Note: The following illustration shows how to install an MPE unit on the blade server; installing another type of expansion unit on a blade server is similar. Extraction thumbscrew Expansion unit Blade-cover release Blade expansion connector cover Blade-cover release MPE unit connector cover Note: The MPE unit must be installed on a blade server and should not be installed on another expansion device. To install the MPE unit or an expansion unit, complete the following steps: 1. Read the safety information that begins on page v and "Installation guidelines" on page 17. 2. If the blade server cover is installed, remove it now (see "Opening the blade server cover" on page 20 for instructions). 3. If you removed the blade bezel assembly, install it now (see "Installing the bezel assembly" on page 37 for instructions). 4. If the blade expansion connector cover on your blade server is installed, remove it by pulling the cover off of the connector. 5. If you are installing an MPE unit and the MPE connector cover on your blade server is installed, remove it by pulling the cover off of the connector. 6. If you are installing a new expansion unit, touch the static-protective package that contains the expansion unit to any unpainted metal surface on the BladeCenter unit or any unpainted metal surface on any other grounded rack component; then, remove the expansion unit from the package. 7. Orient the expansion unit above the blade server. 8. Lower the expansion unit so that the slots at the rear slide down onto the cover pins at the rear of the blade server. 9. Pivot the expansion unit closed. The connectors on the expansion unit automatically align with and connect to the connectors on the blade server system board. 10. If the expansion unit has an extraction device (such as a thumbscrew or a lever), use it to fully engage the expansion unit on the blade server; otherwise, press the expansion unit firmly into the closed position until it clicks into place. 38 BladeCenter LS21 Type 7971 and LS41 Type 7972: Installation and User's Guide
