ABSTRACT:
A method of controlling a power over Ethernet system, the method comprising: sequentially powering a plurality of powered devices over communication cabling; determining a first total power consumption responsive to the powering of the plurality of powered devices; in the event that the determined first total power consumption exceeds a predetermined maximum power level, disabling power from at least one of the powered plurality of powered devices thereby reducing power consumption to less than the predetermined maximum power level; responsive to the disabling power, defining a connection power limit lower than the maximum power level by a guard band; monitoring a second total power consumption subsequent to the disabling power; and enabling power to a powered device only in the event the monitored second total power consumption is less than the connection power limit.
