Power Supply Units | Power Supply Concept |
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.
14.1Power Supply Units
The power supply units (PSU) are directly accessible at the rear of the system (figure 88 on page 139):
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 figure 89 below).
