The Power Supply Concept
The system comes with two hot-swappable power supply units in a redundant
power supply configuration. They automatically adjust to any power voltage in
the range (100 V - 127V or 200 V - 240 V) and ensure the power supply for the
system. If one of these units fails, the second one ensures that operation
continues unimpaired. The defective power supply unit can be replaced during
operation (hot-swap).

Power Supply Unit (PSU)
The power supply units are directly accessible at the rear of the system
(figure 75):

The power supply unit can communicate with the system service processor via
the I2C bus interface. PSU part number, FRU number, barcode number,
manufacturer ID, and fault data are stored in a VPD EEPROM module with an
I2C interface. The PSU status can be displayed in the server management
software
