might result in permanent damage to the system board.
Important: 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.
1. Before you begin, read "Safety" on page v and "Installation guidelines" on
page 47.
2. If the blade server is installed in a BladeCenter unit, remove it (see
"Removing the blade server from the BladeCenter unit" on page 49 for
instructions).
3. Remove the blade server cover (see "Removing the blade server cover" on
page 52 for instructions).
4. If an optional expansion unit is installed, remove the expansion unit (see
"Removing an optional expansion unit" on page 79).
5. Locate the microprocessor that will be removed (see "Blade server connectors"
on page 13).
6. Remove the heat sink.
Attention: Do not touch the thermal grease on the bottom of the heat sink.
Touching the thermal grease will contaminate it. If the thermal grease on the
microprocessor or heat sink becomes contaminated, wipe off the contaminated
thermal grease on the microprocessor or heat sink with the alcohol wipes and
reapply clean thermal grease to the heat sink.
a. Loosen the screw on one side of the heat sink to break the seal with the
microprocessor.
b. Use a screwdriver to loosen the screws on the heat sink, rotating each
screw two full turns until each screw is loose.
c. Use your fingers to gently pull the heat sink from the microprocessor.
