Attention: When you handle static-sensitive devices, take precautions to avoid
damage from static electricity. For details on handling these devices, see "Handling
static-sensitive devices" on page 6.
4. If you are installing a new microprocessor, go to step 5; otherwise, continue:
5. Install the VRM in the slot adjacent to the microprocessor socket.

SMP Expansion Modules, remove the top module to gain access to the
bottom or lower SMP Expansion Module.
a. Verify that you have selected the correct microprocessor to be replaced. The
LED next to the failing microprocessor will be on.
Attention: Before attempting to remove the heat sink from the
microprocessor, note that the heat-conducting grease between the heat sink
and the microprocessor might have formed a strong bond. Do not force the
components apart; doing so can damage the microprocessor pins. If the heat
sink does not separate from the microprocessor easily, loosen one heat sink
captive mounting screw first. This allows one corner of the heat sink to be
lifted off of the microprocessor; then, you can loosen the other captive
mounting screw and remove the heat sink.

b. Using a screwdriver, loosen the two captive mounting screws on the heat sink,
alternating between screws until they release from the SMP board; then,
remove the heat sink.
c. Lift the microprocessor locking lever to the open position and remove the
microprocessor.
Attention: If you are installing an additional microprocessor, note that the new
microprocessor comes in a kit with a VRM. Some microprocessor options contain
a VRM with a clip to secure the VRM in the slot. This clip is not needed for
installations in your server and can be discarded. When installing a new
microprocessor, you must install the VRM that came in the kit.
a. If you are replacing a failed VRM:
1) Verify that you have selected the correct VRM to be replaced. The LED
next to the failing VRM will be on.
2) Grasp the VRM at both upper corners and lift it out of the slot.
