Installing an expansion unit
Attention: If a high-speed expansion card is installed in the blade server system
board, you cannot install an expansion unit.
To install an expansion unit, complete the following steps.
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.

1. Remove the cover from the blade expansion connector, if one is installed.
2. If you are installing an MPE unit, remove the cover from the MPE unit
connector, if one is installed.
3. 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.
4. Orient the expansion unit above the blade server.
5. Lower the expansion unit so that the slots at the rear slide down onto the cover
pins at the rear of the blade server; then, pivot the expansion unit down onto
the blade server.
6. 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.
7. Install the blade-server cover, if required (see“Installing the blade server cover”
on page 69).
8. Install the blade server into the BladeCenter unit (see “Installing the blade
server in a BladeCenter unit” on page 66).
