Attention:
1) Do not use excessive force when pressing the microprocessor into the
socket.
2) Make sure that the microprocessor is oriented and aligned correctly
with pin number 1 in the socket before you try to close the
microprocessor-release lever. The following illustration shows the
alignment marks for both microprocessors and sockets.

c. Center the microprocessor over the microprocessor socket. Align the
triangle on the corner of the microprocessor with the triangle on the corner
of the socket and carefully press the microprocessor into the socket.
d. Carefully close the microprocessor-release lever to secure the
microprocessor in the socket.
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 heat sink
becomes contaminated, it must be cleaned and replaced by a service
technician.

9. Install the heat sink on the microprocessor.
a. Make sure that the heat-sink-release lever is in the fully open position
(135°).
b. Orient the heat sink so that the thermal grease patch is nearer the rear of
the server (directly above the microprocessor); then, remove the protective
plastic cover from the bottom of the heat sink.
