Processor-board assembly

This section contains instructions for removing the processor-board assembly, the microprocessor and power module, and the processor-board VRM.

Note: When replacing the processor-board assembly, you must either update the server with the latest firmware or restore the pre-existing firmware that the customer provides on a CD image. See “Updating the firmware” on page 39.

Before you begin:

vRead “Installation guidelines” on page 77.

vRead the safety notices at “Safety notices (multilingual translations)” on page 201.

vRead “Handling static-sensitive devices” on page 200.

1.Turn off the server (see “Turning off the server” on page 8), and disconnect all power cords and external cables.

2.Open the cover (see “Opening the cover” on page 88).

3.Pull open the memory-board retaining latches, and remove the memory-board assembly. See “Memory board” on page 115 for details.
