Notes:
a. The new microprocessor comes in a kit with a VRM and a heat sink.
b. If you are replacing a failed microprocessor, verify that you have selected the
correct microprocessor to be replaced. The LED next to the failing micropro-
cessor will be on. Remove the microprocessor heat sink (two thumbscrews).
c. If you are installing an additional microprocessor, first install a VRM in the slot
adjacent to the microprocessor socket you have selected and remove the pro-
tective tape from the microprocessor socket.
4. Install the microprocessor:
a. Touch the static-protective package containing the new microprocessor to any
unpainted metal surface on the server; then, remove the microprocessor from
the package.
b. Lift the locking lever on the socket to permit plugging in the microprocessor.
c. Align the triangle icon on the microprocessor with the triangle icon on the
socket and press the microprocessor gently into the socket.
Attention: Make sure that the microprocessor is aligned correctly before you
proceed. To avoid bending the pins on the microprocessor, do not use exces-
sive force when pressing it into the socket.
d. Close the locking lever to secure the microprocessor.
5. Install the microprocessor heat sink.
Attention: Do not disturb or contaminate the heat-conducting grease on the bot-
tom of the new heat sink. Doing so damages its heat-conducting capability and
exposes the new microprocessor to overheating.
