Abstract
A system has a power consuming component, power source circuitry, and power control circuitry. The power source circuitry is to supply power from a number of different sources, including some extracted from a local area network (LAN) cable that is attached to the system. The power control circuitry is to supply the power to operate the component from all of the different sources.
