Abstract
Power feed circuitry within a power over Ethernet (PoE) device detects fault conditions within power and data distribution lines coupled to the power feed circuitry. This circuitry includes network interface circuitry coupled to the network in order to exchange both data and power signals. The power interface circuitry also communicatively couples to at least one isolated power supply in order to draw power. The power may then be distributed via the attached network interface circuitry. A fault detection module couples to the power interface circuitry and the network interface circuitry. This fault detection module senses fault conditions associated with the power interface circuitry, network interface circuitry, and associated distribution lines in order to better draw and distribute power signals using the power feed circuitry.
