Abstract
A method for rapidly powering a plurality of power over Ethernet ports constituted of: inputting an indication of available power; allocating a power budget to each of a first plurality of power over Ethernet devices; transmitting an enabling command for ports of a first priority to the first plurality of power over Ethernet devices, each of the first plurality of power over Ethernet devices powering ports of the first priority within the power budget; monitoring an indication of power consumption until the power consumption has stabilized; allocating an updated power budget to each of the first plurality of power over Ethernet devices, the power budget being a function of the available power and at least one of an indication of power consumption and power allocation; and transmitting an enabling command for ports of a second lower priority to the first plurality of power over Ethernet devices.
