Installing an optional expansion unit
Use these instructions to install an optional expansion unit.
Attention: If a horizontal combination-form-factor (CFFh) expansion card is
installed on the blade server system board, you cannot install an optional
expansion unit.
Notes:
1. All devices should be installed in an expansion unit before attaching it to the
blade server.
2.
After you install one or more expansion units on your blade server, the
combined blade server and expansion units together occupy adjacent blade
bays in the BladeCenter unit. Enough power modules must be installed in the
BladeCenter unit to power the blade bays in which you install the blade server
and expansion units.
3. The following illustration shows an optional expansion unit in a blade server.
4. The illustrations in this document might differ slightly from your hardware.
To install an optional expansion unit, complete the following steps.
Blade server

Expansion unit
Blade server
cover release
1.
Locate the blade expansion connector on the blade server system board or the
expansion unit and remove the cover if one is installed (see “Blade server
connectors” on page 15).
2. Touch the static-protective package that contains the optional 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 optional
expansion unit from the package.
3. Orient the optional expansion unit as shown in the illustration.
4. 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.
5. 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.
To install an optional GPU adapter into a GPU expansion unit, see “Installing a
GPU adapter in the BladeCenter GPU expansion unit” on page 88. To install an
option into another type of expansion unit, refer to the documentation
provided with the expansion unit.
