Claim:
1. An apparatus comprising: a power distribution unit that distributes electric power to a network device, the power distribution unit comprising: a set of power supply modules electrically coupled to the power distribution unit, each power supply module within the set of power supply modules being capable of outputting electric power to the network device upon receiving current via either the first set of power inputs or the second set of power inputs; a movable mechanical cover that prevents the power distribution unit from simultaneously exposing: a system control circuit communicatively coupled to the set of power supply modules; a switch that mechanically interfaces with the movable mechanical cover and is communicatively coupled to the system control circuit, the switch providing, to the system control circuit, a signal that indicates whether the first set of power inputs or the second set of power inputs are exposed by the movable mechanical cover; and wherein the system control circuit uses the signal to determine an amount of current received by either the first set of power inputs or the second set of power inputs.
