1. A method comprising:
receiving first pulse power from power sourcing equipment at a powered device;
synchronizing the powered device with a waveform of the first pulse power received from the power sourcing equipment; and
operating the powered device with second pulse power received from the power sourcing equipment,
wherein the first pulse power is at a power level lower than a power level of the second pulse power, and
wherein receiving the first pulse power and synchronizing are performed for each phase of a multi-phase pulse power system.
