Abstract
In some implementations, a method is provided. The method may allow a powered device to determine the maximum power available from power supply equipment. The method includes determining the length of a cable connecting the powered device to the power supply equipment based on the resistance of the cable. The method further includes determining the maximum power available to the powered device based on the length of the cable. The powered device may then be operated based on the maximum power available.
