Chapter 10 Environmental Monitoring and Power Management Power Management
Note When the system is powered with a 4200 W or 6000 W power supply either in 110 V or 220 V 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.
Note In a matched redundant power supply configuration, if a power supply submodule fails, the other (good)
power supply provides power to its full capability.
Table 10-7 illustrates how the 4200 W AC power supply is evaluated in redundant mode.
In combined mode, all the inputs to the chassis must be at the same voltage.
Table 10-8 illustrates how the 4200 W AC power supply is evaluated in combined mode.
Table 10-9 illustrates how the 6000 W AC power supply is evaluated in redundant mode.
