The techniques described herein relate to methods and apparatus for a power over Ethernet (PoE) light for media applications. The PoE light includes a light, wherein the light requires a wattage of at least 30 watts for proper operation. The PoE light includes a processor configured to control the light. The PoE light includes a port in electrical communication with the processor, wherein the port is configured to receive an Ethernet cable that provides communication with a router, wherein the router provides over the Ethernet cable both: power for the PoE light to operate at the wattage, and data communications for the PoE light so that the processor can transmit and receive data communications according to DMX (Digital Multiplex) protocol so the light can be remotely controlled by a user.

A power sourcing device measures a resistance between the A pairs of an Ethernet cable to determine a first signature resistance value and uses the first signature resistance value to determine whether the device is able to receive power over the Ethernet cable in a manner compliant with the IEEE Power over Ethernet standard. In response to determining that the device can receive power over the Ethernet cable compliant with the standard, the power sourcing device provides power to the device over the Ethernet cable as specified by the standard. In response to determining that the device is not able to receive power over the Ethernet cable as specified by the standard, the power sourcing device uses the first signature resistance to determine a power request for the device and then provides a power signal over the Ethernet cable to the device that is consistent with the power request.

A power supply system includes a power supply device and a controller that is electrically connected to the power supply device. The controller is configured to allow the power supply device to detect whether a power-receiving device is electrically connected to the power supply device. The controller is further configured to, in response to determining that the power supply device is electrically connected to the power-receiving device, start to count a count value. The controller is further configured to, in response to determining that the count value is less than a threshold value, reset the count value, where the count value is for confirming whether the power-receiving device is still being electrically connected to the power supply device.

The present invention proposes a DC power distribution system comprising power source equipment (PSE) providing high powered power over ethernet connections of 200 W per ethernet cable connected with powered devices (PDs) and power distribution units (PDUs).
