The module power values are based on 42 VDC. Power is distributed to each slot in the chassis from the
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.
