Within the BladeCenter S chassis, all power supplies are combined into a single
power domain, which distributes power to each of the blade servers and modules
through the system midplane.
You must install a minimum of two power modules. If you install only two power
modules, install them in power module bays 1 and 2 (the top and bottom power
module bays on the right as you face the rear of the BladeCenter S chassis).
Note:
You must install all four power modules if you are using both storage
modules.
If you disengage or remove all devices from the front of the BladeCenter S chassis
(media tray, blade servers, and storage modules), the power modules will be
disabled.
Indicators and controls
There are three LEDs on each power module:
AC power
Lit (green). Power is being supplied to the power module.
DC power
Lit (green). Power is being supplied from the power module to the
BladeCenter S chassis midplane.
Fault
Lit (amber). There is a fault with the power module.
Note:
Before unplugging the AC power cord from the power module or
removing the power module from the BladeCenter S chassis, verify that the
capacity of the remaining power modules are sufficient to meet the
minimum power requirements for all components in the BladeCenter S
chassis. You can view power status and requirements through the
advanced management module.
For information on accessing and using the advanced management
module, see the
Advanced Management Module User's Guide
