Power Supply Configuration Modes

You can configure one of the following power modes to either use the combined power provided by the
installed power supplies or to provide power redundancy when there is a power loss:
•
•
•
OL-23069-07
Combined mode—Provides the maximum amount of available power by utilizing the combined
power output from all installed power supplies for switch operations. This mode does not provide
redundancy.
Power-supply redundancy mode—Allows you to replace a power supply during switch operations.
All power supplies are active. The available power is calculated as the least amount of power
available from all but one of the power supplies (N+1). The reserve power is the amount of power
output by the power supply that can output the most power. For example, if three power supplies
output 3 kW, 6 kW, and 6 kW, the available power is 9 kW (3 kW + 6 kW) and the reserve power is
6 kW.
Input source redundancy mode—Takes power from two electrical grids so that if one grid goes
down, the other grid can provide the power needed by the switch. For the Cisco Nexus 7004 chassis,
each grid powers half of the power supplies. For the Cisco Nexus 7009, 7010, and 7018 chassis, each
