Abstract
An improved method is performed within power-sourcing equipment. The method controls delivery of power to a remotely powerable device through a communications pathway that connects the power-sourcing equipment to the remotely powerable device. The method involves obtaining an initial resistance value representing an initial resistance of the communications pathway, and obtaining an operating resistance value representing an operating resistance of the communications pathway after obtaining the initial resistance value. The method further involves generating a temperature change result based on the initial resistance value and the operating resistance value, and selectively one of enabling, scaling back and disabling delivery of power to the remotely powerable device through the communications pathway based on the temperature change result.
