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 the Cisco Integrated Management Controller (Cisco IMC) interface or the Power button on the front panel.
Step 1 Check the color of the Power Status LED (see the “Front-Panel LEDs” section).
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 remove AC power and power off the server.
You must remove the optional front bezel to access the hot-swappable drives and fan modules.
Step 1 Remove the front bezel:
a. If the bezel is locked, use the key to unlock it.
b. Slide the finger latch that is on the left side upward, and then swing the left edge of the bezel away from the server.
c. Lift the bezel from the server and set it aside.
Step 2 Replace the front bezel:
a. Align the bezel with the front of the server.
b. Set the three pegs on the right-hand edge of the bezel into the three indentations in the server.
c. Swing the left side of the bezel inward until the latch on the bezel engages with the server.
Tip You do not have to remove the cover to replace fan modules, hard drives, or power supplies.
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 with 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 chassis.
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 chassis front panel. The opening in the latch should fit over the peg that sticks up from the chassis.
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 shows the locations of the components that are discussed in this chapter. The view in Figure 3-5 is from the top down with the top cover removed.
Figure 3-5 Replaceable Component Locations
Certain components can be removed and replaced without powering off and removing AC power from the server. This type of replacement has two varieties: hot-swap and hot-plug.
– Power supplies (when 2+2 redundant)
– Memory risers (requires operating system support)
Note See the release notes for your operating system and your Cisco IMC/BIOS release for details and restrictions on hot-plugging: Cisco IMC Release Notes.
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

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 3-12 shows the DIMM sockets and how they are numbered on a memory riser.
Figure 3-12 DIMM Sockets on a Memory Riser
Observe the following guidelines when installing or replacing DIMMs:
– Table 3-5 : Two-CPU/four-riser system
– Table 3-6 : Four-CPU/eight-riser system
Table 3-5 describes the recommended population order for a two-CPU system that has four memory risers. In a two-CPU system, only CPU1 and CPU2 are populated. Only the memory risers controlled by CPU1 and CPU2 (MEM1, MEM2, MEM3, and MEM4) are populated.
|
|
|
|
|
|
|
|
|
Table 3-6 describes the recommended population order for a four-CPU system that has eight memory risers.
When you enable memory mirroring mode in the server BIOS, the memory subsystem simultaneously writes identical data to two channels. If a memory read from one of the channels returns incorrect data due to an uncorrectable memory error, the system automatically retrieves the data from the other channel. A transient or soft error in one channel does not affect the mirrored data, and operation continues.
Memory mirroring reduces the amount of memory available to the operating system by 50 percent because only one of the two populated channels provides data.
In this mode, the main memory channel from the CPU to the memory buffer runs at the same clock rate of each of the two memory subchannels from the buffer to the DIMMs, and both DIMM subchannels are accessed simultaneously for a double-width access. For example, if the CPU channel clock speed is 1600 MHz, each of the DIMM subchannels operates at 1600 MHz. For this reason, lockstep mode is referred to as 1:1. Memory lockstep mode provides protection against both single-bit and multi-bit errors. Memory lockstep allows two memory channels to work as a single channel, moving a data word two channels wide and providing eight bits of memory correction.
Lockstep channel mode requires that all four memory channels on a CPU must be populated identically with regards to size and organization. DIMM socket populations within a channel do not have to be identical but the same DIMM slot location across all four channels must be populated the same.
For example, DIMMs in sockets A1, B1, C1, and D1 must be identical. DIMMs in sockets A2, B2, C2, and D2 must be identical. However, the A1-B1-C1-D1 DIMMs do not have to be identical with the A2-B2-C2-D2 DIMMs.
The memory riser includes fault LEDs on its top panel (see Figure 3-10).
Step 1 Remove the DIMMs that you are replacing:
a. Slide the server out the front of the rack far enough so that you can remove the top cover.
b. Remove the top cover as described in Removing or Replacing the Server Top Cover.
c. Locate the memory riser that has the faulty DIMM, and then shut down and remove the riser as described in Replacing Memory Risers.
d. Locate the faulty DIMM and remove it from the socket on the riser by opening the ejector levers at both ends of the DIMM socket.
Note Before installing DIMMs, refer to the population guidelines. See DIMM Performance Guidelines and Population Rules.
a. Align the new DIMM with the socket on the riser. Use the alignment key in the DIMM socket to correctly orient the DIMM.
b. Push the DIMM into the socket until it is fully seated and the ejector levers on either side of the socket lock into place.
c. Replace the memory riser to its motherboard socket and bring it back online by using the procedure in Replacing Memory Risers.
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:
The server supports two or four CPUs. See Figure 3-12 for the CPU socket numbering.
– PCIe riser 2 (PCIe slots 6–10)
Step 1 Prepare the server for replacement:
a. Power off the server as described in Shutting Down and Powering Off the Server.
b. Slide the server out the front of the rack far enough so that you can remove the top cover.
c. Remove the top cover as described in Removing or Replacing the Server Top Cover.
Step 2 Provide clearance for removing the CPU:
a. Remove all memory risers from the server.
With power removed from the server, you do not have to shut down the memory risers before removal. Press both green riser-latch release buttons on the top of the riser (see Figure 3-11), and then lift on both riser latches at the same time.
Note It is important that each memory riser is returned to the same slot it was removed from to maintain your DIMM configuration. Label the risers or organize them in order as you remove them and set them aside on an antistatic surface.
b. Remove both PCIe risers from the server.
Lift on the retaining latch at the top of the riser until it is vertical (see Figure 3-20).
c. Remove the chassis mid-brace (see Figure 3-5).
Note The securing mechanism for the mid-brace differs, depending on when the system was produced.
– Older systems have a spring-loaded plunger that secures each end of the mid-brace. Access these plungers on the inside of the chassis. Pull inward on the spring-loaded plunger that secures each end of the mid-brace, then lift straight up.
– Newer systems have two screws that secure each end of the mid-brace. Access these screws on the outside of the chassis. Remove the two screws at each end of the mid-brace, then lift straight up.
Step 3 Use a Number 2 Phillips-head screwdriver to loosen the four captive screws that secure the heat sink, and then lift it off of the CPU.
Note Loosen each screw evenly to avoid damaging the heat sink or CPU.
Step 4 Unclip the first CPU retaining latch that is labeled with the icon, and then unclip the second retaining latch that is labeled with the icon. See Figure 3-13.
Note You must hold the first retaining latch open before you can lift the second retaining latch.
Step 5 Open the hinged CPU cover plate. See Figure 3-13.

Note Do not install an Intel Xeon v3 or v4 Series CPU unless your server meets the minimum firmware requirements, as described in Special Information For Upgrades to Intel Xeon v4 CPUs.
a. Set the Pick-n-Place tool that is holding the CPU over the empty CPU socket on the motherboard.
Note Align the arrow on the top of the tool with the registration mark (small triangle) that is stamped on the metal of the CPU socket, as shown in Figure 3-14.
b. Press the top button on the tool to set the CPU into the socket. Remove the empty tool.
c. Close the hinged CPU cover plate.
d. Clip down the CPU retaining latch with the icon first, and then clip down the CPU retaining latch with the icon. See Figure 3-13.
a. Apply the cleaning solution, which is included with the heatsink cleaning kit (shipped with spare CPUs), to the old thermal grease and let it soak for a least 15 seconds.
b. Wipe all of the old thermal grease off the old heat sink using the soft cloth that is included with the heatsink cleaning kit. Be careful to not scratch the heat sink surface.
c. Apply thermal grease from the syringe that is included with the new CPU to the top of the CPU.
Apply about half the syringe contents to the top of the CPU in the pattern that is shown in Figure 3-16.
Note If you do not have a syringe of thermal grease, you can order a spare
(Cisco PID UCS-CPU-GREASE3=).
Figure 3-16 Thermal Grease Application Pattern
d. Align the heat sink captive screws with the motherboard standoffs, and then use a Number 2 Phillips-head screwdriver to tighten the captive screws evenly.
Note Orient the heat sink so that the arrow label on the heat sink points toward the rear of the server.
Note Alternate tightening each screw evenly to avoid damaging the heat sink or CPU.
Step 11 Replace components that you removed:
a. Replace the chassis mid-brace.
Note The securing mechanism for the mid-brace differs, depending on when the system was produced.
– Older systems have a spring-loaded plunger that secures each end of the mid-brace. Access these plungers on the inside of the chassis. Pull inward on the spring-loaded plunger that secures each end of the mid-brace while you set the mid-brace in place, then release the plungers.
– Newer systems have two screws that secure each end of the mid-brace. Access these screws on the outside of the chassis. Set the mid-brace in place, then replace the two screws at each end.
b. Replace both PCIe risers to the server.
a. Replace all memory risers to the server.
Note It is important that each memory riser is returned to the same slot it was removed from to maintain your DIMM configuration.
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, some items 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.
– Heat sink cleaning kit (UCSX-HSCK=)
– Thermal grease kit for C460 M4 (UCS-CPU-GREASE3=)
– Intel CPU Pick-n-Place tool for EX CPUs (UCS-CPU-EP-PNP=)
– Heat sink cleaning kit (UCSX-HSCK=)
– Intel CPU Pick-n-Place tool for EX CPUs (UCS-CPU-EP-PNP=)
A CPU heat sink cleaning kit is good for up to four CPU and heat sink cleanings. The cleaning kit contains two bottles of solution, one to clean the CPU and heat sink of the old thermal interface material and the other to prepare the surface of the heat sink.
It is important to clean the old thermal interface material off of the CPU prior to installing the heat sinks. When you order new heat sinks, you must order the heat sink cleaning kit.
The server has a dedicated internal PCIe slot for a RAID controller card.

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 window 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 window (see Figure 3-23).
Figure 3-23 BIOS Setup Utility Advanced > PCI Configuration Window
When the server is configured in the factory, the RAID controllers are installed in PCIe slot 3 or slot 5 for a single RAID controller configuration, or in both slot 3 and slot 5 for a 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.
If the system is configured to primarily perform a 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.
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.
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 window in the Cisco IMC GUI to free up some 16-bit I/O resources. Each VIC uses a minimum 16 KB of 16-bit I/O resource, so disabling the 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 box to disable the PXE boot, as shown in Figure 3-24.
Figure 3-24 vNIC Properties Dialog Box

You can monitor and manage your Cisco Flexible Flash drives by using the Cisco IMC GUI interface or the CLI interface. See the Cisco UCS C-Series Rack-Mount Server Configuration Guide or the Cisco UCS C-Series Rack-Mount Server CLI Configuration Guide in the documentation roadmap link below.
After you install or replace a second Cisco Flexible Flash drive, you must synchronize the RAID partition by using the Cisco UCS Server Configuration Utility (SCU).
The SCU provides an option to synchronize the Hypervisor VD, configured as a RAID-1 disk. This feature is available only when both Cisco Flexible Flash drive slots are populated.
When one member slot of the SD card is corrupt, use this option to synchronize the hypervisor data across two members of the RAID-1 virtual disk. You can initiate this synchronization only if two cards are detected and the RAID-1 group is determined as unhealthy (one member is corrupt).
Step 1 Click the Hypervisor Sync icon on the toolbar of the SCU interface.
A dialog box prompts you to confirm that you want to synchronize the Hypervisor RAID.
A dialog box is displayed when the synchronization is complete.
After you click OK, the Hypervisor Sync icon on the toolbar is greyed out.
For more information about the utility, see the Cisco UCS Server Configuration Utility User Guide.
