Complete the following steps to remove a microprocessor and heat sink:
1. Turn off the server and all attached peripheral devices.
2. Disconnect all power cords and external cables from the back of the server.
3. If necessary, remove the server from the rack; then, remove the server cover
(see “Removing the cover” on page 18).
4. Loosen one captive screw fully before loosening the other captive screw (this
helps to break the bond between the heat sink and the microprocessor). After
the captive screws are loosened, then remove the heat sink.
Note: It might be necessary to gently twist the heat sink to loosen it from the
microprocessor.
Important: Be careful when handling the microprocessor and heat sink. If the
thermal grease between the microprocessor and heat sink will be
reused, do not contaminate it. If replacement thermal grease is
provided with the replacement part, be sure to remove all traces of
existing thermal grease from the remaining part before applying the
new thermal grease.
5. Rotate the microprocessor socket lever arm upward to its maximum vertical
position (135°).
6. Remove the microprocessor from the socket.
