Statement 21
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.
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.
