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 9000 W AC power supply has three inputs: each can be powered at 110 or 220V.
The output of the show power command for the 4200 W AC, 6000 W AC, and 9000W 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 power supplies, you can distinguish submodule “failed”
versus “off,” and the status of the submodules (good, bad, or off):

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 21.
4. Not available for PoE.
5. Not available for PoE.
6. No voice power.
7. Data-only.
8. Inline power.
