2. Turn off the server and peripheral devices and disconnect all external cables and power cords; then remove the cover (see "Removing the cover, door, and bezel" on page 48 for details). 3. Remove the air-baffle assembly from the fan assembly located on the rear of the server. Air baffle Insert 4. Remove the air-baffle insert from the air baffle assembly to accommodate the additional microprocessor. Store the air-baffle insert in a safe place for future use. Attention: If the server uses only one microprocessor, the air-baffle insert must remain clipped onto the air baffle assembly to ensure proper airflow over the microprocessor. 5. Pull out and lift up the release lever and remove the terminator card from the microprocessor connector. Store the terminator card in a safe place, such as 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. 6. 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. Note: Use the orientation indicator located on the microprocessor to properly align the microprocessor over the microprocessor connector, if available. 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 the connector. 7. 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. b. Press the VRM into the connector. Note: If you remove the microprocessor later, remember to install the terminator card in the appropriate microprocessor connector and remove the VRM. 70 Hardware Maintenance Manual: xSeries 232, Type 8668
