Abstract
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.
