Abstract:
A system employing power over Ethernet (PoE) technology may include at least one powered device and power sourcing equipment (PSE). The powered device may include a first powered device (PD) subsystem and a second powered device (PD) subsystem that is electrically isolated from the first PD subsystem. The powered device may also include an interface connecting the first PD subsystem and the second PD subsystem. The PSE may be operable to provide power to one or more of the PD subsystems through a link connecting the PSE to the powered device. Also, the first PD subsystem may be operable to receive a communication from and transfer power to the second PD subsystem through the interface while maintaining the electrical isolation.
