This section describes how to prepare for component installation, and it includes the following topics:
The following equipment is used to perform the procedures in this chapter:
The server can run in two power modes:
You can invoke a graceful shutdown or a hard shutdown by using either of the following methods:
Step 1 Check the color of the Power Status LED (see the “Front Panel LEDs” section).
Step 2 Invoke either a graceful shutdown or a hard shutdown:
Step 3 Disconnect the power cords from the power supplies in your server to completely power off the server.
Step 1 Remove the top cover (see Figure 3-4).
a. If the cover latch is locked, use a screwdriver to turn the lock 90-degrees counterclockwise to unlock 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.
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 position. The cover is pushed forward to the closed position as you push down the latch.
c. If desired, lock the latch by using a screwdriver to turn the lock 90-degrees clockwise.

This section includes the following topics:
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.
This section describes the type of memory that the server requires and its effect on performance. The section includes the following topics:
Figure 3-16 shows the numbering of the DIMM sockets and CPUs.
Figure 3-16 CPUs and DIMM Socket Numbering on Motherboard
Observe the following guidelines when installing or replacing DIMMs:
– CPU1 supports channels A, B, C, and D.
– CPU2 supports channels E, F, G, and H.
– 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).
– 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
The Intel E5-2600 CPUs within the server support memory mirroring only when an even number of channels are populated with DIMMs. If one or three channels are populated with DIMMs, memory mirroring is automatically disabled. Furthermore, if memory mirroring is used, DRAM size is reduced by 50 percent for reasons of reliability.
For details on populating recommended memory mirroring configurations, see the specification sheet for the server:
When you enable lockstep channel mode, each memory access is a 128-bit data access that spans four channels.
Lockstep channel mode requires that all four memory channels on a CPU must be populated identically with regard to size and organization. DIMM socket populations within a channel (for example, A1, A2, A3) do not have to be identical but the same DIMM slot location across all four channels must be populated the same.
For example, DIMMs in sockets A1, B1, C1, and D1 must be identical. DIMMs in sockets A2, B2, C2, and D2 must be identical. However, the A1-B1-C1-D1 DIMMs do not have to be identical with the A2-B2-C2-D2 DIMMs.
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.
Step 1 Power off the server as described in Shutting Down and Powering Off the Server.
Step 2 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.
Step 3 Remove the top cover as described in Removing and Replacing the Server Top Cover.
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.
Note Before installing DIMMs, see the population guidelines. See Memory Performance Guidelines and Population Rules.
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 10 Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.
The minimum software and firmware versions required for the server to support Intel v4 CPUs are as follows:
|
|
---|---|
Note Cisco UCS Manager Release 2.2(4) introduced a server pack feature that allows Intel v4 CPUs to run with Cisco UCS Manager Release 2.2(4) or later.
The UCS Manager Capability Catalog must be updated to 2.2(7c) or later.
The server Cisco IMC/BIOS must be running the minimum version or later as described in Table 3-7.
Do one of the following actions:
This server has two CPU sockets. Each CPU supports four DIMM channels (12 DIMM sockets). See Figure 3-16.
– 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.
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.
Step 2 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.
Step 3 Remove the top cover as described in Removing and Replacing the Server Top Cover.
Step 4 Remove the plastic air baffle that sits over the CPUs.
Step 5 Remove the heatsink that you are replacing:
a. Use a Number 2 Phillips-head screwdriver to loosen the four captive screws that secure the heatsink.
Note Alternate loosening each screw evenly to avoid damaging the heatsink or CPU.
b. Lift the heatsink off of the CPU.
Step 6 Open the CPU retaining mechanism:
a. Unclip the first retaining latch labeled with the icon, and then unclip the second retaining latch labeled with the icon. See Figure 3-17.

a. Apply the cleaning solution, which is included with the heatsink cleaning kit (UCSX-HSCK=, shipped with spare CPUs), to the old thermal grease on the heatsink and CPU and let it soak for a least 15 seconds.
b. Wipe all of the old thermal grease off the old heat sink and CPU using the soft cloth that is included with the heatsink cleaning kit. Be careful to not scratch the heat sink surface.
Note New heatsinks come with a pre-applied pad of thermal grease. If you are reusing a heatsink, you must apply thermal grease from a syringe (UCS-CPU-GREASE3=).
c. Align the four heatsink captive screws with the motherboard standoffs, and then use a Number 2 Phillips-head screwdriver to tighten the captive screws evenly.
Note Alternate tightening each screw evenly to avoid damaging the heatsink or CPU.
Step 10 Replace the air baffle.
Step 11 Replace the top cover.
Step 12 Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.
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.
– Heat sink cleaning kit (UCSX-HSCK=)
– Thermal grease kit for C240 M4 (UCS-CPU-GREASE3=)
– Heat sink cleaning kit (UCSX-HSCK=)
A CPU heatsink cleaning kit is good for up to four CPU and heatsink cleanings. The cleaning kit contains two bottles of solution, one to clean the CPU and heatsink of old thermal interface material and the other to prepare the surface of the heatsink.
New heatsink spares come with a pre-applied pad of thermal grease. It is important to clean the old thermal grease off of the CPU prior to installing the heatsinks. Therefore, when you are ordering new heatsinks, you must order the heatsink cleaning kit.
The server uses a SATA interposer board and cable to connect the embedded RAID (PCH SATA) controller on the motherboard to the drive backplane. See Figure 3-19 for the socket location.
Note The SATA interposer board and embedded RAID can be used only with the SFF, 8-drive backplane version of the server. It does not operate with an expander. You cannot use the embedded RAID controller and a hardware RAID controller card at the same time.
See Embedded SATA RAID Controller for more information about using the embedded RAID controller and options.
Step 1 Power off the server as described in the Shutting Down and Powering Off the Server.
Step 2 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.
Step 3 Remove the top cover as described in Removing and Replacing the Server Top Cover.
Step 4 Remove the plastic air baffle that sits over the CPUs to gain access to the interposer cables.
Step 5 Remove PCIe riser 1 from the server to provide clearance. See Replacing a PCIe Riser.

The server has an internal, dedicated PCIe slot on the motherboard for a Cisco modular RAID controller card (see Figure 3-20).
Note You cannot use a hardware RAID controller card and the embedded RAID controller at the same time. See RAID Controller Considerations for details about RAID support.
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

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:
The topics in this section provide guidelines for resolving the issues related to these limited resources:
The system has very limited memory to execute PCIe legacy option ROMs, so when a large number of PCIe add-on cards are installed in the server, the system BIOS might not able to execute all of the option ROMs. The system BIOS loads and executes the option ROMs in the order that the PCIe cards are enumerated (slot 1, slot 2, slot 3, and so on).
If the system BIOS does not have sufficient memory space to load any PCIe option ROM, it skips loading that option ROM, reports a system event log (SEL) event to the Cisco IMC controller and reports the following error in the Error Manager page of the BIOS Setup utility:
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.
If the server is configured to boot primarily from RAID storage, make sure that the option ROMs for the slots where your RAID controllers installed are enabled in the BIOS, depending on your RAID controller configuration.
If the RAID controller does not appear in the system boot order even with the option ROMs for those slots are 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.
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.
The system has only 64 KB of legacy 16-bit I/O resources available. This 64 KB of I/O space is divided between the CPUs in the system because the PCIe controller is integrated into the CPUs. This server BIOS has the capability to dynamically detect the 16-bit I/O resource requirement for each CPU and then balance the 16-bit I/O resource allocation between the CPUs during the PCI bus enumeration phase of the BIOS POST.
When a large number of PCIe cards are installed in the system, the system BIOS might not have sufficient I/O space for some PCIe devices. If the system BIOS is not able to allocate the required I/O resources for any PCIe devices, the following symptoms have been observed:
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 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.
Note SATA boot drives are supported only in the SFF 24-drive and LFF 12-drive versions of the server.
The SFF 24-drive and LFF 12-drive versions of the server can support two solid-state SATA boot drives, but only when the PCIe riser 1C option is installed (UCSC-PCI-1C-240M4). This version of riser 1 has two SATA boot drive connectors in place of slot 3.
Note The two internal SATA boot drives can be mirrored in a RAID 1 configuration when managed by the embedded RAID controller or in advanced host controller interface (AHCI) mode through your Windows or Linux operating system. The SATA mode must be enabled and selected in the BIOS, as described in Enabling the Embedded RAID Controller in the BIOS.
Step 1 Shut down and power off the server as described in Shutting Down and Powering Off the Server.
Step 2 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.
Step 3 Remove the top cover as described in Removing and Replacing the Server Top Cover.
Step 4 Remove PCIe riser 1C from the server:
a. Lift straight up on both ends of the riser to disengage its circuit board from the socket on the motherboard. Set the riser on an antistatic mat.
b. On the bottom of the riser, loosen the single thumbscrew that holds the securing plate. See Figure 3-29.
c. Swing open the securing plate and remove it from the riser to provide access.
Step 5 Remove an existing SATA boot drive from PCIe riser 1C.
Grasp the carrier-tabs on each side of the boot drive and pinch them together as you pull the boot drive from its cage and the socket on the PCIe riser.
Step 6 Install a new SATA boot drive to PCIe riser 1C.
a. Grasp the two carrier-tabs on either side of the boot drive and pinch them together as you insert the drive into the cage on the riser.
b. Push the drive straight into the cage to engage it with the socket on the riser. Stop when the carrier-tabs click and lock into place on the cage.
Step 7 Return PCIe riser 1C to the server:
a. Return the securing plate to the riser. Insert the two hinge-tabs into the two slots on the riser, and then swing the securing plate closed.
b. Tighten the single thumbscrew that holds the securing plate.
c. Position the PCIe riser over its socket on the motherboard and over its alignment features in the chassis (see Figure 3-27).
d. Carefully push down on both ends of the PCIe riser to fully engage its circuit board connector with the socket on the motherboard.
Step 9 Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.
Step 10 Set the boot order for these SATA boot drives in the server BIOS as desired:
a. Boot the server and press F2 when prompted to enter the BIOS Setup Utility.

The trusted platform module (TPM) is a small circuit board that connects to a motherboard socket and is secured by a one-way screw.
Trusted platform module (TPM) version 2.0 is supported on Intel v3- or Intel v4-based platforms.
If there is an existing TPM 1.2 installed in the server, you cannot upgrade to TPM 2.0.
If there is no existing TPM in the server, you can install TPM 2.0. You must first upgrade to Intel v4 code, regardless of whether the installed CPU is Intel v3 or v4. TPM 2.0 requires Intel v4 code or later.
Note If the TPM 2.0 becomes unresponsive, reboot the server.

To release the connector block from the power supply, push the orange plastic button on the top of the connector inward toward the power supply and pull the connector block out.
Step 3 Strip 15mm (.59 inches) of insulation off the DC wires that you will use.
Note The recommended wire gauge is 8 AWG. The minimum wire gauge is 10 AWG.
Step 4 Orient the connector as shown in Figure 3-33, with the orange plastic button toward the top.
Step 5 Use a small screwdriver to depress the spring-loaded wire retainer lever on the lower spring-cage wire connector. Insert your green (ground) wire into the aperture and then release the lever.
Step 6 Use a small screwdriver to depress the wire retainer lever on the middle spring-cage wire connector. Insert your black (DC negative) wire into the aperture and then release the lever.
Step 7 Use a small screwdriver to depress the wire retainer lever on the upper spring-cage wire connector. Insert your red (DC positive) wire into the aperture and then release the lever.
Step 8 Insert the connector block back into the power supply. Make sure that your red (DC positive) wire aligns with the power supply label, “+ DC”.
Step 9 See Installation Grounding for additional information about chassis grounding.

The AC power supplies have internal grounding and so no additional grounding is required when the supported AC power cords are used.
When using a DC power supply, additional grounding of the server chassis to the earth ground of the rack is available. Screw holes for use with your grounding lugs and grounding wires are supplied on the chassis rear panel.
Note The grounding points on the chassis are sized for M5 screws. The grounding points are spaced at 0.625 inches (15.86 mm). You must provide your own screws, grounding lug, and grounding wire. The grounding lug required is a Panduit LCD10-14AF-L or equivalent. The grounding cable that you provide must be 14 AWG (2 mm), minimum 60° C wire, or as permitted by the local code.
See Figure 3-31 for the location of the grounding lug screw-holes on the chassis rear panel.
The server can use an mLOM card to provide additional connectivity. The mLOM card socket remains powered when the server is in 12 V standby power mode and it supports the network communications services (NCSI) protocol.
Step 1 Power off the server as described in Shutting Down and Powering Off the Server.
Step 2 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.
Step 3 Remove the top cover as described in Removing and Replacing the Server Top Cover.
Step 4 Remove PCIe riser 1 to provide clearance. See Replacing a PCIe Riser for instructions.
Step 5 Remove any existing mLOM card or a blanking panel (see Figure 3-34):
a. Loosen the single thumbscrew that secures the mLOM card to the chassis floor.
b. Slide the mLOM card horizontally to disengage its connector from the motherboard socket.
Step 6 Install a new mLOM card:
a. Set the mLOM card on the chassis floor so that its connector is aligned with the motherboard socket and its thumbscrew is aligned with the standoff on the chassis floor.
b. Push the card’s connector into the motherboard socket horizontally.
c. Tighten the thumbscrew to secure the card to the chassis floor.
Step 7 Return PCIe riser 1 to the server. See Replacing a PCIe Riser for instructions.
Step 9 Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.

Note The following procedures use a recovery.cap
recovery file. In Cisco IMC releases 3.0(1) and later, this recovery file has been renamed bios.cap
.
Depending on which stage the BIOS becomes corrupted, you might see different behavior.
Note As indicated by the message shown above, there are two procedures for recovering the BIOS. Try procedure 1 first. If that procedure does not recover the BIOS, use procedure 2.
Step 1 Download the BIOS update package and extract it to a temporary location.
Step 2 Copy the contents of the extracted recovery folder to the root directory of a USB thumb drive. The recovery folder contains the recovery.cap
(or bios.cap
) file that is required in this procedure.
Note The recovery.cap
(or bios.cap
) file must be in the root directory of the USB thumb drive. Do not rename this file. The USB thumb drive must be formatted with either FAT16 or FAT32 file systems.
Step 3 Insert the USB thumb drive into a USB port on the server.
Step 5 Return the server to main power mode by pressing the Power button on the front panel.
The server boots with the updated BIOS boot block. When the BIOS detects a valid recovery.cap
(or bios.cap
) file on the USB thumb drive, it displays this message:
Step 6 Wait for server to complete the BIOS update, and then remove the USB thumb drive from the server.
Note During the BIOS update, Cisco IMC shuts down the server and the screen goes blank for about 10 minutes. Do not unplug the power cords during this update. Cisco IMC powers on the server after the update is complete.
See Figure 3-35 for the location of the SW8 block of DIP switches.
Step 1 Download the BIOS update package and extract it to a temporary location.
Step 2 Copy the contents of the extracted recovery folder to the root directory of a USB thumb drive. The recovery folder contains the recovery.cap (or ios.cap) file that is required in this procedure.
Note The recovery.cap (or bios.cap) file must be in the root directory of the USB thumb drive. Do not rename this file. The USB thumb drive must be formatted with either FAT16 or FAT32 file systems.
Step 3 Power off the server as described in Shutting Down and Powering Off the Server.
