About this task
Attention:
v Always use the microprocessor installation tool to remove a microprocessor.
Failing to use the microprocessor installation tool may damage the
microprocessor sockets on the system board. Any damage to the microprocessor
sockets may require replacing the system board.
v Microprocessors are to be removed only by trained service technicians.
v Do not allow the thermal grease on the microprocessor and heat sink to come in
contact with anything. Contact with any surface can compromise the thermal
grease and the microprocessor socket.
v Dropping the microprocessor during installation or removal can damage the
contacts.
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.
To remove a microprocessor and heat sink, complete the following steps:
Procedure
1. Read the Safety information, “Handling static-sensitive devices” on page 96,
and “Installation guidelines” on page 94.
2. Follow the procedure in “Removing a file module and disconnecting power”
on page 92 to suspend the file module from the cluster and shut it down, and
then disconnect all power cords and external cables.
3. Remove the cover (see “Removing the cover” on page 123).
4. Remove the following components, if necessary:
v PCI riser-card assembly 1 (see “Removing a PCI riser-card assembly” on
page 141)
v DIMM air baffle (see “Removing the air baffle” on page 137)
5. Disconnect any cables that impede access to the heat sink and the
microprocessor.
6. Locate the microprocessor to be removed (see System-board internal
connectors).
7. Remove the heat sink.
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, you must wipe off the
contaminated thermal material on the microprocessor or heat sink with the
alcohol wipes and reapply clean thermal grease to the heat sink.
a. Open the heat sink release lever to the fully open position.
b. Lift the heat sink out of the file module. After removal, place the heat sink
(with the thermal grease side up) on a clean, flat surface.
