To remove a microprocessor and heat sink, complete the following steps:
Procedure
1. Read the safety information that begins on "Safety" on page vii and
"Installation guidelines" on page 33.
2. Turn off the server and peripheral devices and disconnect all power cords.
3. Remove the cover (see "Removing the cover" on page 36).
4. Remove the air baffle (see "Removing the air baffle" on page 37).
5. Locate the microprocessor to be removed (see "System-board internal
connectors" on page 28).
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 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 retention module release lever to the fully open
position.
b. Lift the heat sink out of the server. After removal, place the heat sink (with
the thermal grease side up) on a clean, flat surface.
