12. Reconnect the power cables to the connectors on the system board and secure
the power cables with any cable clips on the chassis.
13.
Reconnect the power cable from the RAID battery to the ServeRAID adapter,
if you have removed it.
14. Reinstall the fan assembly (see “Installing the fan assembly” on page 105).
15. Reinstall the air baffle (see “Replacing the air baffle” on page 336).
If you have other devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 104.
Removing a microprocessor and heat sink
Attention:
v
Be extremely careful, the pins on the socket are fragile. Any damage to the pins
may require replacing the system board.
v
Do not allow the thermal grease on the microprocessor and heat sink to come in
contact with anything.
v
Removing the heat sink from the microprocessor destroys the even distribution
of the thermal grease and requires replacing the thermal grease.
v
Do not touch the microprocessor contacts; handle the microprocessor by the
edges only. Contaminants on the microprocessor contacts, such as oil from your
skin, can cause connection failures between the contacts and the socket.
v Use the microprocessor installation tool that came with the new microprocessor
to remove and install the microprocessor. Failure to use the microprocessor tool
may cause damage to the pins on the socket. Any damage to the pins may
require replacing the system board.
To remove a microprocessor and heat sink, complete the following steps:
1. Read the safety information that begins on page Safety and “Installation
guidelines” on page 36.
2. Turn off the server (see “Turning off the server” on page 24) and all attached
peripheral devices. Disconnect all power cords; then, disconnect all external
cables as necessary to replace the device.
3. Remove the left side cover (see “Removing the left-side cover” on page 39).
4. Disconnect any cables that impede access to the heat sink and microprocessor.
5.
Remove the air baffle (see “Removing the air baffle” on page 41).
6. Loosen the screws on the heat sink with a screwdriver by the order as the
label showed. If possible, each screw should be rotated two full rotations at a
time.
7. Gently pull the heat sink off the microprocessor. Lift the heat sink out of the
server. If the heat sink sticks to the microprocessor, slightly twist the heat sink
back and forth to break the seal. After removal, place the heat sink on its side
on a clean, flat surface.
Note: Removing the heat sink from the microprocessor destroys the even
distribution of the thermal grease and requires replacing the thermal grease.
