Abstract: A powered communication device (31) comprises: a configurable resistor unit (35) coupled to the LAN port and adapted to generate a classification signal designating a power class of the powered communication device to be detected by the LAN switch, and a power module comprising a power converter (38) adapted to supply power to the electronic control unit (40) and to the peripherals in response to receiving power from the LAN port, wherein the electronic control unit (40) is configured to determine a power requirement of the communication device, detect a current resistance state of the configurable resistor unit (35) and, in response to detecting that the power requirement overshoots a power class associated to the current resistance state of the configurable resistor unit: reconfigure the configurable resistor unit (35) to designate a higher power class and, actuate the power switch (37) to transitorily put the LAN port (33) in a low-current state to be detected by the LAN switch.
