Power Supply Configuration Modes
•
Full redundancy mode—Provides both power-supply redundancy and input-source redundancy.
This mode lets you replace a power supply without interrupting system operations or continue
powering the switch if one of two grids goes down. The available power is the lesser amount of
output power for power supply redundancy or input source redundancy.
To determine the amount of available power for 6-kW power supply units in each power mode, see
. To determine the amount of available power for 7.5-kW power supply units, see
