2.2 600-W 1+1 Power Supply Module
The 600-W power supply module specification defines a 1+1 power supply module that
supports pedestal server systems. It defines a 600-W power supply with 2 outputs: +12Vdc and
+5Vsb. A separate cage (including power distribution board) is designed to plug directly to the
output connector of the PS module and provide additional power converters to produce other
required voltages. An IEC connector is provided on the external face for AC input to the power
supply. The power supply contains cooling fans, while meeting acoustic requirements.
