grid. For example, if three power supply units are connected to a 110-V grid and a 220-V grid, each
power supply outputs 1.2 kW for the 110-V grid and 3.0 kW for the 220-V grid. The available power
would be 3.6 kW (1.2 kW + 1.2 kW + 1.2 kW) and the reserve power would be 9.0 kW (3.0 kW +
3.0 kW + 3.0 kW).
• Full redundancy mode—Provides both power-supply redundancy and input-source redundancy.
This mode allows you to replace a power supply unit without interrupting device operations or
continue powering the device 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.
The amount of power available for use with your Cisco Nexus 7000 Series device depends on the number
of power supply units, input voltage used, and the power mode used. To determine the amount of
available power for 6-kW power supply units, see
