1. A method comprising:
identifying at a first powered device in communication with power sourcing equipment, a second powered device in communication with the first powered device, wherein the first powered device is receiving pulse power from the power sourcing equipment;
notifying the power sourcing equipment of the second powered device at the first powered device; and
performing a power initialization at the first powered device with the second powered device before passing the pulse power to the second powered device,
wherein the power initialization is performed at a power level lower than the power level of the pulse power received from the power sourcing equipment.
