Cisco Nexus 7000 Series Power Supply Redundancy
The Cisco Nexus 7000 Series Chassis supports multiple load-sharing, fault-tolerant, and hot-
swappable power supplies. As few as just one power supply can be used to operate a chassis.
Using multiple power supplies provides additional power capacity and resilience after failure of the
power supply, the generating supply itself, or a facility component such as a Uninterruptible Power
Supply (UPS) or a circuit breaker.
Cisco Nexus 7000 Series systems can operate in four user-configurable power-redundancy
modes, summarized in Table 3, to meet the redundancy needs of the environment.

Power Redundancy Modes
Redundancy Mode
Description
Combined
No redundancy; power available to the system is the sum of power outputs of all power
supplies in the chassis
supplies in the chassis
Power supply redundancy
(N+1)
(N+1)
Guards against failure of one of the power supplies; power available to the system is the
sum of the two least-rated power supplies
sum of the two least-rated power supplies
Input source redundancy
(grid redundancy)
(grid redundancy)
Guards against failure of one input circuit (grid); for grid redundancy, each input on the
power supply is connected to an independent AC feed, and power available to the system is
the minimum power from either of the input sources (grids)

redundancy
The total amount of power available to the Cisco Nexus 7000 Series system depends on the types
of power supplies installed, the number of connected inputs, and the configured power supply
redundancy mode. Table 4 shows the maximum available power for each redundancy mode for
the 6.0kW and 7.5kW power supplies.
