The power supply system consists of one power supply module and a backplane providing the removable function of the power supply module, or the power supply system consists of one or two power supply modules and a backplane providing the removable or redundancy function of the power supply module. The DC Input is rated –45V to –60V. There are five outputs: +12V/60.0A, +5V/30.0A, +3.3V/30.0A, -12V/0.5A, and+5VSB/3.0A. A 38mm high reliable fan is applied to the power supply module for cooling the power supply module and part of the system.
