Zusammenfassung:	A power sourcing equipment is provided. The power sourcing equipment may include an input terminal, an output terminal, a switch, and a device detection circuit. The input terminal may receive a power signal. The output terminal may be electrically coupled to a powered device via a coaxial cable, which transmits the power signal from the power sourcing equipment to the powered device or a data signal from the powered device to the power sourcing equipment. The switch may control an electrical connection between the input and output terminal(s). The device detection circuit may detect whether the data signal is being transmitted from the powered device to the power sourcing equipment. If the data signal is not being transmitted from the powered device to the power sourcing equipment, the device detection circuit may control an operation of the switch based on an electrical parameter associated with the powered device.
