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. Microprocessorlocking lever Microprocessor socket 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. 40 325 Type 8835: Hardware Maintenance Manual and Troubleshooting Guide Eserver

Attention:
To
avoid
damage
and
to
ensure
proper
server
operation,
review
the
following
information
before
you
install
a
microprocessor:
v
