iv BladeCenter S Types 7779 and 8886: Power Modules

Chapter 1. BladeCenter S chassis power modules
A minimum of two power modules must be installed in power module bays 1 and
2 on the rear of the BladeCenter S chassis. Additional power modules, if installed,
are installed in power module bays 3 and 4.

Power modules
The BladeCenter S system supports up to four autoranging power modules that
are capable of supporting either 110 V ac or 220 V ac.

AC power LED
DC power LED
Fault LED
There are two types of power modules. These power modules are identical except
for the power cord connector; one power module has a C14 connector and the
other power module has a C20 connector. Both types of power modules can be
installed in the same chassis.

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.
2BladeCenter S Types 7779 and 8886: Power Modules

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 disk storage
modules.
If you disengage or remove all devices from the front of the BladeCenter S chassis
(media tray, blade servers, and disk 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.
1. Verify that the power modules are properly connected to an AC power
source. All power modules in the BladeCenter S chassis must be
connected to the same power input voltage (either 110 V ac or 220 V
ac). Do not mix power input voltages.
2. Unplug the AC power cord from the power module and plug it in
again.
3. Reseat the power supply.
4. Swap the AC power cord with a power cord that is known to be
working.
5. Move the power module to another power module bay in the
BladeCenter S chassis.
