Module power is the output from the power supply (internal to the system). The AC-input power is the
Note
input from the outlet to the power supply. The percentage difference between the two values is the
efficiency of the power supply.

The module power values are based on 42 VDC. Power is distributed to each slot in the chassis from the
Note
power supply's 42 VDC output. Each module has DC-to-DC power supplies that convert the 42 VDC
into +2.5 VDC, +3.3 VDC, and +5 VDC to power the module. The 42 VDC is independent of the power
supply's input voltage, either 110 VAC or 220 VAC.
