System x3530 M4 Type 7160: Installation and Service Guide
Attention:
v Do not press the microprocessor into the socket.
v Do not touch exposed pins of the microprocessor socket. The pins on the
socket are fragile. Any damage to the pins may require replacing the
system board.
v Make sure that the microprocessor is oriented and aligned correctly in
the socket before you try to close the microprocessor retainer.
v Do not touch the thermal material on the bottom of the heat sink or on
top of the microprocessor. Touching the thermal material will
contaminate it and destroys its even distribution. If the thermal material
on the microprocessor or heat sink becomes contaminated, you must
replace the thermal grease.
c. Take off the microprocessor installation tool from the microprocessor
socket and close the microprocessor bracket frame.
d. Carefully close the microprocessor release lever to the closed position to
secure the microprocessor in the socket.
6. Install the heat sink that comes with 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.
Attention: Do not touch the thermal grease on the bottom of the heat
sink after you remove the plastic cover. Touching the thermal grease will
contaminate it. See Thermal grease for more information.
b. Align the screws on the heat sink with the screw holes on the system
board; then, place the heat sink on the microprocessor with the
thermal-grease side down.
