1. Read the safety information that begins on page v and “Installation guidelines”
on page 23.
2. Turn off the server and peripheral devices and disconnect the power cords and
all external cables, if necessary (see “Turning off the server” on page 15).
Remove the server cover.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling these devices,
see “Handling static-sensitive devices” on page 25.
3. Locate microprocessor socket 2 on the system board.
4. Remove the microprocessor dust cover from the surface of the microprocessor
socket.

a. Press down and out on the release lever on the microprocessor socket. Lift
up the release lever until it stops in the fully open position (approximately
135° angle) and the top edge of the release lever has moved away from
the microprocessor socket.
b. Lift the hinged microprocessor bracket frame into an open position.
Remove the microprocessor dust cover from the bracket frame. Store the
dust cover in a safe place.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling these devices,
see “Handling static-sensitive devices” on page 25.
5. Touch the static-protective package that contains the new microprocessor to
any unpainted metal surface on the server; then, remove the microprocessor
from the package.
Attention: 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.
6. Position the microprocessor over the microprocessor socket. Use the triangular
alignment cutout on the microprocessor socket and the triangular alignment
mark on the microprocessor to assist you in aligning the microprocessor to the
socket. Then, carefully place the microprocessor into the socket. Do not force
the microprocessor, it only fits one way onto the socket.
