Abstract
An apparatus provides power to a device over a network transmission medium. The apparatus includes a controller which determines if the device can accept power over the network transmission medium, and which outputs a signal if the device can accept power over the network transmission medium. A circuit provides power to the device over the network transmission medium in response to the signal.
