Abstract: In one embodiment, an apparatus comprises an input power interface for receiving input power, a power control system for transmitting DC (Direct Current) pulse power on multiple phases over a cable to a plurality of powered devices and verifying cable operation during an off-time of pulses in the DC pulse power, and a cable interface for delivery of the DC pulse power on the multiple phases and data over the cable to the powered devices. A method for transmitting multiple phase pulse power is also disclosed herein.
