Abstract
A powered device (PD) for Power over Ethernet (PoE), a PoE system, and an operating method for PoE are provided. The powered device includes a first Ethernet transmission port, a second Ethernet transmission port, a power meter, and a controller. The first Ethernet transmission port receives a first power and a first packet from a power sourcing equipment (PSE). The first packet includes a first output voltage value and a first maximum allowable power value. The second Ethernet transmission port provides a second power to a next-level powered device. The power meter measures an input voltage value and an input current value of the powered device. The controller sends a second packet to the next-level powered device via the second Ethernet transmission port. The second packet includes a second output voltage value and a second maximum allowable power value.
