Removing and replacing FRUs
FRUs must be replaced or installed only by trained service technicians.
The illustrations in this document might differ slightly from the hardware.
Removing a microprocessor
Attention:
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 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:
Microprocessor
Heat sink
Heat-sink
installation
label
Alignment indicator
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 39.
2. Turn off the server and peripheral devices and disconnect all power cords; then,
remove the cover (see “Removing the cover” on page 42).
3. Remove the heat sink. Loosen two captive screws on alternate sides of the heat
sink fully before loosening the other two captive screws (this helps to break the
bond between the heat sink and the microprocessor). After the captive screws
are loosened, remove the heat sink.
