Power Distribution when a Power Supply Is Removed or Added

When a power supply is removed, the SSA responds to the decrease in available power by doing the following:

1. Detecting the power supply removal and recalculating available power.
2. Subtracting the power capacity for its base system from available power.
3. Distributing remaining power equally for PoE.
4. Dropping support to PoE devices as necessary to stay within the programmed maximum power.

When a power supply is added, the SSA responds to the increase in available power by doing the following:

1. Detecting the power supply addition and recalculating available power.
2. Subtracting the power capacity for its base system from available power.
3. Distributing remaining power equally for PoE.
