1. Review the safety precautions in Statement 1 and Statement 5 in "Important
safety information" on page v and "Handling static-sensitive devices" on
page 42.
2. Turn off the server and peripheral devices and disconnect all external cables
and power cords; then remove the cover (see "Removing the left-side cover
(tower model)" on page 43 for details).
3. Remove the terminator card from the microprocessor connector. Store the
terminator card in a safe place in the static-protective package that your new
microprocessor comes in; you will need to install it again, if you ever remove
the microprocessor and do not replace it.
4. 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. Line up the microprocessor pins over the microprocessor connector and
carefully press the microprocessor into the connector.
c. Press down and latch the release lever.
Note: To remove a microprocessor, pull upward on the microprocessor release
lever and then lift the microprocessor off of the connector.
5. Install the voltage regulator module (VRM) included in the microprocessor kit.
Attention: When installing or replacing a VRM, use only a VRM specified
for use with the xSeries 232 server. Use of other VRMs might cause your
server to overheat.
a. Center the VRM over the VRM connector. Make sure that the VRM is
oriented and aligned correctly.
Note: The VRM is keyed to be installed only one way.
b. Press the VRM into the connector.
