IBM System x3550 M5 Type 5463: Installation and Service Guide
1. Read the safety information that begins on "Safety" on page vii and
"Installation guidelines" on page 122.
2. Turn off the server and peripheral devices and disconnect all power cords.
3. Remove the cover (see "Removing the cover" on page 126).
4. Remove the air baffle (see "Removing the air baffle" on page 129).
5. Locate the microprocessor to be removed (see "System-board internal
connectors" on page 27).
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. Use a screwdriver to loosen the captive screw on one side of the heat sink
to break the seal with the microprocessor.
b. Loosen all the captive screws on the heat sink, rotating each screw one full
turn until each screw is loose.
c. Gently lift the heat sink from the microprocessor. After removal, place the
heat sink (with the thermal grease side up) on a clean, flat surface.
