Removing and replacing FRUs
FRUs must be installed only by trained service technicians.
The illustrations in this document might differ slightly from your hardware.
Removing a microprocessor and heat sink
Notes:
v If you are not replacing a defective heat sink or microprocessor, the thermal
material on the heat sink and microprocessor will remain effective if you carefully
handle the heat sink and microprocessor. When removing or installing these
components, do not touch the thermal material or allow it to become
contaminated.
v
The heat-sink FRU is packaged with the thermal material applied to the
underside. This thermal material is not available as a separate FRU. The heat
sink must be replaced when new thermal material is required, such as when a
defective microprocessor is replaced or if the thermal material is contaminated or
has come in contact with another object other than its paired microprocessor.
v
The microprocessor FRU for this system board includes a heat sink.
v A heat-sink FRU can be ordered separately if the thermal material becomes
contaminated.
To remove a microprocessor, complete the following steps.
Heat Sink
Microprocessor
1. Read the safety information that begins on page vii, and “Installation guidelines”
on page 13.
2. If the blade workstation is installed in a BladeCenter unit, remove it (see
“Removing the blade workstation from a BladeCenter unit” on page 16 for
instructions).
3. Remove the blade workstation cover (see “Removing the blade workstation
cover” on page 19 for instructions).
4. Remove the bezel assembly (see “Removing the bezel assembly” on page 21
for instructions).
5. Identify the microprocessor that is to be removed.
6. 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 replace the heat
sink.
