Power Summary
(in Watts)
----------------------
System Power (12V)
Inline Power (-50V)
Backplane Power (3.3V)
----------------------
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.
When the system is powered with a 4200 W, 6000 W, or 9000W power supply either in 110 V or 220 V
Note
combined mode operation, the available power is determined by the configuration of the system (the type
of line cards, the number of line cards, number of ports consuming inline power, etc.) and does not reflect
the absolute maximum power.
In a matched redundant power supply configuration, if a power supply submodule fails, the other (good)

power supply provides power to its full capability.

In combined mode, all the inputs to the chassis must be at the same voltage.
