Phase redundancy is possible in regions, where a single phase provides 
200 - 240V; in other regions with lower single phase voltage, two phases 
must be coupled and complete phase redundancy thus is not possible.
The unoccupied PSU slots are fitted with dummy modules to ensure that the 
electromagnetic emission properties of the system are observed and that the 
system components are properly cooled.

Power Supply Units
The power supply units (PSU) are directly accessible at the rear of the system 
(
):
The power supply unit can communicate with the system service processor via 
an internal management interface (IIC bus). The PSU part number, FRU data, 
barcode number, manufacturer ID, and fault data are stored in a VPD EEPROM 
module and can be recalled via the IIC bus. The PSU status can be displayed 
in the server management software 
ServerView
.
Each power supply unit has a large fan on the front (A) and two smaller fans on 
the rear (B) that provide air cooling for the system (see 
 below).
