Table 12-8 illustrates how the 6000 W AC power supply is evaluated in redundant mode.
In combined mode, all the inputs to the chassis must be at the same voltage.
Table 12-9 illustrates how the 6000 W AC power supply is evaluated in combined mode.
Combined Mode Power Resiliency
Note This feature only applies in combined mode when both power supply bays contain the 4200 W AC or
6000 W AC power supply.
Using the combined mode power resiliency feature, you can limit the power usage to a maximum of two
or three (configurable) inputs.
With two 4200 W AC or 6000 W AC power supplies, a maximum of four inputs are available. This
feature allows you to cap the power usage to that of two or three 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.
To configure the combined mode resiliency feature, perform this task:
220 V+220 V, other side 220 V 2200 40 4700 5500
Both sides at 220 V+220 V 2200 40 6200 7600
