Attention: When you handle static-sensitive devices, take precautions to avoid dam-
age from static electricity. For details on handling these devices, see "Handling static-
sensitive devices" on page 4.
4. If you are installing a new microprocessor, go to step 5; otherwise, continue:
Captive screws
VRM 3
Microprocessor
locking lever
5. Install the VRM in the slot adjacent to the microprocessor socket.

Installation Guide
SMP Expansion Modules, remove the top module to gain access to the
bottom or lower SMP 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 microproces-
sor, note that the heat-conducting grease between the heat sink and the
microprocessor might have formed a strong bond. Do not force the compo-
nents apart; doing so can damage the microprocessor pins. If the heat sink
does not separate from the microprocessor easily, loosen one heat sink cap-
tive 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 instal-
lations in your server and can be discarded. When installing a new microproces-
sor, you must install the VRM that came in the kit.
a. If you are replacing a failed VRM:
