Removing An Expansion Unit - IBM LS42 - BladeCenter - 7902 Service Manual

CAUTION:
Hazardous energy is present when the blade server is connected to the power
source. Always replace the blade cover before installing the blade server.
Attention: You cannot insert the blade server into the BladeCenter unit until the
cover is installed and closed. Do not attempt to override this protection.
To install the blade server cover, complete the following steps.
1. Read the safety information that begins on page "Safety statements" on page
viii and "Installation guidelines" on page 25.
2. If you removed the bezel assembly, install it (see "Installing the bezel
assembly" on page 34 for instructions).
3. If you removed an expansion unit from a double-width type blade server,
install it (see "Installing an expansion unit" on page 32 for instructions).
4. Lower the cover so that the slots at the rear slide down onto the pins at the
rear of the blade server. Before closing the cover, check that all components are
installed and seated correctly and that you have not left loose tools or parts
inside the blade server.
5. Pivot the cover to the closed position, as shown in the illustration, until it clicks
into place.
Note: Do not allow the control-panel cable to become caught between the
cover and the bezel assembly or air baffle.
6. Install the blade server into the BladeCenter unit (see "Installing the blade
server in a BladeCenter unit" on page 28).
