Abstract

A Power-over-Ethernet (PoE) device (200) for use in a PoE system is described. The PoE device (200) comprising a first PoE port (210) for connecting the device to an upstream PoE device or a central control unit, a second PoE port (220) for connecting the device to a downstream device or PoE device and a control unit (240) for controlling data (335) and/or power communication (400) between the first (210) and second (220) PoE port. The control unit (240) further comprises a first power input terminal (305) connected to the first PoE port (210) to receive electrical power (320) for powering the control unit (240).
