Removing the system-board assembly - Flex System x220 Compute Node

Use this information to remove the system-board assembly.

Note: This procedure should be performed only by trained service technicians.

Before you remove the system-board assembly, complete the following steps:

Read Safety and Installation guidelines.
If the compute node is installed in an Flex System chassis, remove it (see Removing a compute node from a chassis for instructions).
Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.
Obtain the following for use during the replacement procedure (see Parts listing, Types 2585 and 7906).
- Alcohol wipes
- Thermal grease
- RFID tag (required only if the compute node came with a RFID tag attached to the bezel)

Important: When you replace the system board, you must update the compute node with the latest firmware or restore the preexisting firmware. Make sure that you have the latest firmware or a copy of the preexisting firmware before you proceed. See Updating firmware and device drivers for more information.

See System-board layouts for more information about the locations of the connectors, jumpers, and LEDs on the system board.

To remove the system-board assembly, complete the following steps:

Remove the cover (see Removing the compute node cover).
Remove all of the installed components in the following list from the system-board assembly; then, place them on a static-protective surface or install them on the new system-board assembly.
- DIMMs and air baffles (see Removing a DIMM).
- I/O expansion adapters (see Removing an I/O expansion adapter).
- Fabric connector. (see Removing a fabric connector).
- ServeRAID controller. (see Removing a ServeRAID controller).
- Hard disk drives and hard disk drive bay fillers (see Removing a hot-swap hard disk drive).
- Microprocessors, heat sinks, and microprocessor heat-sink fillers. Use the microprocessor installation tool that comes with the replacement microprocessor to remove each microprocessor from the system-board assembly and install each one immediately in the new system-board assembly (see Removing a microprocessor and heat sink and Installing a microprocessor and heat sink).
- Hard disk drive backplane (see Removing the hard disk drive backplane).
If you are replacing the old system-board assembly with a new system-board assembly, carefully remove the bezel from the old system-board assembly and install it on the new system-board assembly (see Removing the bezel and Installing the bezel). If the old bezel will not attach securely to the new system board, remove the Tag from the lower right corner of the old bezel and install it on the lower right corner of the new bezel that shipped with the new system-board assembly; then, install the new bezel on the new system-board assembly.

If you are instructed to return the system-board assembly, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
