Preparing for Server Installation
Rack Requirements
This section provides the requirements for the standard open racks, assuming an external ambient air
temperature range of 41F to 95F (5C to 35C).
The rack must be of the following type:
•
A standard 19-in. (48.3-cm) wide, four-post EIA rack, with mounting posts that conform to English
universal hole spacing, per section 1 of ANSI/EIA-310-D-1992.
•
The rack post holes can be square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), #12-24 UNC, or
#10-32 UNC when you use the supplied slide rails.
•
The minimum vertical rack space per server must be two RUs, equal to 3.5 in. (88.9 mm).
Equipment Requirements
The slide rails supplied by Cisco Systems for this server do not require tools for installation if you install
them in a rack that has square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), or #12-24 UNC threaded
holes. The inner rails (mounting brackets) are preattached to the sides of the server.
However, if you install the slide rails in a rack that has #10-32 round holes, a flat-bladed screwdriver is
required to remove the larger square or round mounting pegs from the front of the slide rails.
Slide Rail Adjustment Range
The slide rails for this server have an adjustment range of 26 to 36 inches (660 to 914 mm).

This section describes how to install the server in a rack.
Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special
precautions to ensure that the system remains stable. The following guidelines are provided to ensure
your safety:
This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component
at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
Statement 1006
To install the slide rails and the server into a rack, follow these steps:
Step 1
Install the slide rails into the rack (see Figure 2-2):
a.
Align the slide-rail assembly inside the rack posts with the length-adjustment bracket (Figure 2-2,
item 4) toward the rear of the rack.
b.
Compress the length-adjustment bracket until the mounting pegs (item 5) and locking clips (item 6)
on the slide-rail assembly engage the desired rack holes on the front and rear rack posts:
– The mounting pegs fit square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), or #12-24 UNC
threaded holes. They fit the shape of the hole when the pegs are compressed.
– The smaller #10-32 round mounting pegs are enclosed in the center of the compressible rear
pegs. However, to use the #10-32 pegs, you must use a flat-bladed screwdriver to remove the
square or round front pegs.

Initial Server Setup
Initial Server Setup
This section includes the following topics:
•
Connecting and Powering On the Server (Standalone Mode), page 2-8
•
NIC Modes and NIC Redundancy Settings, page 2-11
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 D-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 (CIMC). If you want to use the 10/100 dedicated management ports to access the CIMC, 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.
To perform initial setup of the server, follow these steps:
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—There is no AC power present in the server.
•
Amber—The server is in standby power mode. Power is supplied only to the CIMC and some
motherboard functions.
•
Green—The server is in main power mode. Power is supplied to all server components.
Note
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
Step 3
During bootup, the server beeps once for each USB device that is attached to the server. Even if
there are no external USB devices 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.
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.
Connect Ethernet cables to the server ports or card ports that you want to use.

Chapter 2
Installing the Server
Initial Server Setup
Step 4
Note
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 CIMC Configuration Utility.
The first time that you enter the Cisco IMC Configuration Utility, you are prompted to change the default
password. The default password is password. The Strong Password feature is enabled.
The following are the requirements for Strong Password:
•
The password can have minimum 8 characters; maximum 14 characters.
•
The password must not contain the user’s name.
•
The password must contain characters from three of the following four categories:
– English uppercase letters (A through Z).
– English lowercase letters (a through z).
– Base 10 digits (0 through 9).
– Non-alphabetic characters !, @, #, $, %, ^, &, *, -, _, =, “
c.
Set the NIC mode to your choice for which ports to use to access the CIMC 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. This is the factory-default
setting, along with Active-active NIC redundancy and 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 CIMC through a Cisco
card in standalone mode.
•
Dedicated—The 10/100 management port is used to access the CIMC. You must select a NIC
redundancy and IP setting.
•
Shared LOM—The 1-Gb Ethernet ports are used to access the CIMC. 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
CIMC. You must select a NIC redundancy and IP setting.
Note
d.
Cisco Card NIC mode is currently supported only with a Cisco UCS VIC that is installed in PCIe
slot 1, 4, or 7. See also Special Considerations for Cisco UCS Virtual Interface Cards, page 3-47.
Use this utility to change the NIC redundancy to your preference. This server has three possible NIC
redundancy settings:
– None—(Available only with the Shipping NIC mode) 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 2-11 for more information.
e.
Choose whether to enable DHCP for dynamic network settings, or to enter static network settings.

Step 5
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 CIMC. The MAC address
printed on the label is the beginning of the range of six contiguous MAC addresses.
(Optional) Use this utility to make VLAN settings, and to set a default CIMC user password.
Changes to the settings take effect after approximately 45 seconds. Press F5 to refresh the screen
and wait until the new settings appear before you reboot the server in the next step.
Press F10 to save your settings and reboot the server.
If you chose to enable DHCP, the dynamically assigned IP and MAC addresses are displayed on
the console screen during bootup.
Use a browser and the IP address of the CIMC to connect to the CIMC 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 user name for the server is admin. The default password is password.
To manage the server, see the Cisco UCS C-Series Rack-Mount Server Configuration Guide or the Cisco
UCS C-Series Rack-Mount Server CLI Configuration Guide for instructions on using those interfaces.

NIC Modes and NIC Redundancy Settings
This server has the following NIC mode settings that you can choose from:
•
Note
Shared LOM EXT (default)—This is shared LOM extended mode. This is the factory default setting,
along with Active-active NIC redundancy and 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. 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 10/100 management port is used to access the CIMC. You must select a NIC
redundancy and IP setting.
•
Shared LOM—The 1-Gb Ethernet ports are used to access the CIMC. 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
CIMC. You must select a NIC redundancy and IP setting.
Note
The Cisco Card NIC mode is currently supported only with a Cisco UCS VIC that is installed in
PCIe slot 1, 4, or 7. See also Special Considerations for Cisco UCS Virtual Interface Cards,
page 3-47.
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.
•
Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.
•
Active-active—All Ethernet ports are used simultaneously.
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.

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 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 the CIMC management interface
or the Power button on the front panel.
To use the Power button, follow these steps:
Step 1
Step 2
Caution
Step 3
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:
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.
Disconnect the power cords from the power supplies in your server to completely power off the server.

Observe these drive population guidelines for optimum performance:
•
When populating drives in a drive bay module, add drives in empty slots from left to right.
•
If your server has two drive bay modules, populate all eight bays in module 1 before you populate
the module 2 bays.
•
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.

Maintaining the Server
Installing or Replacing Server Components
Replacing a Modular Drive Bay Assembly
The server allows modular configuration of the drive bays, so that you can use one or two drive bays
depending on your needs.
Each drive bay assembly includes the chassis-steel drive bay, the attached drive backplane, and a
transition card (expander or nonexpander version) that provides a connection to your RAID controllers
and the motherboard.
•
Each of the two modular chassis drive bays can hold up to eight 2.5-inch drives.
•
Each drive backplane connects to one transition card. The transition card connects the drive
backplane to the motherboard and connects to cables from your RAID controller.
•
The transition card is available in two versions:
– Nonexpander—Two internal connections to the RAID controller card are required to control
eight drives. This version includes two connectors for the cables from your RAID controller.
One connector allows control of drives 1 through 4 on the backplane. The other connector
allows control of drives 5 through 8 on the backplane.
– Expander—One internal connection to the RAID controller card is required to control eight
drives. This one connector allows control of drives 1 through 8 on the backplane.
To use more than eight 2.5-inch drives in the server (up to 16), two drive bay modules are required,
each with its own backplane and transition card.

DIMM Population Rules
Observe the following guidelines when installing or replacing DIMMs (see Figure 3-13):
•
The minimum configuration is one DIMM installed in any of CPU1’s blue sockets (A1, B1, C1, D1).
•
When populating a channel, fill the blue socket first, and then fill the black sockets (1, 2, 3).
•
The server supports one, two, or three DIMMs per channel for single- or dual-rank DIMMs.
•
The server supports only one or two quad-rank registered DIMMs (RDIMMs) per channel. The
server supports one, two, or three quad-rank load-reduced DIMMs (LRDIMMs) per channel.
•
The server supports RDIMMs or LRDIMMs. Do not mix RDIMMs and LRDIMMs in a server.
•
Unregistered DIMMs (UDIMMs) and non-ECC DIMMs are not supported.
•
For memory mirroring population rules, see Memory Mirroring Mode, page 3-25.
•
There is no requirement to install DIMMs evenly across all CPUs. However, for optimal
performance, you should populate sockets in the order that is shown in Table 3-4 for two-CPU
systems or Table 3-5 for four-CPU systems.

Memory Mirroring Mode
Note
You cannot use memory sparing and memory mirroring at the same time.
When you enable memory mirroring mode, 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.
If you choose to enable memory mirroring, you must install sets of identical DIMMs as follows:
•
For a two-CPU system, you must install DIMMs in identical sets of four. Use each set of four
identical DIMMs to populate the sockets in the order shown in Table 3-4.
•
For a four-CPU system, you must install DIMMs in identical sets of eight. Use each set of eight
identical DIMMs to populate the DIMM sockets in the order shown in Table 3-5.
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 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.
If you choose to enable lockstep channel mode, you must install sets of identical DIMMs as follows:
•
For a two-CPU system, you must install DIMMs in identical sets of four. Use each set of four
identical DIMMs to populate the sockets in the order shown in Table 3-4.
•
For a four-CPU system, you must install DIMMs in identical sets of eight. Use each set of eight
identical DIMMs to populate the DIMM sockets in the order shown in Table 3-5.

•
Replacing DIMMs, page 3-26
Identifying a Faulty DIMM
Each DIMM socket on the motherboard has a corresponding DIMM fault LED. See Internal Diagnostic
LEDs, page 3-7 for the locations of the LEDs and how to activate them.
Replacing DIMMs
To install a DIMM assembly, follow these steps:
Step 1
Caution
Step 2
Remove the DIMMs that you are replacing:
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.
If you cannot safely view and access the component, remove the server from the rack.
c.
Remove the top cover as described in “Removing and Replacing the Server Top Cover” section on
page 3-9.
d.
Remove the internal air baffle that covers the DIMM sockets.
e.
Locate the faulty DIMM and remove it from the socket on the motherboard by opening the ejector
levers at both ends of the DIMM socket.
Install a new DIMM:
Note
Before installing risers or DIMMs, refer to the population guidelines. See DIMM Performance
Guidelines and Population Rules, page 3-21.
a.
Align the new DIMM with the socket on the motherboard. Use the alignment key in the DIMM
socket to correctly orient the DIMM.
b.
Push the DIMM into the connector until it is fully seated and the ejector levers on either side of the
connector lock into place.
c.
Replace the internal air baffle, and then replace the top cover.
d.
Replace the server in the rack, replace cables, and then power on the server by pressing the Power
button.

Maintaining the Server
Installing or Replacing Server Components
Replacing CPUs and Heatsinks
The server supports up to four EP-Series CPUs. See Figure 3-13 on page 3-22 for the CPU socket
numbering.
•
The minimum configuration is two CPUs (CPU1 and CPU2).
•
The server must have either two or four CPUs to operate; you should populate CPU1 and CPU2 first,
and then populate CPU3 and CPU4.
This section contains the following topics:
•
Additional CPU-Related Parts To Order With RMA Replacement Motherboards, page 3-27
•
CPU Replacement Procedure, page 3-28
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, there are additional parts that 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 re-using the existing heatsinks:
– Heat sink cleaning kit (UCSX-HSCK=)
– Thermal grease kit for C420 (UCS-CPU-GREASE=)
– Intel CPU Pick-n-Place tool for EP CPUs (UCS-CPU-EP-PNP=)
•
Scenario 2—You are replacing the existing heatsinks:
– Heat sink (UCSC-HS-C420M3=)
– Heat sink cleaning kit (UCSX-HSCK=)
– Intel CPU Pick-n-Place tool for EP CPUs (UCS-CPU-EP-PNP=)
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 have preinstalled thermal interface material covered by a small sheet of plastic. It
is important to clean the old thermal interface material off of the CPU prior to installing the heatsinks.
Therefore, when ordering new heatsinks it is still necessary to order the heatsink cleaning kit at a
minimum.

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.
Caution
The Pick-and-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).
To install or replace a CPU heatsink and CPU, follow these steps:
Step 1
Caution
Step 2
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. You might
have to detach cables from the rear panel to provide clearance.
If you cannot safely view and access the component, remove the server from the rack.
c.
Remove the top cover as described in Removing and Replacing the Server Top Cover, page 3-9.
d.
Remove the internal air baffle that covers the CPU sockets.
Use a Number 2 Phillips-head screwdriver to loosen the four captive screws that secure the heatsink and
lift it off of the CPU.
Note
Loosen each screw evenly to avoid damaging the heatsink or CPU.
Step 3

Replacing a PCIe Card
Caution
Cisco supports all PCIe cards qualified and sold by Cisco. PCIe cards that are not qualified or sold by
Cisco are the responsibility of the customer. Although Cisco always stands behind and supports the
C-Series rack-mount servers, customers using standard, off-the-shelf, third-party cards must go to the
third-party card vendor for support if any issue with that particular third-party card occurs.
This server has seven PCIe expansion slots. See Figure 3-23 and Table 3-6 for information about the
slots. The replacement procedures differ depending on whether the PCIe slot is in a riser or on the
motherboard. This section includes the following topics:

RAID Card Firmware Compatibility
If the PCIe card that you are installing is a RAID controller card, 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

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 3-48
•
Resolving Insufficient 16-Bit I/O Space, page 3-49
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 CIMC controller, and reports the
following error in the Error Manager page of the BIOS Setup utility:
PCI OUT OF RESOURCES CONDITION:
ERROR: Insufficient PCI Resources Detected!!!
System is running with Insufficient PCI Resources!
In order to display this message some
PCI devices were set to disabled state!
It is strongly recommended to power off the system
and remove some PCI/PCI Express cards from the system!
To continue booting, proceed to <Save & Exit> Menu Option
and select Boot Device or <Discard Changes and Exit>.
WARNING: If you choose to continue booting some Operating
Systems might not be able to complete boot correctly!
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 (see Figure 3-26).

Guidelines for RAID controller booting
When the server is configured in the factory, the RAID controllers are installed in PCIe slot 3 or
slot 5 for single RAID controller configuration, or in both slot 3 and slot 5 for dual RAID controller
configuration.
If the server is configured to boot primarily from RAID storage, make sure that the option ROMs
for slot 3 or slot 5 are enabled in the BIOS, depending upon your RAID controller configuration. If
the RAID controller does not appear in the system boot order even with the option ROMs for slot 3
and slot 5 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 PXE
boot.
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 four 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 accordingly during the PCI bus
enumeration phase of the BIOS POST.

Chapter 3
Maintaining the Server
Installing or Replacing Server Components
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 CIMC WebUI 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.
Uncheck the “Enable PXE boot entry” in the vNIC properties dialog to disable the PXE boot, as
shown in Figure 3-27.

Enabling the Intel Trusted Execution Technology Feature For the TPM
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.

Maintaining the Server
Installing or Replacing Server Components
Replacing Power Supplies
The server can have one or two power supplies. When two power supplies are installed they are
redundant as 1+1.
To replace or install a power supply, follow these steps:
Note
Step 1
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.
Remove the power supply that you are replacing or a blank panel from an empty bay (see Figure 3-30):
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.
Step 2
b.
Remove the power cord from the power supply that you are replacing.
c.
Grasp the power supply handle while pinching the release lever towards 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.

RAID Card Firmware Compatibility
3. When using two expander-style transition cards, one controller can control 16 drives.
RAID Card Firmware Compatibility
If the PCIe card that you are installing is a RAID controller card, 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 Modules (RAID Backup Units)
This server supports installation of two supercap power module (SCPM) backup units. The units mount
to trays on the removable air baffle (see Replacing the Supercap Power Module (RAID Backup Unit),
page 3-51).
The SCPM is available only when using the LSI MegaRAID-CV controller cards. This module 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.
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 best practices recommendations that follow for the best
performance.

Best Practices For 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.

Restoring RAID Configuration After Replacing a RAID Controller
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.
To restore your RAID configuration to your new RAID controller, follow these steps.
Step 1
Replace your RAID controller. See Replacing a PCIe Card in a Motherboard Slot, page 3-45.
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.
Note
Step 4
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.
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 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 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.
