b. Turn the VRM so that the keys align correctly with the VRM connector.
c. Firmly press the VRM straight down into the connector by applying
pressure on both ends of the VRM simultaneously.
d. Make sure that the retaining clips are in the locked position when the VRM
is firmly seated in the connector.
2. Touch the static-protective package containing the microprocessor to any
unpainted metal surface on the server. Then, remove the microprocessor from
the package.
3. Remove the protective dust cover, tape, or label from the surface of the
microprocessor socket, if present.
4. Rotate the microprocessor release lever on the socket from its closed and
locked position until it stops in the fully open position.
Attention:
v Use the vacuum tool that comes with the microprocessor to install the
microprocessor. Dropping the microprocessor during installation or removal
can damage the contacts. Also, contaminants on the microprocessor
contacts, such as oil from your skin, can cause connection failures between
the contacts and the socket.
v Do not use excessive force when you press the microprocessor into the
socket.
v Make sure that the microprocessor is oriented and aligned and positioned in
the socket before you try to close the lever.

5. Align the microprocessor with the socket (note the alignment mark and the
position of the notches); then, using the vacuum tool, carefully place the
microprocessor on the socket. Close the microprocessor bracket frame.
Note: The microprocessor fits only one way on the socket.
6. Carefully close the microprocessor release lever to secure the microprocessor
in the socket.
7. Install a heat sink on the microprocessor.
