IBM 8676 - Eserver xSeries 335 Installation Manual page 31

Attention: To avoid damage and to ensure proper server operation, review the
following information before you install a microprocessor:
v Ensure that the microprocessors are the same type, have the same cache size,
and have the same clock speed.
v Ensure that the microprocessor internal and external clock frequencies are
identical.
v See the ServerProven list at http://www.ibm.com/pc/compat/ for a list of
microprocessors supported by the server.
A new microprocessor comes in a kit with a VRM and a heat sink.
Complete the following steps to install a microprocessor:
1. Review the safety information beginning on page v, and "Installation guidelines"
on page 7.
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 cover (see "Removing the cover and bezel" on page 8);
then, determine the socket where the microprocessor is to be installed.
Attention:
v Avoid touching the components and gold-edge connectors on the
microprocessor. Ensure 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 7.
Note: A new microprocessor comes in a kit with a VRM and a heat sink.
4. If you are installing a microprocessor in the microprocessor 2 socket, first install
a VRM in the microprocessor 2 VRM slot (J42) and remove the protective cover
from the microprocessor 2 socket; then, lift the microprocessor-release lever to
the open position.

Note: The microprocessor-release lever is on the side of the socket that faces
the rear of the server.
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.
