Use this information to replace a microprocessor and heat
sink.
The following notes describe the type of microprocessor
that the server supports and other information that you must consider
when you install a microprocessor and heat sink:
Read the safety information in Safety and Installation guidelines.
If you are replacing a server component in the server,
you need to turn off the server and peripheral devices, and disconnect
the power cords and all external cables.
To install a microprocessor and heat sink, complete the
following steps.
- Carefully turn the server on its side so that it is lying
flat, with the cover facing up.
Attention:
- When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling these
devices, see Handling static-sensitive devices.
- The microprocessor contacts are fragile; handle the microprocessor
very carefully. Do not touch the microprocessor contacts with your
skin.
- The microprocessor fits only one way on the socket.
- Align the microprocessor with the socket (note the alignment
mark and the position of the notches); then, carefully place the microprocessor
on the socket, close the microprocessor bracket frame, and close the
microprocessor release latch.

- Gently lower the heat sink on the microprocessor.
- Align the screw holes on the heat sink with the holes on
the system board.

- Install the heat sink on the microprocessor.
Attention: 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.
- Make sure that the thermal material is still on the
bottom of the heat sink; then, align the heat sink so that the arrows
on the label point toward the DIMMs and place the heat sink on top
of the microprocessor, thermal material side down.
- Align the screws on the heat sink with the screw holes
on the system board.
- Tighten the screws with a screwdriver, alternating among
the screws until they are tight. If possible, each screw should be
rotated two full rotations at a time. Repeat until the screws are
tight. Do not overtighten the screws by using excessive force.
Attention: When the two screws that are closer to
the rear of the server are tightened, the screw heads are not level
with the surface of the heat sink. Do not overtighten the screws by
using excessive force.
- Reinstall the air baffle if it was removed before (see Replacing the air baffle).
- Reinstall the cover (see Replacing the cover).
- Slide the server into the rack.
- Reconnect the power cords and cables that you removed.
- Turn on all attached devices and the server.
