Removing and Replacing a Processor

This section provides information about removing and replacing a processor. The processors are
located on the system board, which is accessible by removing the top metal cover.

WARNING!

Ensure that the server is powered off, and all power sources have been disconnected

from the server before removing or replacing a processor.

Voltages are present at various locations within the server when an AC power source is connected.
This voltage is present even when the main power switch is in the off position.

Failure to observe this warning could result in personal injury or damage to equipment

CAUTION:

Failure to properly complete the steps in this procedure will result in erratic server

behavior or server failure.

Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD safety
precautions could result in damage to the server.

The processors are located on the system board. The system board can support either one or two
processors. The CPU 0 slot is located on the right side of the system board, and the CPU 1 slot
is located to the left of CPU 0 near the DIMMs. For the processor locations, see

Figure 4-25

.

CAUTION:

Ensure that the cache size is identical for all processors. Failure to observe this

caution will result in server failure.

Ensure that all processors are rated for use at the same speed. Failure to observe this caution will
result in performance degradation.

Valid processors are identified in

Appendix A (page 117)
