10. Pull the microprocessor out of the socket.
To install a microprocessor and heat sink, reverse the preceding steps.
Important: When installing a microprocessor make sure that the orientation

Attention: Before attempting to remove the heat sink from the
microprocessor, note that the heat-conducting grease between the heat sink
and the microprocessor might have formed a strong bond. Do not force the
components apart; doing so can damage the microprocessor pins. Loosening
one screw fully before loosening the other screw will help to break the thermal
bond that adheres the heat sink to the microprocessor.
Important: Be careful when handling the adhesive material on the
microprocessor. If the adhesive material on the microprocessor will
be reused, do not contaminate it. If replacement adhesive material
is provided with the replacement part, be sure to remove all traces
of existing adhesive material from the microprocessor before
applying the new adhesive material.
8. Lift the fan sink up and out of the server.
Note: It might be necessary to gently twist the heat sink to loosen it from the
microprocessor.
9. Rotate the locking lever on the microprocessor socket from its closed and
locked position until it stops or clicks in the fully open position.
Attention: You must make sure that the locking lever on the microprocessor
socket is in the fully open position before you insert the microprocessor into
the socket. Failure to do so might result in permanent damage to the
microprocessor, microprocessor socket, and microprocessor board.
