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. Read "Safety information" on page 123 and "Installation guidelines" on page 39.
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 46);
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 electrostatic discharge-sensitive devices" on page 126.
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.
5. Rotate the locking lever on the microprocessor socket from its closed and
locked position until it stops or clicks in the fully open position (approximately
135° angle), as shown. Then, see the documentation provided with the
microprocessor option for complete installation instructions.
Attention:
You must ensure that the locking lever on the microprocessor
socket is in the fully open position before you insert the microprocessor in the
socket. Failure to do so might result in permanent damage to the
microprocessor, microprocessor socket, and system board.
