- None - To reserve no power supplies.

- N+N - To reserve half of the power supplies.

Note - When you change the redundancy policy, this change affects the amount of power the CMM is permitted to allocate to server modules (blades). The chassis `Permitted` `Power` is set to the power that the available power supplies can provide minus the redundant power available. In addition, when there is no redundant power available to the system, a loss of a power supply will cause the system to reduce the `Permitted Power`. If the system reduces the `Permitted` `Power` below the power that had already been allocated, you should immediately take steps to turn off the server modules to reduce the allocated power.

- Redundant Power - This value is provided by the system. It represents the available power that is not allocated.
