

Chapter 2 Installing the Server

Cisco IMC Configuration Utility Setup

The following procedure is performed after you connect to the system and open the Cisco IMC Configuration Utility.

Step 1 Step 2

Set NIC mode and NIC redundancy:
a. Set the NIC mode to choose which ports to use to access Cisco IMC for server management (see Figure 1-3 on page 1-4 for identification of the ports):
· Shared LOM EXT (default)--This is the shared LOM extended mode, the factory-default setting. With this mode, the Shared LOM and Cisco Card interfaces are both enabled.
In this mode, DHCP replies are returned to both the shared LOM ports and the Cisco card ports. If the system determines that the Cisco card connection is not getting its IP address from a Cisco UCS Manager system because the server is in standalone mode, further DHCP requests from the Cisco card are disabled. Use the Cisco Card NIC mode if you want to connect to Cisco IMC through a Cisco card in standalone mode.
· Shared LOM--The 1-Gb Ethernet ports are used to access Cisco IMC. You must select a NIC redundancy and IP setting.
· Dedicated--The dedicated management port is used to access Cisco IMC. You must select a NIC redundancy and IP setting.
· Cisco Card--The ports on an installed Cisco UCS virtual interface card (VIC) are used to access the Cisco IMC. You must select a NIC redundancy and IP setting.
See also the required VIC Slot setting below.
· VIC Slot--If you use the Cisco Card NIC mode, you must select this setting to match where your VIC is installed. The choices are Riser1, Riser2, or Flex-LOM (the mLOM slot).
­ If you select Riser1, slot 1 is used.
­ If you select Riser2, slot 2 is used.
­ If you select Flex-LOM, you must use an mLOM-style VIC in the mLOM slot.
b. Use this utility to change the NIC redundancy to your preference. This server has three possible NIC redundancy settings:
­ None--The Ethernet ports operate independently and do not fail over if there is a problem. This setting can be used only with the Dedicated NIC mode.
­ Active-standby--If an active Ethernet port fails, traffic fails over to a standby port.
­ Active-active--All Ethernet ports are utilized simultaneously. The Shared LOM EXT mode can have only this NIC redundancy setting. Shared LOM and Cisco Card modes can have both Active-standby and Active-active settings.
Choose whether to enable DHCP for dynamic network settings, or to enter static network settings.

Note Before you enable DHCP, you must preconfigure your DHCP server with the range of MAC addresses for this server. The MAC address is printed on a label on the rear of the server. This server has a range of six MAC addresses assigned to Cisco IMC. The MAC address printed on the label is the beginning of the range of six contiguous MAC addresses.

This server has the following NIC mode settings that you can choose from: · Shared LOM EXT (default)--This is the Shared LOM extended mode, the factory-default setting.
With this mode, the shared LOM and Cisco Card interfaces are both enabled. In this mode, DHCP replies are returned to both the shared LOM ports and the Cisco card ports. If the system determines that the Cisco card connection is not getting its IP address from a Cisco UCS Manager system because the server is in standalone mode, further DHCP requests from the Cisco card are disabled. If the system determines that the Cisco card connection is getting its IP address from a Cisco UCS Manager system, the reply has parameters that automatically move the server to UCSM mode. · Dedicated--The dedicated management port is used to access Cisco IMC. You must select a NIC redundancy and IP setting. · Shared LOM--The 1-Gb Ethernet ports are used to access Cisco IMC. You must select a NIC redundancy and IP setting. · Cisco Card--The ports on an installed Cisco UCS virtual interface card (VIC) are used to access Cisco IMC. You must select a NIC redundancy and IP setting. See also the required VIC Slot setting below. · VIC Slot--If you use the Cisco Card NIC mode, you select this setting to match where your VIC is installed. The choices are Riser1, Riser2, or Flex-LOM (the mLOM slot). ­ If you select Riser1, slot 1 is used. ­ If you select Riser2, slot 2 is used. ­ If you select Flex-LOM, you must use an mLOM-style VIC in the mLOM slot.
NIC Redundancy
This server has the following NIC redundancy settings that you can choose from: ­ None--The Ethernet ports operate independently and do not fail over if there is a problem. This setting can be used only with the Dedicated NIC mode. ­ Active-standby--If an active Ethernet port fails, traffic fails over to a standby port. ­ Active-active--All Ethernet ports are utilized simultaneously. Shared LOM EXT mode can have only this NIC redundancy setting. Shared LOM and Cisco Card modes can have both Active-standby and Active-active settings. The active/active setting uses Mode 5 or Balance-TLB (adaptive transmit load balancing). This is channel bonding that does not require any special switch support. The outgoing traffic is distributed according to the current load (computed relative to the speed) on each slave. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave.

Preparing for Server Component Installation
This section describes how to prepare for component installation, and it includes the following topics: · Required Equipment, page 3-8 · Shutting Down and Powering Off the Server, page 3-8 · Removing and Replacing the Server Top Cover, page 3-9 · Serial Number Location, page 3-10 · Hot-Swap or Hot-Plug Replacement, page 3-10

Required Equipment
The following equipment is used to perform the procedures in this chapter: · Number 2 Phillips-head screwdriver · Electrostatic discharge (ESD) strap or other grounding equipment such as a grounded mat

Shutting Down and Powering Off the Server
The server can run in two power modes: · Main power mode--Power is supplied to all server components and any operating system on your
drives can run. · Standby power mode--Power is supplied only to the service processor and the cooling fans and it
is safe to power off the server from this mode. You can invoke a graceful shutdown or a hard shutdown by using either of the following methods: · Use the Cisco IMC management interface. · Use the Power button on the server front panel. To use the Power button, follow these steps:

Step 1 Step 2

Check the color of the Power Status LED (see the "Front Panel LEDs" section on page 3-2). · Green--The server is in main power mode and must be shut down before it can be safely powered
off. Go to Step 2. · Amber--The server is already in standby mode and can be safely powered off. Go to Step 3. Invoke either a graceful shutdown or a hard shutdown:

Caution To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown of the operating system.

Step 3

· Graceful shutdown--Press and release the Power button. The operating system performs a graceful shutdown and the server goes to standby mode, which is indicated by an amber Power Status LED.
· Emergency shutdown--Press and hold the Power button for 4 seconds to force the main power off and immediately enter standby mode.
Disconnect the power cords from the power supplies in your server to completely power off the server.

Warning

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029

Caution When handling server components, wear an ESD strap to avoid damage.

Tip You can press the unit identification button on the front panel or rear panel to turn on a flashing unit identification LED on the front and rear panels of the server. This button allows you to locate the specific server that you are servicing when you go to the opposite side of the rack. You can also activate these LEDs remotely by using the Cisco IMC interface.

Replacing SAS/SATA Hard Drives or Solid State Drives
This section includes the following information: · SAS/SATA Drive Population Guidelines, page 3-13 · Replacing a SAS/SATA Drive, page 3-14

SAS/SATA Drive Population Guidelines
The server has two different drive backplane options: · The small form factor (SFF), 8-drives version can hold up to eight 2.5-inch SAS/SATA hard drives
or solid state drives. SAS/SATA drives are hot-swappable. · The large form factor (LFF), 4-drives version can hold up to four 3.5-inch SAS/SATA hard drives. The drive-bay numbering is shown in Figure 3-6.

Observe these drive population guidelines for optimum performance:
· When populating drives, add drives to the lowest-numbered bays first.
· Keep an empty drive blanking tray in any unused bays to ensure proper airflow.
· You can mix SAS/SATA hard drives and SAS/SATA SSDs in the same server (the LFF version of the server does not support SSDs). However, you cannot configure a logical volume (virtual drive) that contains a mix of hard drives and SSDs. That is, when you create a logical volume, it must contain all SAS/SATA hard drives or all SAS/SATA SSDs.

NVMe PCIe SSD Population Guidelines
The SFF 8-drive version of the server supports up to two NVMe PCIe solid state drives (SSDs), in drive bays 1 and 2 only.
NVME PCIe SSD Requirements and Restrictions
Observe these requirements for NVMe PCIe SSDs: · The SFF, 8-drives version of the server. · PCIe riser version 2B (UCSC-PCI-2B-220M4), with bundled cables. This version of the riser has
cable connectors for the PCIe cables that connect to the drive backplane. · The server must have two CPUs. PCIe riser 2 is not available in a single-CPU system.

Observe these restrictions for NVMe PCIe SSDs:
· You cannot boot from an NVMe PCIe SSD.
· You cannot control NVMe PCIe SSDs with a SAS RAID controller because they communicate with the server via the PCIe bus.

Caution

NVMe PCIe SSDs are hot-pluggable, which means that you must shut down the drive before removal, but you do not have to fully power off the server. To replace a SAS/SATA drive, see Replacing a SAS/SATA Drive, page 3-14.

Replacing an NVMe PCIe SSD
For information about drive tray LEDs, see Front Panel LEDs, page 3-2.

Step 1

Remove an existing NVMe PCIe SSD: a. Shut down the NVMe PCIe SSD. Use your operating system interface to shut down the drive, and
then observe the drive-tray LED: ­ Green--The drive is in use and functioning properly. Do not remove. ­ Green, blinking--the driver is unloading following a shutdown command. Do not remove. ­ Off--The drive is not in use and can be safely removed. b. Press the release button on the face of the drive tray. See Figure 3-8. c. Grasp and open the ejector lever and then pull the drive tray out of the slot. d. If you are replacing an existing SSD, remove the four drive tray screws that secure the SSD to the tray and then lift the SSD out of the tray.

DIMM Population Rules
Observe the following guidelines when installing or replacing DIMMs: Observe the following guidelines when installing or replacing DIMMs: · Each CPU supports four memory channels.
­ CPU1 supports channels A, B, C, and D. ­ CPU2 supports channels E, F, G, and H. · Each channel has three DIMM sockets (for example, channel A = slots A1, A2, and A3). ­ A channel can operate with one, two, or three DIMMs installed. ­ If a channel has only one DIMM, populate slot 1 first (the blue slot). · When both CPUs are installed, populate the DIMM sockets of each CPU identically. ­ Fill blue #1 slots in the channels first: A1, E1, B1, F1, C1, G1, D1, H1 ­ Fill black #2 slots in the channels second: A2, E2, B2, F2, C2, G2, D2, H2 ­ Fill white #3 slots in the channels third: A3, E3, B3, F3, C3, G3, D3, H3 · Any DIMM installed in a DIMM socket for which the CPU is absent is not recognized. In a single-CPU configuration, populate the channels for CPU1 only (A, B, C, D). · Memory mirroring reduces the amount of memory available by 50 percent because only one of the two populated channels provides data. When memory mirroring is enabled, DIMMs must be installed in sets of 4, 6, or 8 as described in Memory Mirroring and RAS, page 3-25. · Observe the DIMM mixing rules shown in Table 3-4.

· You can mix different capacity DIMMs in the same channel (for example, A1, A2, A3).

· You can mix different capacity DIMMs in the same bank. However, for optimal performance DIMMs in the same bank (for example, A1, B1, C1, D1) should have the same capacity.

installed in the bank.

DIMM Type: RDIMMs or LRDIMMs

You cannot mix DIMM types in a channel. You cannot mix DIMM types in a bank.

Memory Mirroring and RAS
The Intel E5-2600 CPUs within the server support memory mirroring only when an even number of channels are populated with DIMMs. If one or three channels are populated with DIMMs, memory mirroring is automatically disabled. Furthermore, if memory mirroring is used, DRAM size is reduced by 50 percent for reasons of reliability.
For details on populating recommended memory mirroring configurations, see the specification sheet for the server:
· Cisco UCS C220 M4 High Density Rack Server (Small Form-Factor Disk Drive Model) Specification Sheet
· Cisco UCS C220 M4 High Density Rack Server (Large Form-Factor Disk Drive Model) Specification Sheet
Lockstep Channel Mode
When you enable lockstep channel mode, each memory access is a 128-bit data access that spans four channels.
Lockstep channel mode requires that all four memory channels on a CPU must be populated identically with regard to size and organization. DIMM socket populations within a channel (for example, A1, A2, A3) do not have to be identical but the same DIMM slot location across all four channels must be populated the same.
For example, DIMMs in sockets A1, B1, C1, and D1 must be identical. DIMMs in sockets A2, B2, C2, and D2 must be identical. However, the A1-B1-C1-D1 DIMMs do not have to be identical with the A2-B2-C2-D2 DIMMs.

DIMM Replacement Procedure
This section includes the following topics: · Identifying a Faulty DIMM, page 3-26 · Replacing DIMMs, page 3-26
Identifying a Faulty DIMM
Each DIMM socket has a corresponding DIMM fault LED, directly in front of the DIMM socket. See Figure 3-3 for the locations of these LEDs. The LEDs light amber to indicate a faulty DIMM. To operate these LEDs from the supercap power source, remove AC power cords and then press the unit identification button. See also Internal Diagnostic LEDs, page 3-7.
Replacing DIMMs

Step 1

Remove the DIMM that you are replacing:
a. Power off the server as described in the Shutting Down and Powering Off the Server, page 3-8. b. Slide the server out the front of the rack far enough so that you can remove the top cover. You might
have to detach cables from the rear panel to provide clearance.

Caution If you cannot safely view and access the component, remove the server from the rack.

Step 2

c. Remove the top cover as described in Removing and Replacing the Server Top Cover, page 3-9. d. Identify the faulty DIMM by observing the DIMM slot fault LEDs on the motherboard. e. Open the ejector levers at both ends of the DIMM slot, and then lift the DIMM out of the slot. Install a new DIMM:

Note Before installing DIMMs, see the population guidelines: Memory Performance Guidelines and Population Rules, page 3-23.
f. Align the new DIMM with the empty slot on the motherboard. Use the alignment key in the DIMM slot to correctly orient the DIMM.
g. Push down evenly on the top corners of the DIMM until it is fully seated and the ejector levers on both ends lock into place.
h. Replace the top cover. i. Replace the server in the rack, replace cables, and then power on the server by pressing the Power

The minimum software and firmware versions required for the server to support Intel v4 CPUs are as follows:

Table 3-5

Minimum Requirements For Intel Xeon v4 CPUs

Software or Firmware Server CIMC Server BIOS Cisco UCS Manager (UCSM-managed system only)

Minimum Version 2.0(10) 2.0(10) 3.1(0)

Do one of the following actions:
· If your server's firmware and/or Cisco UCS Manager software are already at the required levels shown in Table 3-5, you can replace the CPU hardware by using the procedure in this section.
· If your server's firmware and/or Cisco UCS Manager software is earlier than the required levels, use the instructions in the Cisco UCS C-Series Servers Upgrade Guide for Intel Xeon v4 CPUs to upgrade your software. After you upgrade the software, return to the procedure in this section as directed to replace the CPU hardware.

CPU Configuration Rules
This server has two CPU sockets. Each CPU supports four DIMM channels (12 DIMM slots). See Figure 3-14. · The server can operate with one CPU or two identical CPUs installed. · The minimum configuration is that the server must have at least CPU1 installed. Install CPU1 first,
and then CPU2. · The following restrictions apply when using a single-CPU configuration:
­ The maximum number of DIMMs is 12 (only CPU1 channels A, B, C, and D). ­ PCIe riser 2/slot 2 is unavailable.

CPU Replacement Procedure

Caution

CPUs and their motherboard sockets are fragile and must be handled with care to avoid damaging pins during installation. The CPUs must be installed with heatsinks and their thermal pads to ensure proper cooling. Failure to install a CPU correctly might result in damage to the server.

Note This server uses the new independent loading mechanism (ILM) CPU sockets, so no Pick-and-Place tools are required for CPU handling or installation. Always grasp the plastic frame on the CPU when handling.

Step 1 Step 2

Power off the server as described in Shutting Down and Powering Off the Server, page 3-8.
Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution If you cannot safely view and access the component, remove the server from the rack.

Step 3 Step 4 Step 5

Remove the top cover as described in Removing and Replacing the Server Top Cover, page 3-9.
Remove the plastic air baffle that sits over the CPUs. Remove the heatsink that you are replacing. Use a Number 2 Phillips-head screwdriver to loosen the four captive screws that secure the heatsink and then lift it off of the CPU.

Note Alternate loosening each screw evenly to avoid damaging the heatsink or CPU.

Step 6

Step 10 Step 11 Step 12

Replace the air baffle. Replace the top cover. Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.

Additional CPU-Related Parts to Order with RMA Replacement Motherboards
When a return material authorization (RMA) of the motherboard or CPU is done on a Cisco UCS C-series server, additional parts might not be included with the CPU or motherboard spare bill of materials (BOM). The TAC engineer might need to add the additional parts to the RMA to help ensure a successful replacement.
· Scenario 1--You are reusing the existing heatsinks:
­ Heat sink cleaning kit (UCSX-HSCK=)
­ Thermal grease kit for C240 M4 (UCS-CPU-GREASE3=)
· Scenario 2--You are replacing the existing heatsinks:
­ Heat sink (UCSC-HS-C220M4=)
­ Heat sink cleaning kit (UCSX-HSCK=)
A CPU heatsink cleaning kit is good for up to four CPU and heatsink cleanings. The cleaning kit contains two bottles of solution, one to clean the CPU and heatsink of old thermal interface material and the other to prepare the surface of the heatsink.
New heatsink spares come with a pre-applied pad of thermal grease. It is important to clean the old thermal grease off of the CPU prior to installing the heatsinks. Therefore, when you are ordering new heatsinks, you must order the heatsink cleaning kit.

1. All slots can be enabled to provide more than the default 25 W power draw for higher performance on some cards. See Enabling Higher Power-Draw for Fusion ioDrive3 Cards, page 3-50.
2. A rear-panel tab adapter is required to fit the half-height cards in full-height slots.

Enabling Higher Power-Draw for Fusion ioDrive3 Cards
Some Fusion ioDrive3 accelerator cards such as the 5800 GB card draw 25 W by default but can achieve higher performance when the PCIe slot is configured to provide more than 25 W for the device. PCIe slots that can be configured to support more than 25 W power draw: All. All slots can support the higher device power draw of 55 W (75 W maximum) when configured with the override parameter in the IO Accelerator VSL software.

Note See the Cisco UCS power calculator to determine the total power draw for your exact server configuration: http://www.cisco.com/assets/cdc_content_elements/flash/dataCenter/cisco_ucs_power_calculator/
The override parameter in the IO Accelerator VSL software (in the /usr/modprove.d/iomemory-vsl.conf file) overrides the setting that prevents devices from drawing more than 25 W from the PCIe slot. The parameter is enabled by device, by using the device serial numbers.

Note The override parameter is a setting for the IO Accelerator VSL software by server and is not stored in the device. When moved to a new server, the device defaults to the 25 W power limit until an external power cable is added or the override parameter is enabled for that device in the new server.

Step 1

Determine the serial number of the installed Fusion device by using the fio-status command in the IO Accelerator VSL software. Sample output is shown here:
fio-status Adapter: Dual Controller Adapter

In this example, 1149D0969 is the adapter serial number. If you have multiple Fusion ioDrive3 devices installed in your system, use the fio-beacon command to verify where each device is physically located.

Note There is also a serial number label on the card, but we recommend that you use the fio-status command to confirm the serial number is an adapter serial number (FIO SN in the sample output above).

Step 2 Step 3

Set the override parameter by editing the /usr/modprove.d/iomemory-vsl.conf file, which is installed when you install the device drivers. Change the value for the external_power_override parameter, where the <value> for this parameter is a comma-separated list of adapter serial numbers.
options iomemory-vsl external_power_override=<value>
For example:
options iomemory-vsl external_power_override=1149D0969,1159E0972
Reboot the server or unload and then load the drivers to enforce the parameter changes.

Installing Multiple PCIe Cards and Resolving Limited Resources
When a large number of PCIe add-on cards are installed in the server, the system might run out of the following resources required for PCIe devices: · Option ROM memory space · 16-bit I/O space The topics in this section provide guidelines for resolving the issues related to these limited resources: · Resolving Insufficient Memory Space to Execute Option ROMs, page 3-51 · Resolving Insufficient 16-Bit I/O Space, page 3-52

Resolving Insufficient Memory Space to Execute Option ROMs

The system has very limited memory to execute PCIe legacy option ROMs, so when a large number of PCIe add-on cards are installed in the server, the system BIOS might not able to execute all of the option ROMs. The system BIOS loads and executes the option ROMs in the order that the PCIe cards are enumerated (slot 1, slot 2, slot 3, and so on).

If the system BIOS does not have sufficient memory space to load any PCIe option ROM, it skips loading that option ROM, reports a system event log (SEL) event to the Cisco IMC controller and reports the following error in the Error Manager page of the BIOS Setup utility:

ERROR CODE SEVERITY

146

INSTANCE N/A

DESCRIPTION PCI out of resources error. Major severity requires user intervention but does not prevent system boot.

OL-32473-01

Installing or Replacing Server Components

Chapter 3 Maintaining the Server

To resolve this issue, disable the Option ROMs that are not needed for system booting. The BIOS Setup Utility provides the setup options to enable or disable the Option ROMs at the PCIe slot level for the PCIe expansion slots and at the port level for the onboard NICs. These options can be found in the BIOS Setup Utility Advanced PCI Configuration page.
· Guidelines for RAID controller booting
If the server is configured to boot primarily from RAID storage, make sure that the option ROMs for the slots where your RAID controllers installed are enabled in the BIOS, depending on your RAID controller configuration.
If the RAID controller does not appear in the system boot order even with the option ROMs for those slots enabled, the RAID controller option ROM might not have sufficient memory space to execute. In that case, disable other option ROMs that are not needed for the system configuration to free up some memory space for the RAID controller option ROM.
· Guidelines for onboard NIC PXE booting
If the system is configured to primarily perform PXE boot from onboard NICs, make sure that the option ROMs for the onboard NICs to be booted from are enabled in the BIOS Setup Utility. Disable other option ROMs that are not needed to create sufficient memory space for the onboard NICs.
Resolving Insufficient 16-Bit I/O Space
The system has only 64 KB of legacy 16-bit I/O resources available. This 64 KB of I/O space is divided between the CPUs in the system because the PCIe controller is integrated into the CPUs. This server BIOS has the capability to dynamically detect the 16-bit I/O resource requirement for each CPU and then balance the 16-bit I/O resource allocation between the CPUs during the PCI bus enumeration phase of the BIOS POST.
When a large number of PCIe cards are installed in the system, the system BIOS might not have sufficient I/O space for some PCIe devices. If the system BIOS is not able to allocate the required I/O resources for any PCIe devices, the following symptoms have been observed:
· The system might get stuck in an infinite reset loop.
· The BIOS might appear to hang while initializing PCIe devices.
· The PCIe option ROMs might take excessive time to complete, which appears to lock up the system.
· PCIe boot devices might not be accessible from the BIOS.
· PCIe option ROMs might report initialization errors. These errors are seen before the BIOS passes control to the operating system.
· The keyboard might not work.
To work around this problem, rebalance the 16-bit I/O load using the following methods:
1. Physically remove any unused PCIe cards.
2. If the system has one or more Cisco virtual interface cards (VICs) installed, disable the PXE boot on the VICs that are not required for the system boot configuration by using the Network Adapters page in the Cisco IMC Web UI to free up some 16-bit I/O resources. Each VIC uses a minimum 16 KB of 16-bit I/O resource, so disabling PXE boot on Cisco VICs would free up some 16-bit I/O resources that can be used for other PCIe cards that are installed in the system.

Installing and Enabling a Trusted Platform Module (TPM)

The trusted platform module (TPM) is a small circuit board that attaches to a motherboard socket. The socket location is on the motherboard between the power supplies and PCIe riser 2 (see Figure 3-29).

TPM 2.0 Considerations
Trusted platform module (TPM) version 2.0 is supported on Intel v3- or Intel v4-based platforms. If there is an existing TPM 1.2 installed in the server, you cannot upgrade to TPM 2.0. If there is no existing TPM in the server, you can install TPM 2.0. You must first upgrade to Intel v4 code, regardless of whether the installed CPU is Intel v3 or v4. TPM 2.0 requires Intel v4 code or later.

Caution

If your Intel v3 or Intel v4 system is currently supported and protected by TPM version 2.0, a potential security exposure might occur if you downgrade the system software and BIOS to a version earlier than those shown in Table 3-10.

Note If the TPM 2.0 becomes unresponsive, reboot the server.

Replacing an mLOM Card
The server can use a modular LOM (mLOM) card to provide additional rear-panel connectivity. The mLOM card socket remains powered when the server is in 12 V standby power mode and it supports the network communications services interface (NCSI) protocol.

Step 1

Remove any existing mLOM card (or a blanking panel):
a. Power off the server as described in Shutting Down and Powering Off the Server, page 3-8. b. Slide the server out the front of the rack far enough so that you can remove the top cover. You might
have to detach cables from the rear panel to provide clearance.

Caution If you cannot safely view and access the component, remove the server from the rack.

Step 2
Step 3 Step 4
Step 5 Step 6 Step 7

c. Remove the top cover as described in Removing and Replacing the Server Top Cover, page 3-9.
See the location of the mLOM socket in Figure 3-30. You might have to remove PCIe riser 1 and the Cisco modular RAID controller riser to provide clearance.
· If there is no card in PCIe riser 1 or the RAID card riser, you can access the mLOM socket. Continue with Step 3.
· If there is a card in PCIe riser 1 or the RAID card riser, remove those risers to provide clearance. See Replacing a PCIe Riser Assembly, page 3-44 and Replacing a Cisco Modular RAID Controller Card, page 3-35 for instructions.
Loosen the single thumbscrew that secures the mLOM card to the chassis floor and then slide the mLOM card horizontally to disengage its connector from the motherboard socket.
Install a new mLOM card:
a. Set the mLOM card on the chassis floor so that its connector is aligned with the motherboard socket and its thumbscrew is aligned with the standoff on the chassis floor.
b. Push the card's connector into the motherboard socket horizontally.
c. Tighten the thumbscrew to secure the card to the chassis floor.
If you removed PCIe riser 1 or the RAID card riser, return them to the server. See Replacing a PCIe Riser Assembly, page 3-44 or Replacing a Cisco Modular RAID Controller Card, page 3-35 for instructions.
Replace the top cover.
Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.

Replacing Power Supplies

Chapter 3 Maintaining the Server

The server can have one or two power supplies. When two power supplies are installed they are redundant as 1+1. · Replacing an AC Power Supply, page 3-60 · Installing a DC Power Supply (UCSC-PSUV2-1050DC), page 3-61 · Installation Grounding, page 3-62 · See also Power Specifications, page A-3 for more information about the power supplies. · See also Rear Panel LEDs and Buttons, page 3-5 for information about the power supply LEDs.

Note If you have ordered a server with power supply redundancy (two power supplies), you do not have to power off the server to replace power supplies because they are redundant as 1+1.

Note Do not mix power supply types or wattages in the server.

Replacing an AC Power Supply

Step 1 Step 2

Remove the power supply that you are replacing or a blank panel from an empty bay (see Figure 3-31): a. Perform one of the following actions:
­ If your server has only one power supply, shut down and power off the server as described in the "Shutting Down and Powering Off the Server" section on page 3-8.
­ If your server has two power supplies, you do not have to shut down the server. b. Remove the power cord from the power supply that you are replacing. c. Grasp the power supply handle while pinching the release lever toward the handle. d. Pull the power supply out of the bay. Install a new power supply: a. Grasp the power supply handle and insert the new power supply into the empty bay. b. Push the power supply into the bay until the release lever locks. c. Connect the power cord to the new power supply. d. If you shut down the server, press the Power button to return the server to main power mode.

Installation Grounding
AC power supplies have internal grounding and so no additional grounding is required when the supported AC power cords are used. When using a DC power supply, additional grounding of the server chassis to the earth ground of the rack is available. A screw hole for use with your grounding lug and grounding wire are supplied on the chassis rear panel.
Note The grounding point on the chassis is sized for a single #10-32 screw. A lock-washer is required to secure the lug to the chassis. You must provide your own screw with lock-washer, grounding lug, and grounding wire. The grounding lug must be a single-hole lug that fits a #10-32 screw and 14 AWG wire. The grounding cable that you provide must be 14 AWG (2 mm), minimum 60° C wire, or as permitted by the local code.
See Figure 3-31 for the location of the grounding lug screw-hole on the chassis rear panel.

Appendix C RAID Controller Considerations

RAID Card Firmware Compatibility

RAID Card Firmware Compatibility
Firmware on the RAID controller must be verified for compatibility with the current Cisco IMC and BIOS versions that are installed on the server. If not compatible, upgrade or downgrade the RAID controller firmware accordingly using the Host Upgrade Utility (HUU) for your firmware release to bring it to a compatible level. See the HUU guide for your Cisco IMC release for instructions on downloading and using the utility to bring server components to compatible levels: HUU Guides
Write-Cache Policy for Cisco 12G SAS Modular RAID Controller
For this server and other Cisco Generation M4 servers, the default write-cache policy for the Cisco Modular RAID controller is Write Through (irrespective of the presence of a charged Supercap power module or "good BBU"). This utilizes the optimal performance characteristics of the controller. If you have Cisco IMC 2.0(5) or later firmware installed to the M4 server, the write policy can be set to Write Back, if preferred. You can set the write policy using the following methods: · For standalone servers, use the Cisco IMC interface to set Virtual Drive Properties > Write Policy. See
the "Managing Storage Adapters" section in your Cisco IMC Configuration Guide. Cisco IMC GUI and CLI Configuration Guides · For Cisco UCS-integrated servers, use the Cisco UCS Manager interface to set the write-cache policy as part of virtual drive configuration in your storage profile. Cisco UCS Manager Configuration Guides · Use the LSI Option ROM Configuration Utility.

Appendix C RAID Controller Considerations

Cisco UCS SAS 9300-8e HBA Considerations
This section contains the following topics: · Mixing Rules, page C-4 · Bad Drive and Predictive Failure Behavior, page C-4 · Setting the Preferred Boot Device, page C-4

Mixing Rules
Mixing the Cisco UCS 9300-8e HBA in the same server as the Cisco UCS 12G SAS Modular HBA requires the following firmware levels: · Cisco IMC/BIOS 2.0(8) or later · Cisco UCS Manager 2.2(6) or later (for integrated servers only)

Bad Drive and Predictive Failure Behavior
The bad drive and predictive failure behavior for the Cisco UCS SAS 9300-e HBA cards is different than that for LSI MegaRAID cards. The list below compares behavior for these HBA cards and LSI MegaRAID cards.
· Bad/invalid/0MB drive handling:
­ MegaRAID: The bad drive is marked BAD in the GUI/CLI interfaces and the fault LED on the drive is solid amber.
­ HBA: The bad drive is not shown in the GUI/CLI and there is no LED indication.
· Drive predictive failure:
­ MegaRAID: If the drive is part of a RAID volume with a spare, the software performs an auto-copy backup and then marks the drive failed/BAD with the fault LED on the drive solid amber.
­ HBA: There is no error handling and there is no LED indication. The operating system must handle the fault.

Setting the Preferred Boot Device
Currently, the boot device order for these HBAs does not map to a physical slot as seen in the Boot Option dialog of the server BIOS Setup Utility. This makes it difficult to differentiate between multiple devices.
Use the following procedure to select the preferred boot device in the LSI BIOS CU SAS Topology screen. When you select the preferred boot device in the BIOS CU SAS Topology screen, it is displayed at the top of the list in the server BIOS Setup Utility Boot Option dialog, making it easy to identify.

Step 1 Step 2

In the LSI SAS BIOS CU, navigate to the SAS Topology screen.
Press Alt+B to select or deselect a device as the preferred boot device. On this screen, you can identify the device by slot number.

Mixing Drive Types in RAID Groups

Appendix C RAID Controller Considerations

Mixing Drive Types in RAID Groups

Table C-2 lists the technical capabilities for mixing hard disk drive (HDD) and solid state drive (SSD) types in a RAID group. However, see the recommendations that follow for the best performance.

Table C-2

Drive Type Mixing in RAID Groups

Mix of Drive Types in RAID Group SAS HDD + SATA HDD SAS SSD + SATA SSD HDD + SSD

Allowed? Yes Yes No

Mixing Drive Types in RAID Groups
For the best performance, follow these guidelines: · Use either all SAS or all SATA drives in a RAID group. · Use the same capacity for each drive in the RAID group. · Never mix HDDs and SSDs in the same RAID group.

RAID Backup Units
This server supports installation of one supercap Power Module (SCPM). The unit mounts to a bracket in-line with the fan modules (see Figure 3-22).
The optional SCPM provides approximately three years of backup for the disk write-back cache DRAM in the case of a sudden power loss by offloading the cache to the NAND flash.
For SCPM replacement instructions, see Replacing the Supercap Power Module (RAID Backup), page 3-41.

This section contains the following topics: · Obtaining the Driver Image File, page C-19 · Preparing Physical Installation Disks For Linux, page C-19 · Installing the Red Hat Linux Driver, page C-21 · Installing the SUSE Linux Enterprise Server Driver, page C-22
Obtaining the Driver Image File See Downloading the LSI MegaSR Drivers, page C-16 for instructions on obtaining the drivers. The Linux driver is offered in the form of dud-[driver version].img, which is the boot image for the embedded MegaRAID stack.
Note The LSI MegaSR drivers that Cisco provides for Red Hat Linux and SUSE Linux are for the original GA versions of those distributions. The drivers do not support updates to those OS kernels.
Preparing Physical Installation Disks For Linux This section describes how to prepare physical Linux installation disks from the driver image files, using either the Windows operating system or the Linux operating system.
Note The driver image is too large for a floppy disk, so use a USB thumb drive instead.

Note Alternatively, you can mount the dud.img file as a virtual floppy disk, as described in the installation procedures.
Preparing Physical Installation Disks with the Windows Operating System Under Windows, you can use the RaWrite floppy image-writer utility to create disk images from image files.

Step 1 Step 2
Step 3

Download the Cisco UCS C-Series drivers ISO, as described in Downloading the LSI MegaSR Drivers, page C-16 and save it to your Windows system that has a diskette drive. Extract the dud.img file: a. Burn the ISO image to a disc. b. Browse the contents of the drivers folders to the location of the embedded MegaRAID drivers:
/<OS>/Storage/Intel/C600/ c. Expand the Zip file, which contains the folder with the driver files. Copy the driver update disk image dud-[driver version].img and your file raw write.exe to a directory.

If necessary, use this command to change the filename of the driver update disk to a name with fewer than eight characters: copy dud-[driver version].img dud.img Open the DOS Command Prompt and navigate to the directory where raw write.exe is located. Enter the following command to create the installation diskette: raw write Press Enter. You are prompted to enter the name of the boot image file. Enter: dud.img Press Enter. You are prompted for the target disk. Insert a floppy disk into the server and enter: A: Press Enter. Press Enter again to start copying the file to the diskette. After the command prompt returns and the floppy disk drive LED goes out, remove the disk. Label the diskette with the image name.

Preparing Installation Disks with a Linux Operating System
Under Red Hat Linux and SUSE Linux, you can use a driver disk utility to create disk images from image files.

Note The driver image is too large for a floppy disk, so use a USB thumb drive instead.

Restoring RAID Configuration After Replacing a RAID Controller
When you replace a RAID controller, the RAID configuration that is stored in the controller is lost.

Step 1 Step 2
Step 3

Replace your RAID controller. See Replacing a PCIe Card, page 3-46.
If this was a full chassis swap, replace all drives into the drive bays, in the same order that they were installed in the old chassis.
Reboot the server and watch for the prompt to press F.

Note For newer RAID controllers, you are not prompted to press F. Instead, the RAID configuration is imported automatically. In this case, skip to Step 6.

Step 4 Step 5 Step 6

Press F when you see the following on-screen prompt:
Foreign configuration(s) found on adapter. Press any key to continue or `C' load the configuration utility, or `F' to import foreign configuration(s) and continue.
Press any key (other than C) to continue when you see the following on-screen prompt:
All of the disks from your previous configuration are gone. If this is an unexpected message, then please power of your system and check your cables to ensure all disks are present. Press any key to continue, or `C' to load the configuration utility.
Watch the subsequent screens for confirmation that your RAID configuration was imported correctly. · If you see the following message, your configuration was successfully imported. The LSI virtual
drive is also listed among the storage devices.
N Virtual Drive(s) found on host adapter.
· If you see the following message, your configuration was not imported. This situation can happen if you do not press F quickly enough when prompted. In this case, reboot the server and try the import operation again when you are prompted to press F.
0 Virtual Drive(s) found on host adapter.
