326 Type 8848: Installation Guide
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. Position the microprocessor over the microprocessor socket as shown in the
following illustration. Carefully press the microprocessor into the socket.
Attention:
To avoid bending the pins on the microprocessor, do not use
excessive force when pressing it into the socket.

Note: A new microprocessor comes in a kit with a heat sink.
Attention:
Do not disturb or contaminate the thermal material on the bottom
of the new heat sink. Doing so damages its heat-conducting capability and
exposes the new microprocessor to overheating.
a. Remove the heat sink from its package and remove the cover from the
bottom of the heat sink.
b. Make sure that the thermal material is still on the bottom of the heat sink,
and position the heat sink on top of the microprocessor.
c. Align the captive screws on the heat sink with the holes on the heat-sink
retention module.
d. Press firmly on the captive screws and tighten them, alternating between
screws until they are tight. Do not overtighten the screws by using excessive
force.
Attention:
If you need to remove the heat sink after installing it, note that the
thermal material might have formed a strong bond between the heat sink and
the microprocessor. Do not force the heat sink and microprocessor apart; doing
so can damage the microprocessor pins. Loosening one captive screw fully
before loosening the other captive screw helps break the bond between the
components without damaging them.
