Attention: You must ensure that the locking lever on the microprocessor socket is in the fully-open position before you insert the microprocessor in the socket. Failure to do so might result in permanent damage to the microprocessor, microprocessor socket, and microprocessor-tray assembly. 10. 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 connector 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.

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 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. 12. Remove the heat sink from its package and remove the cover from the bottom of the heat sink. Make sure that the thermal material is still on the bottom of the heat sink. Remove the release liner and orient the heat sink above the microprocessor; then, press the heat sink into place. Press firmly on the captive screws and tighten them, alternating between screws until they are tight. Do not overtighten the screws. 13. If you installed microprocessor 3 or 4, install the VRM in the associated VRM socket. a. Open the retaining clips at either end of the VRM connector. Attention: To avoid breaking the VRM retaining clips or damaging the VRM connectors, open and close the clips gently. Chapter 4. Installing options 49

Install the microprocessor:
a.
Touch the static-protective package containing the new microprocessor to

microprocessor from the package.
b.
Position the microprocessor over the microprocessor connector as shown
in the following illustration. Carefully press the microprocessor into the

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 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.
12.
Remove the heat sink from its package and remove the cover from the bottom
of the heat sink. Make sure that the thermal material is still on the bottom of
the heat sink. Remove the release liner and orient the heat sink above the
microprocessor; then, press the heat sink into place. Press firmly on the
captive screws and tighten them, alternating between screws until they are
tight. Do not overtighten the screws.
13.
If you installed microprocessor 3 or 4, install the VRM in the associated VRM
socket.
a.
Open the retaining clips at either end of the VRM connector.
Attention:
To avoid breaking the VRM retaining clips or damaging the
VRM connectors, open and close the clips gently.
