    摘要： A connector module includes a jack socket capable of receiving a communication link. The connector module also includes magnetics coupled to the jack socket for supplying power to a peripheral device coupled to the link through the jack socket. The connector module further includes Power-over-Ethernet management logic for controlling the supplying of power to the peripheral device by providing a voltage to the magnetics. In addition, the connector module includes at least one voltage isolator for isolating the voltage used by the Power-over-Ethernet management logic from at least one digitally-referenced voltage.
