Opening the cover Complete the following steps to open the server cover: 1. Read the safety information beginning on page v and "Installation guidelines" on page 7. Latch NOTE: FOR PROPER FRONT OF BOX AIRFLOW, NOTE: FOR PROPER AIRFLOW, FRONT OF BOX REPLACE FAN WITHIN 2 MINUTES REPLACE FAN WITHIN 2 MINUTES Figure 3. Opening the cover 2. Before opening the top cover, you must remove the rack-support wheels and handles from the server. See the Rack Installation Instructions for information. 3. Press the release latch on the left half of the top cover to the right. 4. Using the finger hole in the release latch, open the left half of the cover; then, open the right half of the cover. Attention: For proper cooling and airflow, close the cover before turning on the server. Operating the server for extended periods of time (more than 30 minutes) with the cover open might damage server components. The SMP Expansion Module The SMP Expansion Module contains the XceL4 system cache, DIMMs, microprocessors, and voltage regulator modules (VRMs). This section provides instructions for removing and installing the SMP Expansion Module, microprocessors, VRMs, and DIMMs. The following notes describe components in the SMP Expansion Module and other information that you must consider when installing an SMP Expansion Module: v Use two hands to install or remove an SMP Expansion Module. Do not allow the expansion module to come in contact with the center plane while lifting it out of or setting it into the server. v For your server to operate properly, there must be a minimum of one SMP Expansion Module installed. v An SMP Expansion Module must contain at least one microprocessor and two DIMMs. v If there is only one SMP Expansion Module installed in the server, an SMP baffle must be installed in place of the upper SMP Expansion Module to ensure proper cooling of the server.
