Chapter 2 Installing the Server

Initial Server Setup

This section includes the following topics:

•Connecting and Powering on the Server (Standalone Mode), page 2-11

•NIC Modes and NIC Redundancy Settings, page 2-14

Connecting and Powering on the Server (Standalone Mode)

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 a Cisco UCS integration,

specific cabling and settings are required. See Installation for Cisco UCS Integration, page E-1.

Note The server is shipped with a default NIC mode called Shared LOM EXT, default NIC redundancy is

active-active, and DHCP is enabled. Shared LOM EXT mode enables the 1-Gb Ethernet ports and the

ports on any installed Cisco virtual interface card (VIC) to access the Cisco Integrated Management

Interface (Cisco IMC). If you want to use the 10/100 dedicated management ports to access the Cisco

IMC, you can connect to the server and change the NIC mode as described in Step 4 of the following

procedure. In that step, you can also change the NIC redundancy and set static IP settings.

Step 1 Attach a supplied power cord to each power supply in your server, and then attach the power cord to a

grounded AC power outlet. See the Power Specifications, page A-2 for power specifications.

Wait for approximately two minutes to let the server boot in standby power during the first bootup.

You can verify the power status by looking at the Power Status LED (see Figure 1-1 on page 1-1):

•Off—No AC power is present in the server.

•Amber—The server is in standby power mode. Power is supplied only to the Cisco IMC and some

motherboard functions.

•Green—The server is in main power mode. Power is supplied to all server components.

Note During bootup, the server beeps once for each USB device that is attached to the server. Even if

no external USB devices are attached, there is a short beep for each virtual USB device such as

a virtual floppy drive, CD/DVD drive, keyboard, or mouse. A beep is also emitted if a USB

device is hot-plugged or hot-unplugged during a BIOS power-on self test (POST), or while you

are accessing the BIOS Setup utility or the EFI shell.

Step 2 Connect a USB keyboard and VGA monitor by connecting the supplied KVM cable to the KVM

connector on the front panel (see Figure 1-1 on page 1-1).

Note Alternatively, you can use the VGA and USB ports on the rear panel. However, you cannot use

the front panel VGA and the rear panel VGA at the same time. If you are connected to one VGA

connector and you then connect a video device to the other connector, the first VGA connector

is disabled.

Step 3 Connect Ethernet cables to the server ports or card ports that you want to use.

Initial Server Setup

Step 4 Set NIC mode and NIC redundancy, and choose whether to enable DHCP or set static network settings:

a. Press the Power button to boot the server. Watch for the prompt to press F8.

b. During bootup, press F8 when prompted to open the BIOS Cisco IMC Configuration Utility.

c. Set the NIC mode to your choice for which ports to use to access the Cisco IMC for server

management (see Figure 1-2 on page 1-2 for identification of the ports):

•Shared LOM EXT (default)—This is shared LOM extended mode, which is the factory default. This

default includes Active-active NIC redundancy with DHCP enabled. 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 the Cisco IMC through

a Cisco card in standalone mode.

•Dedicated—The 1-Gb dedicated management port is used to access the Cisco IMC. You must select

a NIC redundancy and IP setting.

•Shared LOM—The 1-Gb Ethernet ports are used to access the Cisco IMC. You must select a NIC

redundancy and IP setting.

•Shared LOM 10G—The 10 Gb Ethernet ports are used to access the 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.

Note Cisco Card NIC mode is currently supported only with a Cisco UCS VIC that is installed in PCIe

slot 5 or 10. See also Special Considerations for Cisco UCS Virtual Interface Cards, page 3-48.

d. 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.

–

Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.

–

Active-active—All Ethernet ports are used simultaneously. See NIC Modes and NIC

Redundancy Settings, page 2-14 for more information.

e. Choose whether to enable DHCP for dynamic network settings or to enter static network settings.

Note Before you enable DHCP, your DHCP server must be preconfigured 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 that are assigned to the Cisco IMC. The MAC address

printed on the label is the beginning of the range of six contiguous MAC addresses.

f. (Optional) Use this utility to make VLAN settings and to set a default Cisco IMC user password.

Note Changes to the settings take effect after approximately 45 seconds. Press F5 to refresh the

window and wait until the new settings appear before you reboot the server in the next step.

g. Press F10 to save your settings and reboot the server.

Initial Server Setup

Note If you chose to enable DHCP, the dynamically assigned IP and MAC addresses are displayed on

the console window during bootup.

Step 5 Use a browser and the IP address of the Cisco IMC to connect to the Cisco IMC Setup Utility. The IP

address is based upon the settings that you made in Step 4 (either a static address or the address assigned

by your DHCP server).

Note The default username for the server is admin. The default password is password.

Chapter 3 Maintaining the Server

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 or Replacing the Front Bezel (Optional), page 3-9

•Removing or Replacing the Server Top Cover, 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

hard drives can run.

•Standby power mode—Power is supplied only to the service processor and the cooling fans. It is

safe to power off the server from this mode.

You can invoke a graceful shutdown or a hard shutdown by using either the Cisco Integrated

Management Controller (Cisco IMC) interface or the Power button on the front panel.

Step 1 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.

Step 2 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.

•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.

Step 3 Disconnect the power cords from the power supplies in your server to completely remove AC power and

power off the server.

When using the Cisco UCS 12G SAS Modular

8-Port RAID Controller (UCSC-MRAID12G),

the 8 SAS/SATA drives must be in these 8 drive

bays.

2 Drive bays 1–12

All bays support SAS and SATA drives.

When using the Cisco UCS 12G SAS

Modular 12-Port RAID Controller

(UCSC-MRAIDC460), you can control all

12 SAS/SATA drives.

Cisco UCS C460 M4 Server Installation and Service Guide

OL-31215-01

Chapter 3 Maintaining the Server

Replacing Server Components

Observe these drive population guidelines for optimum performance:

•When using the Cisco UCS 12G SAS Modular 12-Port RAID Controller (UCSC-MRAIDC460), you

can control all 12 SAS/SATA drives. You can populate all 12 drive bays with SAS/SATA drives.

•When using the Cisco UCS 12G SAS Modular 8-Port RAID Controller (UCSC-MRAID12G), the

eight SAS/SATA drives must be in bays 3, 4, 6, 7, 8, 10, 11, and 12, as shown in Figure 3-6.

See RAID Controller Cabling, page C-4 for information about cabling for specific bays and how

those bays are grouped.

•Keep an empty drive blanking tray in any unused slots to ensure proper airflow.

•You can mix hard drives and SSDs in the same server. However, you cannot configure a logical

volume (virtual drive) that contains a mix of hard drives and SSDs. When you create a logical

volume, it must contain all hard drives or all SSDs.

Replacing a SAS or SATA Drive

Tip You do not have to shut down the server or drive to replace SAS/SATA hard drives or SSDs because they

are hot-swappable. To replace an NVMe PCIe SSD drive, which must be shut down before removal, see

Replacing an NVMe PCIe SSD, page 3-17

For information about drive tray LEDs, see Front-Panel LEDs, page 3-2.

Step 1 Remove the drive that you are replacing or remove a blank tray from an empty bay:

a. Remove the front bezel from the server, if one is attached. See Removing or Replacing the Front

Bezel (Optional), page 3-9.

b. Press the release button on the face of the drive tray. See Figure 3-7.

c. Grasp and open the ejector lever and then pull the drive tray out of the slot.

d. If you are replacing an existing drive, remove the four drive tray screws that secure the drive to the

tray and then lift the drive out of the tray.

Step 2 Install a new drive:

a. Place a new drive in the empty drive tray and replace the four drive tray screws.

•NVMe PCIe SSD Requirements and Restrictions, page 3-17

•Replacing an NVMe PCIe SSD, page 3-17

NVMe PCIe SSD Population Guidelines

Populate NVMe PCIe SSDs only in bays 5 and 9 (see Figure 3-6).

Note Installing two NVMe PCIe SSDs requires four CPUs in the system. You can use only drive bay 5 for

these drives in a two-CPU system (see the table below).

NVMe PCIe SSD Requirements and Restrictions

Observe these restrictions for NVMe PCIe SSDs:

•You cannot boot from an NVMe PCIe SSD.

•You cannot control an NVMe PCIe SSD 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 or

SATA Drive, page 3-15.

Replacing an NVMe PCIe SSD

For information about drive tray LEDs, see Front-Panel LEDs, page 3-2.

Step 1 Shut down the NVMe PCIe SSD. Use your operating system interface to shut down the drive, and then

observe the drive-tray status 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.

Step 2 Remove the drive that you are replacing:

a. Remove the front bezel from the server, if one is attached. See Removing or Replacing the Front

Bezel (Optional), page 3-9.

Replacing Memory Risers

Caution DDR4 memory risers are available for use with DDR4 DIMMs and EX v3 CPUs. You must upgrade to

Cisco IMC 2.0(6) or later firmware before you upgrade the hardware. See Special Information For

Upgrades to Intel Xeon v3 Series CPUs, page 3-29.

The 8 memory risers connect to motherboard sockets and each riser provides 12 DIMM slots. Each riser

has two memory buffers, each with two DDR channels of three DIMMs. The memory riser is

hot-pluggable when you use the Attention button to take the riser offline, as described in the procedure

in this section. (This feature is available only on supported operating systems. Some operating systems

support only hot-add, but not hot-remove.)

Note See the release notes for your operating system and your Cisco IMC/BIOS release for details and

restrictions on hot-plugging: Cisco IMC Release Notes.

Figure 3-9 Memory Riser LEDs (Top View)

Memory Riser Population Guidelines

Use the following guidelines when populating memory risers:

•Each CPU supports two memory risers.

•The minimum memory riser configuration is one riser installed on CPU1 or CPU2, with at least one

DIMM. The minimum DIMM capacity must meet the requirements of the OS installed.

•If not installing all memory risers, populate the even-numbered riser slots first to ensure optimum

CPU airflow.

Replacing a Memory Riser

The qualified and supported part numbers for this component are subject to change over time. For the most

up-to-date list of replaceable components, see the following URL and then scroll to Technical Specifications:

http://www.cisco.com/en/US/products/ps10493/products_data_sheets_list.html

Step 1 Remove the memory riser that you are replacing (see Figure 3-10):

a. Slide the server out the front of the rack far enough so that you can remove the top cover.

b. Remove the top cover as described in Removing or Replacing the Server Top Cover, page 3-10.

Caution Memory risers are hot-pluggable, which means that you do not have to remove power from the server,

but you must shut down the riser before removing it as described in the following steps.

c. Press the attention button on the top of the memory riser to shut down the riser in the BIOS (see

Figure 3-9).

d. Wait until the attention LED (ATTN) and the power LED (PWR) turn off.

e. Press both green riser-latch release buttons on the top of the riser (see Figure 3-10).

f. Lift on both riser latches at the same time. The lever action disengages the riser’s connector from

the motherboard socket.

g. Grasp the open retaining latches and lift the memory riser straight up and out of the server.

h. To remove DIMMs from the memory riser, use the instructions in Replacing DIMMs, page 3-23.

Step 2 Install a new memory riser:

Note When you install more than one memory riser, you must install and activate one riser at a time before

you install and activate the next riser. That is, do not attempt to install all risers and then activate them.

a. To install DIMMs to the new memory riser, use the instructions in Replacing DIMMs, page 3-23.

b. Ensure that the riser retaining latches are in the open position.

c. Align the riser with the empty motherboard socket and the card guides at each end of the riser (on

the chassis mid-brace and the rear of the fan cage).

d. Lower the riser until it makes contact with the motherboard socket.

e. Close each retaining latch at the same time to fully engage the riser with the motherboard socket.

f. Press the attention button on the top of the memory riser (see Figure 3-9), and then wait until the

attention LED (ATTN) turns off and the power LED (PWR) turns on.

g. If you have more memory risers to install, follow steps a. through f. for each riser.

Caution DIMMs and their sockets are fragile and must be handled with care to avoid damage during installation.

Caution Cisco does not support thir sco DIMMs in the server might result in system d-party DIMMs. Using non-Ci

problems or damage to the motherboard.

Note To ensure the best server performance, it is important that you are familiar with memory performance

guidelines and population rules before you install or replace the memory.

DIMM Performance Guidelines and Population Rules

This section describes the type of memory that the server requires and its effect on performance. The section

includes the following topics:

•DIMM Sockets, page 3-23

•DIMM Population Rules, page 3-24

•Memory Mirroring Mode, page 3-27

•Lockstep Channel Mode, page 3-27

DIMM Sockets

Figure 3-11 shows the DIMM sockets and how they are numbered on a memory riser.

•Each memory riser has 12 DDR3 DIMM sockets.

•Channels are labeled with letters as shown in Figure 3-11. For example, channel A = DIMM slots A1, A2,

A3.

•Each channel has three DIMM sockets. The blue socket in a channel is always socket 1.

DIMM Population Rules

Observe the following guidelines when installing or replacing DIMMs:

•The minimum configuration without memory mirroring is one memory riser installed on a slot for

CPU1 or CPU2, with one DIMM. The minimum DIMM capacity must meet the requirements of the

OS installed.

•The minimum configuration with memory mirroring is one memory riser installed on a slot for

CPU1 or CPU2, with two matched DIMM pairs. A matched DIMM pair is two DIMMs with the

same Cisco part number (same capacity, same rank, and same buffer type (RDIMM or LRDIMM)).

•For optimal performance, spread DIMMs evenly across all CPUs and DDR channels.

•Any DIMM installed in a memory riser that corresponds to an empty CPU slot is inaccessible. In a

two-CPU server, memory risers 5–8 are not available.

•Populate the DIMM 1 slots on a riser first, then the DIMM 2 slots, then the DIMM 3 slots. For

example, populate the DIMM slots on a riser in this order:

1. A1, C1, B1, D1

2. A2, C2, B2, D2

3. A3, C3, B3, D3

•See the following tables for the recommended population order for optimum performance.

–

Table 3-4: Two-CPU/four-riser system

–

Table 3-5: Four-CPU/eight-riser system

•Do not mix RDIMMs and LRDIMMs.

•NVIDIA GPUs can support only less than 1 TB of memory in the server. Therefore, do not install

1 TB or more total memory when using an NVIDIA GPU card in this server.

Chapter 3 Maintaining the Server

Memory Mirroring Mode

When you enable memory mirroring mode in the server BIOS, the memory subsystem simultaneously

writes identical data to two channels. If a memory read from one of the channels returns incorrect data

due to an uncorrectable memory error, the system automatically retrieves the data from the other

channel. A transient or soft error in one channel does not affect the mirrored data, and operation

continues.

Memory mirroring reduces the amount of memory available to the operating system by 50 percent

because only one of the two populated channels provides data.

Lockstep Channel Mode

In this mode, the main memory channel from the CPU to the memory buffer runs at the same clock rate

of each of the two memory subchannels from the buffer to the DIMMs, and both DIMM subchannels are

accessed simultaneously for a double-width access. For example, if the CPU channel clock speed is 1600

MHz, each of the DIMM subchannels operates at 1600 MHz. For this reason, lockstep mode is referred

to as 1:1. Memory lockstep mode provides protection against both single-bit and multi-bit errors.

Memory lockstep allows two memory channels to work as a single channel, moving a data word two

channels wide and providing eight bits of memory correction.

Lockstep channel mode requires that all four memory channels on a CPU must be populated identically

with regards to size and organization. DIMM socket populations within a channel 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.

Replacing a DIMM

This section includes the following topics:

•Identifying a Faulty Memory Riser or DIMM, page 3-28

•Replacing DIMMs, page 3-28

Identifying a Faulty Memory Riser or DIMM

The memory riser includes fault LEDs on its top panel (see Figure 3-9).

•If the riser fault LED is lit, replace the memory riser as described Replacing a Memory Riser,

page 3-21.

•If one or more of the numbered DIMM fault LEDs are lit, replace the corresponding DIMMs as

described in Replacing DIMMs, page 3-23.

Replacing DIMMs

Step 1 Remove the DIMMs that you are replacing:

a. Slide the server out the front of the rack far enough so that you can remove the top cover.

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

b. Remove the top cover as described in Removing or Replacing the Server Top Cover, page 3-10.

Caution Memory risers are hot-pluggable, which means that you do not have to remove power from the server,

but you must shut down the riser before removing it.

c. Locate the memory riser that has the faulty DIMM, and then shut down and remove the riser as

described in Replacing Memory Risers, page 3-20.

d. Locate the faulty DIMM and remove it from the socket on the riser by opening the ejector levers at

both ends of the DIMM socket.

Step 2 Install a new DIMM:

Note Before installing DIMMs, refer to the population guidelines. See DIMM Performance

Guidelines and Population Rules, page 3-23.

a. Align the new DIMM with the socket on the riser. Use the alignment key in the DIMM socket to

correctly orient the DIMM.

b. Push the DIMM into the socket until it is fully seated and the ejector levers on either side of the

socket lock into place.

c. Replace the memory riser to its motherboard socket and bring it back online by using the procedure

in Replacing Memory Risers, page 3-20.

d. Replace the top cover.

Special Information For Upgrades to Intel Xeon v3 Series CPUs

Caution You must upgrade your server firmware to the required minimum level before you upgrade to v3 Series

CPUs. Older firmware versions cannot recognize the new CPUs and this results in a non-bootable server.

Caution Intel Xeon v3 Series CPUs require DDR4 memory risers and DDR4 DIMMs to operate.

The minimum software and firmware versions required for the server to support Intel E7-4800 or

E7-8800 v3 Series CPUs are as follows:

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 3-6, you can install 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 v3 Series CPUs

to upgrade your firmware. After you upgrade, return to the procedure in this section to install the

CPU and heatsink hardware.

Replacing Server Components

CPU Configuration Rules

The server supports two or four CPUs. See Figure 3-11 on page 3-24 for the CPU socket numbering.

•The minimum configuration is two identical CPUs (CPU1 and CPU2).

•The server must have either two or four identical CPUs to operate; populate CPU1 and CPU2 first,

then populate CPU3 and CPU4.

•In a two-CPU server (CPU1 and CPU2), the following components are not available because they

require CPU3 and CPU4 to be installed:

–

PCIe riser 2 (PCIe slots 6–10)

–

Memory risers 5–8

Caution In a two-CPU system, you must have the CPU filler panel installed in place of CPU3 and CPU4 to

maintain correct airflow and cooling.

Replacing a CPU and Heat Sink

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 heat sinks and their thermal pads to ensure proper

cooling. Failure to install a CPU correctly might result in damage to the server.

Caution The Intel Pick-n-Place tools used in this procedure are required to prevent damage to the contact pins

between the motherboard and the CPU. Do not attempt this procedure without the required tools, which

are included with each CPU option kit. If you do not have the tool, you can order a spare (Cisco PID

UCS-CPU-EP-PNP=).

Step 1 Prepare the server for replacement:

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.

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

c. Remove the top cover as described in Removing or Replacing the Server Top Cover, page 3-10.

Cisco UCS C460 M4 Server Installation and Service Guide

OL-31215-01

Chapter 3 Maintaining the Server

Replacing Server Components

Step 2 Provide clearance for removing the CPU:

a. Remove all memory risers from the server.

With power removed from the server, you do not have to shut down the memory risers before

removal. Press both green riser-latch release buttons on the top of the riser (see Figure 3-10), and

then lift on both riser latches at the same time.

Note It is important that each memory riser is returned to the same slot it was removed from to

maintain your DIMM configuration. Label the risers or organize them in order as you remove

them and set them aside on an antistatic surface.

b. Remove both PCIe risers from the server.

Lift on the retaining latch at the top of the riser until it is vertical (see Figure 3-19).

c. Remove the chassis mid-brace (see Figure 3-5 on page 3-11).

Note The securing mechanism for the mid-brace differs, depending on when the system was produced.

–

Older systems have a spring-loaded plunger that secures each end of the mid-brace. Access

these plungers on the inside of the chassis. Pull inward on the spring-loaded plunger that secures

each end of the mid-brace, then lift straight up.

–

Newer systems have two screws that secure each end of the mid-brace. Access these screws on

the outside of the chassis. Remove the two screws at each end of the mid-brace, then lift straight

up.

Step 3 Use a Number 2 Phillips-head screwdriver to loosen the four captive screws that secure the heat sink,

and then lift it off of the CPU.

Enabling the Intel TXT Feature in the BIOS

Intel Trusted Execution Technology (TXT) provides greater protection for information that is used and

stored on the business server. A key aspect of that protection is the provision of an isolated execution

environment and associated sections of memory where operations can be conducted on sensitive data,

invisibly to the rest of the system. Intel TXT provides for a sealed portion of storage where sensitive data

such as encryption keys can be kept, helping to shield them from being compromised during an attack

by malicious code.

Step 1 Reboot the server and watch for the prompt to press F2.

Step 2 When prompted, press F2 to enter the BIOS Setup utility.

Step 3 Verify that the prerequisite BIOS values are enabled:

a. Choose the Advanced tab.

b. Choose Intel TXT(LT-SX) Configuration to open the Intel TXT(LT-SX) Hardware Support

Replacing Server Components

Replacing Power Supplies

The server requires four 1400 W power supplies. When four power supplies are installed they are

redundant as 2+2.

Note If you have ordered a server with power supply redundancy (four power supplies), you do not have to

power off the server to replace power supplies because they are redundant as 2+2.

Step 1 Remove the power supply that you are replacing or a blank panel from an empty bay (see Figure 3-28):

a. Perform one of the following actions:

–

If your server has only two power supplies, shut down and power off the server as described in

Shutting Down and Powering Off the Server, page 3-8.

–

If your server has four power supplies, you do not have to power off 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.

Step 2 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 powered off the server, press the Power button to return the server to main power mode.

RAID Card Firmware Compatibility

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.

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

Supercap Power Module (RAID Backup Unit)

This server supports installation of one supercap power module (SCPM) backup unit. The unit mounts

to a bracket on the chassis wall adjacent to the internal RAID controller slot (see Replacing the Supercap

Power Module (RAID Backup Unit), page 3-41).

The SCPM provides approximately 3 years of backup for the disk write-back cache DRAM in the case

of sudden power loss by offloading the cache to the NAND flash.

RAID Controller Cabling

Cabling an 8-Port RAID Controller

An 8-port RAID controller can control 8 drives.

Note When using an 8-port RAID controller, you must populate the eight drives that you want to control in

drive bays (3, 6, 7, 10) and (4, 8, 11, 12). That is, you must populate the bays that are controlled by SAS

Appendix C RAID Controller Considerations

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 Replace your RAID controller. See Special Considerations for Cisco UCS Virtual Interface Cards,

page 3-48.

Step 2 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.

Step 3 Reboot the server and watch for the prompt to press F.

Step 4 Press F when you see the following onscreen 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.

Step 5 Press any key (other than C) to continue when you see the following onscreen 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.

Step 6 Watch the subsequent windows 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 problem can occur 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.

For More Information

The LSI utilities have help documentation for more information about using the utilities.

For basic information about RAID and for using the utilities for the RAID controller cards, see the

Cisco UCS Servers RAID Guide.

NVIDIA GPU Slot Population Rules

•The GPU cards are double-wide and cover two slots. A GPU cards in slot 2 also covers slot 1. A GPU

card in slot 7 also covers slot 6.

•NVIDIA GPUs can support only less-than 1 TB of memory in the server. Therefore, do not install

1 TB or more total memory when using an NVIDIA GPU card in this server.

•Table D-2 shows the rules for populating NVIDIA GPU cards in the server.

Requirement For All Supported GPUs: Memory-Mapped I/O Greater than 4 GB

All supported GPU cards require enablement of the BIOS setting that allows greater than 4 GB of

memory-mapped I/O (MMIO).

Standalone Server

If the server is used in standalone mode, this BIOS setting is enabled by default:

Advanced > PCI Configuration > Memory Mapped I/O Above 4 GB [Enabled]

If you need to change this from a different setting, enter the BIOS Setup Utility by pressing F2 when

prompted during bootup.

Cisco UCS Manager Controlled Server

If the server is integrated with Cisco UCS Manager and controlled by a service profile, this setting is not

enabled by default in the service profile. You must enable it with a BIOS policy in your service profile.

Step 1 Refer to the Cisco UCS Manager configuration guide (GUI or CLI) for your release for instructions on

configuring service profiles:

Cisco UCS Manager Configuration Guides

Step 2 Refer to the chapter on Configuring Server-Related Policies > Configuring BIOS Settings.

Step 3 In the section of your profile for PCI Configuration BIOS Settings, set Memory Mapped IO Above 4GB

Config to one of the following:

•Enabled—Maps I/O of 64-bit PCI devices to 64 GB or greater address space.

•Platform Default—The policy uses the value for this attribute contained in the BIOS defaults for the

server. Use this only if you know that the server BIOS is set to use the Enabled default setting.

Step 4 Reboot the server.

Note Cisco UCS Manager pushes BIOS configuration changes through a BIOS policy or default BIOS

settings to the Cisco Integrated Management Controller (Cisco IMC) buffer. These changes

remain in the buffer and do not take effect until the server is rebooted.

Appendix D GPU Card Installation

Installing a GPU Card

Note For NVIDIA K80 and M60 GPU: When installed in the Cisco UCS C460 M4 server, the K80 and M60

GPUs use a different cable than the other GPU cards. You must order this cable when you order the K80

or M60 GPU (Cisco PID UCSC-300W-460M4).

Step 1 Remove a GPU card (or a blank filler panel) from the PCIe riser assembly:

a. Shut down and 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.

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

c. Remove the top cover as described in Removing or Replacing the Server Top Cover, page 3-10.

d. Lift the blue plastic retaining latch at the top of the PCIe riser until the latch is vertical (see

Figure 3-19). The lever action disengages the riser’s connector from the motherboard socket.

e. Lift straight up on both ends of the PCIe riser and remove it from the server. Set the riser on an

antistatic surface.

f. Open the hinged blue plastic card cover (see Figure 3-21).

g. Open the hinged card-tab retainer (see Figure 3-21). Pinch the two blue finger-grips toward the center

and swing open the retainer.

h. Pull evenly on both corners of the GPU card to remove it from the socket on the PCIe riser.

i. Disconnect the GPU card’s power cable from the PCIe riser power connector.

Step 2 Install a GPU card:

a. Connect the white connector of the included power cable to the white power-connector on the riser.

The power connector is adjacent to PCIE 2 on riser 1 or PCIE 6 on riser 2 (see Figure 3-21).

Caution Do not reverse the GPU power cable. Connect the black connector on the cable to the black connector on

the GPU card. Connect the white white connector on the cable to the connector on the PCIe riser. Never

connect a 6-pin cable connector to an 8-slot receptacle.

Note Your GPU card might be shipped with two power cables: a straight cable and a Y-cable. The straight cable

is used for connecting power to the GPU card in this server; do not use the Y-cable, which is used for

connecting the GPU card in external devices only.

Caution For NVIDIA K80 or M60: When installed in a Cisco UCS C460 M4 server, the NVIDIA K80 or M60

GPU must use a different power cable than other GPUs (UCSC-300W-460M4). You must plug the black

8-pin connector into the black connector on the GPU card and plug the white 10-pin connector into the

white power connector on the PCIe riser.
