Power source requirements
The BladeCenter S system can run on either 110 V ac or 220 V ac. Each of the four
power supplies in the BladeCenter S chassis is capable of handling either type of
power source.
Note:
Although the power modules are autoranging and can support either 110 V
ac or 220 V ac, you cannot mix voltage power sources within the same BladeCenter
S system. All power modules within a BladeCenter S system must be connected to
either a 110 V ac or 220 V ac power sources.
AC power input must be adequate to supply the required voltage and amperage at
an input frequency range from 50-60 hertz (Hz). The BladeCenter S system requires
the following ac input voltage:

Power consumption guidelines
The BladeCenter S system is configurable with varying numbers of some
individual components. As you add components to the BladeCenter S system, the
power consumption increases.
Blade servers, fan modules, SAS or SATA drives, and other components all
contribute to the power footprint. A BladeCenter S system can have a minimum of
two or a maximum of four power supply modules that must provide the 12-volt
power for all of the components that you are including in the chassis.
