 #### power-chassis-good
 Indicates the power good state of the chassis.
 
+#### power-config-full-load
+Output GPIO set by the power managing application that indicates to the hardware
+the threshold of power supplies that are expected to be present and working for
+this type of system for the case where a system has a model that supports two
+different number of power supplies (example 2 or 4). Default is the lowest
+number of power supplies expected of the two models. In the case when the number
+of power supplies that are present are less than the ones indicated by this
+GPIO, the hardware can then take actions such as reducing the system's
+performance so that it can maintain its powered on state.

 #### regulator-standby-faulted
 This GPIO value represents the status of standby power regulator fault detection
-logic. This GPIO is an input only. The status will reflect a regulator 
+logic. This GPIO is an input only. The status will reflect a regulator
 non-faulted condition after AC power cycle when no standby power regulator fault
 condition is present. The status will reflect a standby regulator power faulted
 condition when an unexpected drop in standby power is detected.
