Special Considerations for the 4200 W AC and 6000 W AC Power Supplies

The 4200 W AC and 6000 W AC power supply has two inputs: each can be powered at 110 or 220 V.
The output of the show power command for the 4200 W AC and 6000 W AC power supplies are similar
to that of 1400 W DC triple-input power supply (that is, the status of the submodules (multiple inputs)
is displayed). With these two power supplies, you can distinguish submodule "failed" versus "off," and
the status of the submodules (good, bad, or off):
