Removing the system-board assembly - BladeCenter HX5

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 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.

Note
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:

  1. Before you begin, read Safety and Installation guidelines.
  2. If the blade server is installed in a BladeCenter chassis, remove it (see Removing the blade server from the BladeCenter chassis for instructions).
  3. Carefully lay the blade server on a flat, static-protective surface.
  4. If an optional expansion unit is installed, remove the expansion unit (see Removing an expansion unit for instructions).
    Note
    Optional expansion units are not supported when a IBM MAX5 expansion blade is installed.
  5. If you are removing the system-board assembly from a blade server that is the bottom blade server in a scalable blade complex, disassemble the blade complex (see Disassembling a scalable blade complex for instructions).
  6. If an IBM MAX5 expansion blade is installed, remove it (see Removing an IBM MAX5 expansion blade for instructions).
  7. Open the blade server cover (see Removing the blade server cover for instructions).
  8. Remove the access panel if you have the standard heat sinks installed.
    Note
    If you have the tall heat sinks installed, you do not need to remove the access panel.

    1. Using a screwdriver or a coin, turn each of the screws toward the middle of the blade server until they are in the unlocked position.
    2. While you lift the back of the access panel, slide the panel away from the bezel.
  9. 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.
  10. Use an alcohol wipe to remove any thermal grease from the tabs on the microprocessor retainer frame on the old system board.
