Removing the system-board assembly

Use this information to remove the system-board assembly from the blade server. For related information for the DataPower Integration Blade XI50B blade appliance, see the WebSphere DataPower Integration Blade X150B pdsg Addendum document available on the IBM Web site at

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 Blade server 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:

  1. Before you begin, read Safety and Installation guidelines.
  2. If the blade server is installed in a BladeCenter unit, remove it (see Removing the blade server from the BladeCenter unit for instructions).
  3. Carefully lay the blade server on a flat, static-protective surface.
  4. Remove the blade server cover (see Removing the blade server cover).
  5. If an optional expansion unit is installed, remove the expansion unit (see Removing an optional expansion unit).
  6. 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.
  7. The new system-board assembly comes with an IBM Repair Identification (RID) tag. Using a ball point pen, transfer the machine type and serial number from the old system-board assembly to the two labels on the IBM Repair Identification (RID) tag provided with the new system-board assembly; then, place label 1 (larger label) on the base of the planar and label 2 (smaller label) on the bottom side of the control panel.
  8. 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.
