Initial Server Setup

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 UCS integration, specific
cabling and settings are required. See Installation for Cisco UCS Manager 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 an y 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. You can change this to IPv6.

Chapter 2 Installing the Se rver

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 requires a KVM cable (Cisco PID N20-BKVM). 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 through Figure 1-4). 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 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-2 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 pa nel (se e

External Features Overview, page 1-1). The system is in standby power mode when the LED is amber.

Step 2 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).

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 pa nel (se e

External Features Overview, page 1-1). The system is in standby power mode when the LED is amber.

Step 2 Plug your management Ethernet cable into the dedicated management port on the rear panel (see

External Features Overview, page 1-1).

Initial Server Setup

Step 3 Allow your preconfigured DHCP server to assign an IP address to the server node.
Step 4 Use the assigned IP address to access and log in to the Cisco IMC for the server node. Consult with your

DHCP server administrator to determine the IP address.

Note The default user name for the server is admin. The default password is password.

Step 5 From the Cisco IMC Server Summary page, click Launch KVM Console. A separate KVM console

window opens.

Initial Server Setup

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 Set NIC mode and NIC redundancy:

a. Set the NIC mode to choose wh ich ports to u se to access Cisco IMC for server management (see

Figure 1-5 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.

• 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.

Chapter 2 Installing the Se rver

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 2 is the primary slot, but you can use slot 1.

–

If you select Riser2, slot 5 is the primary slot, but you can use slot 4.

–

If you select Flex-LOM, you must use an mLOM -style VIC in th e mLOM s lot.

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 o ver if there is a problem. Th is
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.

Step 2 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 printe d on a labe l on the rear of the se rver. 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.

2-12

The static IPv4 and IPv6 settings include the following:

• The Cisco IMC IP address.

• The prefix/subnet.

For IPv6, valid values are 1–127.

NIC Modes and NIC Redundancy Settings

NIC Modes and NIC Redundancy Settings

NIC Modes

This server has the following NIC mode settings that you can choose from:

• Shared LOM EXT (default)—This mode is the shared LOM extended mode that is the

factory-default setting. W ith 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 syst em , 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.

Chapter 2 Installing the Se rver

• VIC Slot—If you use the Cisco Card NIC mode, you select this setti ng to match where your VIC is

NIC Redundancy

This server has the following NIC redundancy settings that you can choose from:

installed. The choices are Riser1, Riser2, or Flex-LOM (the mLOM slot).

–

If you select Riser1, slot 2 is the primary slot, but you can also use slot 1.

–

If you select Riser2, slot 5 is the primary slot, but you can also use slot 4.

–

If you select Flex-LOM, you must use an mLOM -style VIC in th e mLOM s lot.

–

None—The Ethernet ports operate independently and do not fail o ver if there is a problem. Th is
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/activ e 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 recei v ed by the current sla v e. If the recei ving sla v e f ails, another sla v e takes
over the MAC address of the failed receiving slave.

This section describes how to prepare for component installation, and it includes the following topics:

• Required Equipment, page 3-9

• Shutting Down and Powering Off the Server, page 3-9

• Removing and Replacing the Server Top Cover, page 3-10

• Serial Number Location, page 3-12

• Hot-Swap or Hot-Plug Replacement, page 3-12

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

Preparing for Server Component Installation

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 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.

OL-32474-01

• 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 power off the server.

Preparing for Server Component Installation

Removing and Replacing the Server Top Cover

Step 1 Remove t h e to p c over ( s ee Figure 3-4).

a. If the cover latch is locked, use a screwdriver to turn the lock 90-degrees counterclockwise to unlo ck

it. See Figure 3-4.

b. Lift on the end of the latch that has the green finger grip. The cover is pushed back to the open

position as you lift the latch.

c. Lift the top cover straight up from the server and set it aside.

Step 2 Replace the top cover:

Note The latch must be in the fully open position when you set the cover back in place, which allows

the opening in the latch to sit over a peg that is on the fan tray.

a. With the latch in the fully open position, place the cover on top of the server about one-half inch

(1.27 cm) behind the lip of the front cover panel. The opening in the latch should fit over the peg
that sticks up from the fan tray.

b. Press the cover latch down to the closed posi tion. The co ver is pushed forwar d to the closed posit ion

as you push down the latch.

c. If desired, lock the latch by using a screwdriver to turn the lock 90-degrees clockwise.

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.

• You can mix hard drives and solid state drives in the same server. 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 hard drives or all SSDs.

Drive Replacement Procedure

Tip You do not have to shut down or power off the server to replace SAS/SATA hard drives or solid state

drives (SSDs) because they are hot-swappable.

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

a. Press the release button on the face of the drive tray. See Figure 3-10.
b. Grasp and open the ejector lever and then pull the drive tray out of the slot.
c. 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.
b. With the ejector lever on the drive tray open, insert the drive tray into the empty drive bay.
c. Push the tray into the slot until it touches the backplane, and then close the ejector lever to lock the

drive in place.

This section includes the following topics:

• Memory Performance Guidelines and Population Rules, page 3-20

• DIMM Replacement Procedure, page 3-23

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

Caution Cisco does not support third-party DIMMs. Using non-Cisco DIMMs in the server might result in system

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.

Chapter 3 Maintaining the Server

Front of Server

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).

B2

B1

A3

A2

A1

352815

• 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, you mu st install DIMMs
in sets of 4, 6, 8, or 12 as described in Memory Mirroring and RAS, page 3-22.

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

more than fourteen 64-GB DIMMs when using an NVIDIA GPU card in this server.

• Observe the DIMM mixing rules shown in Table 3-5.

OL-32474-01

Table 3-5 DIMM Mixing Rules for C240 M4 Servers

DIMM Parameter DIMMs in the Same Channel DIMMs in the Same Bank

DIMM Capacity:
RDIMM = 8 or 16 GB
LRDIMM = 32 or 64 GB

DIMM Speed:
2133 or 2400 MHz

DIMM Type:
RDIMMs or LRDIMMs

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 conf igurations, see the specif ication sheet for
the server:

• Cisco UCS C240 M4 High Density Rack Server (Small Form-Factor Disk Drive Model)

• Cisco UCS C240 M4 High Density Rack Server (Large Fo rm-Factor Disk Drive Model)

• You can mix different capacity

DIMMs in the same channel (for
example, A1, A2, A3).

Y ou can mix speeds, but DIMMs will run at
the speed of the slowest DIMMs/CPUs
installed in the channel.

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

Specification Sheet

Specification Sheet

• 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.

You can mix speeds, but DIMMs will run at
the speed of the slowest DIMMs/CPUs
installed in the bank.

Lockstep Channel Mode

Cisco UCS C240 M4 Server Installation and Service Guide

3-22

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 f our memory channels on a CPU must be populated identically
with regard to size and organization. DIMM sock et popu lations within a channel (for example, A1, A2,
A3) do not have to be identical but the same DIMM slot loca tion 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 3-23

• Replacing DIMMs, page 3-23

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.

Replacing DIMMs

Step 1 Power off the server as described in Shutting Down and Powering Off the Server, page 3-9.
Step 2 Slide the server out the front of the rack far enou gh so that you can remov e the top co ver. Y ou might ha ve

Step 3 Remove t h e to p c over a s d e s c ri b ed i n Removing and Replacing the Server Top Cover, page 3-10.
Step 4 Remove the air baffle that sits over the DIMM sockets and set it aside.
Step 5 Identify the faulty DIMM by observing the DIMM socket fault LEDs on the motherboard (see

Figure 3-3).

Step 6 Remove the DIMMs that you are replacing. Open the ejector levers at both ends of the DIMM socket,

and then lift the DIMM out of the socket.

Step 7 Install a new DIMM:

Note Before installing DIMMs, see the population guidelines. See Memory Performance Guidelines

and Population Rules, page 3-20.

a. Align the new DIMM with the empty socket on the motherboard. Use the alignment key in the

DIMM socket to correctly orient the DIMM.

b. 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.

Step 8 Replace the air baffle.
Step 9 Replace the top cover.

• 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, which contains PCIe slots 4, 5, and 6 is unavailable.

Chapter 3 Maintaining the Server

Replacing a CPU and Heatsink

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 grease 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 Power off the server as described in Shutting Down and Powering Off the Server, page 3-9.
Step 2 Slide the server out the front of the rack far enou gh so that you can remov e the top co ver. Y ou might ha ve

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.

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.

• 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-C240M4=)

–

Heat sink cleaning kit (UCSX-HSCK=)

A CPU heatsink cleaning kit is good for up to four CPU and heatsi nk cleanings. The cleaning kit con tains
two bottles of solution, one to clean the CPU an d heatsink of old ther mal interface materi al 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.

Replacing the Supercap Power Module (RAID Backup Battery)

This server supports installation of one supercap power module (SCPM). The unit mounts to a clip on
the removable air baffle (see Figure 3-19). The SCPM requires that you have a transportable memory
module (TMM) attached to your RAID controller card because the connector for the SCPM cable is on
the TMM.

See also:

• Replacing a Cisco Modular RAID Controller Card, page 3-30

• Replacing a Modular RAID Controller Transportable Memory Module (TMM), page 3-32

The 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.

Enabling Higher Power-Draw for Fusion ioDrive3 Cards

Some Fusion ioDrive3 accelerator cards such as the 5800 GB card draw 25 W by default b ut can achie v e
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 po wer dra w of 55 W (75 W maximum) when conf ig ured with the

override parameter in the IO Accelerator VSL software.

Note See the UCS power calculator to determine the total power draw for your exact server configuration at

http://www.cisco.com/assets/cdc_content_elements/ flash/da taCent er/cisco_ ucs_power_calc ulator/

How to Enable Higher Power Draw for a Device with the IO Accelerator Override Parameter

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 paramete r is enabled by device, by using the device serial
numbers.

Note The override parameter persists in the server and enables full power draw on an enabled device even if

the device is removed and then placed in a different slot within the same system. If the device is moved
to a slot that is not rated to provide 55 W of power, the server hardware could experience a power drag.

3-48

Cisco UCS C240 M4 Server Installation and Service Guide

OL-32474-01

Chapter 3 Maintaining the Server

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 de vi ce by usin g the fio-status command in the IO

Accelerator VSL software. Sample output is shown here:

fio-status

Adapter: Dual Controller Adapter
Fusion-io ioDrive2 3.0TB, Product Number:F01-001-2T41-CS-0001, FIO SN:1149D0969
External Power: NOT connected
PCIe Power limit threshold: 24.75W
Connected ioMemory modules:
fct2: SN:1149D0969-1121
fct3: SN:1149D0969-1111

In this example, 1149D0969 is the adapter serial number. If you have multiple Fusion ioDrive3 devices
installed in your system, use the

Installing or Replacing Server Components

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 adapt er serial number (FIO SN in th e sample output
above).

Step 2 Set the override parameter by editing t he /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

Step 3 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 3-50

• Resolving Insufficient 16-Bit I/O Space, page 3-5 1

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 e xecute 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 suf ficient memory sp ace to load any PCIe option R OM, it skips load ing
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 INSTANCE DESCRIPTION
146 Major N/A PCI out of resources error.

Major severity requires user
intervention but does not
prevent system boot.

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 ev en with the option R OMs for those
slots are enabled, the RAID controller option ROM might not have sufficient memory space to
execute. In that case, disable other op tion 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.

Chapter 3 Maintaining the Server

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 contr oller is in tegrated 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 tak e excessi v e time to complete, which appears t o 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.

Installing or Replacing Server Components

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 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.

GPU Card Configuration Rules

The rules for configuring the server with GPUs differ , depending on the server version and other factors.
Observe the following rules when populating GPUs in the server:

• For riser 1, use version 1A (slot 2) for GPU cards. This server can be ordered with one of three PCIe

riser 1 versions. GPU cards are not supported in version 1B (UCSC-PCI-1B-240M4) or 1C
(UCSC-PCI-1C-240M4).

• GPU cards are also supported in PCIe riser 2, slot 5.

Caution Cisco C240 M4 LFF and C240 M4 SFF 24-drive servers only: When using NVIDIA GPU cards, you

must preserve at least 10 mm of space between servers to ensure adequate air flow. When using GPU
cards with this version of the server, the operating temperature range is 32° to 95° F (0° to 35° C).

• Mixing rules:

–

You can mix GRID K1 and K2 GPU cards in the same server.

–

Do not mix GRID GPU cards with Tesla GPU cards in the same server.

–

Do not mix different models of Tesla GPU cards in the same server.

• All GPU cards require two CPUs and two minimum 1400 W power supplies in the server.

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

more than fourteen 64-GB DIMMs when using an NVIDIA GPU card in this server.

Note When you install a GPU card in slot 2, NCSI support in riser 1A automatically moves to slot 1. When

Riser 1A, slot 2 Riser 1A, slot 2

and
Riser 2, slot 5

you install a GPU card in slot 5, NCSI support in riser 2 automatically moves to slot 4. Therefore, you
can install a GPU card and a Cisco UCS VIC in the same riser.

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 inte grat ed with Ci sco UCS Manag er and co ntrolled by a ser vice prof ile, 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 default enabled setting
for this item.

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 (CIMC) buffer. These changes remain
in the buffer and do not take effect until the server is rebooted.
