Abstract

A powered device on a network is isolated by communicating operating power and data to a powered device from a network line, referencing the network line to a line reference, and referencing the powered device to a device reference that can be different from the line reference. The powered device is isolated from the network line with an isolation boundary positioned between distributed power and the powered device at a digital port coupled to the powered device.
