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):
Switch# show power

------ ---------------- --------- ----------- ------- -------
PS1 PWR-C45-4200ACV AC 4200W good good good
PS1-1 220V good
PS1-2 off
PS2 PWR-C45-4200ACV AC 4200W bad/off good bad/off
PS2-1 220V good
PS2-2 220V bad

As with other power supplies, the two power supplies must be of the same type (6000 W AC or 4200 W
AC or 1400 W DC). Otherwise, the right power supply is put in err-disable state and the left one is
selected. In addition, all the inputs to the chassis must be at the same voltage. In redundant mode, the
inputs to the left and right power supplies must be identical. If the left and right power supplies are
powered in redundant mode, the power values is based on the power supply with the higher output
wattage.

1. Chassis power includes power for the supervisor engine(s), all line cards, and the fan tray.
2. The efficiency for the 1400 W DC power supply is 0.75, and 0.96 is applied to PoE.
3. DC input can vary for the 1400 W DC power supply and is configurable. For more information, see “Special Considerations
for the 1400 W DC Power Supply” on page 18.
4. Not available for PoE.
5. Not available for PoE.
6. No voice power.
7. Data-only.
8. Inline power.
