Attention: Do not set the heat sink down after you remove the plastic cover
and 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, contact your service
technician.

the server (directly above the microprocessor).
c. Remove the plastic cover from the bottom of the heat sink.
d. Align the heat sink, grease side down, with the microprocessor and
retention bracket.
e. Slide the rear flange of the heat sink into the opening beneath the
retention-bracket spring.
