Separate power cords for AC redundancy
The power supplies are populated in the chassis in a specific order as viewed from the rear of
the server system. See Figure 9. For a rack configuration, the power supplies are installed from
left to right. In a pedestal configuration the modules are installed from the bottom to the top. All
of the power supplies implement blind mating connectors for easy installation. Each power
supply implements two AC input fuses rated at 250V/15A, one for line and one neutral. Power
supplies are not required to be on the same AC power phase. The power supply is held to the
chassis frame with four 6-32 screws. These four screws and the AC cord must be removed to
hot swap the power supply.

The power supply has four externally enabled outputs: +12V,+5V,+3.3V,-12V, and one +5VSB
(standby) output. The +5VSB standby output is present whenever AC power is applied to any
single power supply. The power supply has a minimum efficiency of 60% to its DC output pins at
maximum load currents at rated nominal input voltages and frequencies.
Several LEDs on each power supply can be viewed from the rear of the server system. These
indicate the power state for that particular module. Looking at the system from rear of the power
supply, from left to right the LEDs are power, predictive fail, and fail.
