Complete the following steps to install an additional microprocessor: 1. Review the information in "Installation guidelines" on page 45, "Handling static-sensitive devices" on page 46, and "Safety information" on page 169. 2. Turn off the server and disconnect all power cords and external cables ("Turning off the server" on page 9); then, remove the server cover (see "Removing the server left-side cover and bezel (tower model)" on page 55 or "Removing the server top cover and bezel (rack configuration)" on page 57). 3. Open the cover on the air-baffle assembly. (See the illustration following step 3 on page 81, if needed.) Note: It is not necessary to remove the air-baffle assembly to perform this step. 4. Locate the second microprocessor socket (connector U27) on the system board. 5. Remove the microprocessor baffle from the microprocessor socket. 6. Remove the protective cover, tape or label from the surface of the microprocessor socket, if present. 84 xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide
