Air-baffle assembly cover Note: It might be easier to turn the server on its side and remove the air baffle to access the microprocessors. 3. Identify the microprocessor to be removed. 4. Remove the heat sink: a. Loosen one captive screw fully; then, loosen the other captive screw. Attention: Loosening one screw fully before loosening the other screw will help to break the thermal bond that adheres the heat sink to the microprocessor. b. Pull the heat sink off of the microprocessor. 5. Rotate the locking lever on the microprocessor socket from its closed and locked position until it stops or clicks in the fully open position (approximately 135° angle), as shown. Then, see the documentation provided with the microprocessor option for complete installation instructions. 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 system board.

sink
to
the
microprocessor.
b.
Pull
the
heat
sink
off
of
the
microprocessor.
5.
Rotate
the
locking
lever
on
the
microprocessor
socket
from
its
closed
and
locked
position
until
it
stops
or
