b. Rotate the locking lever on the microprocessor socket from its closed and
locked position until it stops in the fully open position (approximately a
135° angle), as shown.
c. Rotate the microprocessor retainer on the microprocessor socket from its
closed position until it stops in the fully open position (approximately a
135° angle), as shown.
d. If a dust cover is installed over the microprocessor socket, lift the dust
cover from the socket.
e. Touch the static-protective package that contains the microprocessor to any
unpainted metal surface on the BladeCenter unit or any unpainted metal
surface on any other grounded rack component; then, remove the
microprocessor from the package.
f. Remove the dust cover from the bottom of the microprocessor.

g. Orient the triangle painted on the corner of the microprocessor with the
triangle on the microprocessor socket.
h. Carefully place the microprocessor into the microprocessor socket, using
the alignment tabs on the microprocessor with the alignment notches in
the microprocessor socket as a guide.
Attention:
v Do not press the microprocessor into the socket.
v Make sure that the microprocessor is oriented and aligned correctly in
the socket before you try to close the microprocessor retainer.
i. Carefully close the microprocessor retainer.
j. Rotate the locking lever on the microprocessor socket to the closed and
locked position. Make sure that the lever is secured in the locked position
by pressing the tab on the microprocessor socket.
9. Install a heat sink on the microprocessor.
Attention:
v Do not set down the heat sink after you remove the plastic cover.
v Do not touch the thermal material on the bottom of the heat sink. Touching
the thermal material will contaminate it. If the thermal material on the
microprocessor or heat sink becomes contaminated, contact your service
technician.
a. Remove the plastic protective cover from the bottom of the heat sink.
b. Make sure that the thermal material is still on the bottom of the heat sink;
then, align and place the heat sink on top of the microprocessor in the
retention bracket, thermal material side down. Press firmly on the heat
sink.
