Removing the system-board assembly

Use this information to remove the system-board assembly from the blade server.

Attention: The system-board assembly is a field-replaceable unit (FRU) and must be replaced by a trained service technician. To contact an IBM service representative, see Hardware service and support.

When you replace the system board, you will replace the system board and blade base as one assembly. After replacement, you must either update the blade server with the latest firmware or restore the pre-existing firmware that the customer provides on a diskette or CD image.

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

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

Before you begin, read Safety and Installation guidelines.
If the blade server is installed in a BladeCenter® unit, remove it (see Removing the blade server from the BladeCenter unit for instructions).
Carefully lay the blade server on a flat, static-protective surface.
Remove the blade server cover (see Removing the blade server cover).
If an optional expansion unit is installed, remove the expansion unit (see Removing an optional expansion unit).
Remove the blade server bezel assembly (see Removing the bezel assembly).
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.
- cKVM card. See Removing a concurrent KVM card.
- DIMMs. See Removing a memory module.
- I/O expansion card. See Removing an I/O expansion card, Removing a storage interface card, and Removing a high-speed expansion card.
- Microprocessors and heat sinks. See Removing a microprocessor and heat sink.
- Storage drives. See Removing a hot-swap storage drive or Removing a fixed-storage drive.
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.
