Abstract
A method for monitoring power delivered to a powered device over communication cabling, the method comprising: enabling a first supply power; enabling a second supply power; for the enabled first supply power, providing a first maintain power signature (MPS) functionality arranged to disable the enabled first supply power in the event that the current drawn from the enabled first supply power is less than the first undercurrent threshold; for the enabled second supply power, providing a second maintain power signature (MPS) functionality arranged to disable the enabled second supply power in the event that the current drawn from the enabled second supply power is less than the second undercurrent threshold; receiving an indication that the powered device presents a single powered device interface to both the first and the second PSE; and controlling one of the provided first and second MPS functionality responsive to the received indication.
