Installing a microprocessor Complete the following steps to install a microprocessor. Attention: When you handle static-sensitive devices, take precautions to avoid damage from static electricity. For details on handling these devices, see "Handling static-sensitive devices" on page 27. 1. Review the safety precautions listed in Statement 1 and Statement 5 in "Safety information" on page 28. 2. Turn off the server and peripheral devices and disconnect all external cables and power cords; then, remove the cover (see "Removing the side cover" on page 33 for details). 3. Remove the support-bracket assembly and disconnect the fan cable from the connector (SYSFA3) on the system board. See "Removing the support-bracket assembly" on page 34 and "System board internal cable connectors" on page 24 for instructions. 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. Pull out and lift up on the microprocessor-release lever to unlock the microprocessor connector. c. Arrange the microprocessor over the microprocessor connector as shown in the following illustration. Carefully press the microprocessor into the connector.

Push the microprocessor-release lever down to lock the microprocessor into the connector. 6. Install the new heat or fan sink that comes with the microprocessor option. a. Peel the plastic protective strip off the bottom of the heat or the fan sink. Make sure the square of thermal material is still on the bottom of the heat sink or fan sink; if not, replace the it with a new heat sink or fan sink. b. Align and place the heat sink or the fan sink on top of the microprocessor. c. Locate the tab on the front of the microprocessor socket (the side facing the PCI slots). Then, press down and latch the retainer onto the tab. 48 IBM xSeries 200: User's Reference
