Chapter 3 Technical Specifications
Power Specifications for the Nexus 7010 System
• Full redundancy mode—This mode provides both power-supply redundancy and input-source
redundancy. This mode lets you replace a power supply without interrupting system operations, and
it lets you continue powering the system if one of two grids goes down. The available power is
calculated as the lesser amount of output power for power supply redundancy or input source
redundancy.
Table 3-5 shows the amount of power that each power mode makes available for your Nexus 7000 system
depending on the hardware installed in your system, the amount of power input to the power supplies,
the voltage used for the input power, and the power mode you are using.
