To configure the power settings for the chassis specifically for 'Combined Mode Resiliency', use the
power redundancy combined max inputs command. To return to the default setting, use the default
form of this command.
Note This feature only applies in combined mode when both power supply bays contain the 4200 W AC, 6000
W AC, or 9000W power supply.

Command History
Usage Guidelines Using the combined mode power resiliency feature, you can limit the power usage to a maximum of two
or three (configurable) inputs for 4000W and 6000W power supplies. For 9000W power supplies, you
can limit the power usage to a maximum of 2 to 5 inputs, since the 9000W is a triple input power supply.
With two 4200 W AC or 6000 W AC power supplies, a maximum of four inputs are available. With two
9000W, a maximum of six inputs are available. This feature allows you to cap the power usage to that of
two/three inputs or four/five inputs. If one of the power supplies fails, no loss of power occurs because
you have capped its usage to a smaller number of inputs.
If you have max inputs 3 configured with four "good" (220 V) inputs and you limit the user to 5500 W
instead of 7600 W and one subunit fails or is powered off, you have three quality inputs providing 5500
W and the chassis is powered at the same rate as it was prior to the failure event:

x | y Sets the max input limits.
If 9000W power supplies are installed, the valid input range is 2-5.
Note The maximum number of power-supply inputs with two 9000W power
supplies is 6.
If 4200W or 6000W power supplies are installed, the valid input range is 2-3.
Note The maximum number of power-supply inputs with either two 4200W or
two 6000W power supplies is 4.
