Attention: To avoid damage and to ensure proper server operation, review the
following information before you install a microprocessor:
v Make sure that the microprocessors are the same type, have the same cache
size, and have the same clock speed.
v
See the ServerProven list at http://www.ibm.com/pc/us/compat/ for a list of
microprocessors that are supported by the server.
The following procedure describes installation of a microprocessor. Microprocessors
should be removed only by qualified service technicians (see “Removing a
microprocessor” on page 54).
Complete the following steps to install a microprocessor:
1. Read “Safety information” on page 101 and “Installation guidelines” on page 25.
2. Turn off the server and all attached peripheral devices. Disconnect all power
cords; then, disconnect all external signal cables from the server.
3. Remove the server from the rack; then, remove the server cover (see
“Removing the cover and bezel” on page 27). Determine the socket where the
microprocessor is to be installed.
Attention:
v Avoid touching the components and gold-edge connectors on the
microprocessor. Make sure that the microprocessor is completely and
correctly seated in the socket. Incomplete insertion might cause damage to
the system board or to the microprocessor.
v
When you handle static-sensitive devices, take precautions to avoid damage
from static electricity. For information about handling these devices, see
“Handling static-sensitive devices” on page 25.
Note: A new microprocessor comes in a kit with a heat sink.
4. If you are installing a microprocessor in the microprocessor 2 socket, lift the
microprocessor-locking lever to the open position.

5. Install the microprocessor:
a. Touch the static-protective package containing the new microprocessor to
any unpainted metal surface on the server; then, remove the microprocessor
from the package.
b. Position the microprocessor over the microprocessor socket as shown in the
following illustration. Carefully press the microprocessor into the socket.
Attention: To avoid bending the pins on the microprocessor, do not use
excessive force when pressing it into the socket.
