Abstract
A method, apparatus, and computer usable program product for providing power over Ethernet are provided in the illustrative embodiments. The apparatus and method for providing power over Ethernet includes a first device that receives power from a computer. A second device may be in communication with the first device using a wired section of the Ethernet. The first device provides electrical power to operate the second device using the wired section of the Ethernet. One method for providing power over a data network may include determining availability of a power injector. A determination may be made whether a connected device is capable of receiving power over Ethernet. If the connected device is capable of receiving power over the Ethernet, electrical power may be provided from the power injector to the connected device.
