This publication could include technical inaccuracies or typographical errors. Changes are periodically made to the information herein; these changes will be incorporated in new editions of the publication. [. . . ] The microprocessor sockets in this server contain built-in termination for the microprocessor bus; therefore, terminator cards are not required for empty microprocessor sockets. However, each empty microprocessor socket contains a protective, flat plastic cover that you must remove before you install a microprocessor in these sockets. To ensure proper server operation, microprocessor socket 4 contains a plastic microprocessor baffle that resembles a heat sink. You must remove the microprocessor baffle when you install a microprocessor in socket 4. Otherwise, the microprocessor baffle must remain in place to ensure proper airflow in your server. If you need to install additional microprocessors and VRMs, install them in the order listed in Table 8. The corresponding VRM connector is located adjacent to the microprocessor socket. Important: If you do not install the microprocessors in the correct order, the server will not operate properly. Table 8.

Attention: When you handle static-sensitive devices, take precautions to avoid damage from static electricity. For details about handling these devices, see "Handling static-sensitive devices" on page 40. Review the information in "Before you begin" on page 39 and "Safety information" on page 167. Turn off the server and disconnect all power cords and external cables; then, remove the server cover (see "Removing the top cover and bezel" on page 49). 88 90 xSeries 255 Type 8685: Hardware Maintenance Manual and Troubleshooting Guide 3. Pull out the two plastic fasteners on the front of the air baffle. Note: Do not remove the fasteners from the air baffle.
