6. 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. 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: The microprocessor-release lever is on the side of the socket that faces
the rear of the server.
7. Close the microprocessor release lever to secure the microprocessor.
Attention:
v 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.
v If you need to remove the heat sink after installing it, note that the thermal
material may 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.
8. Remove the heat sink from its package and remove the cover from the bottom
of the heat sink. Ensure that the thermal material is still on the bottom of the
