Summary:Redundancy of data and/or Inline Power in a wired data telecommunications network from a pair of power sourcing equipment (PSE) devices via an automatic selection device is provided by providing redundant signaling to/from each of the pair of PSE devices, and coupling a port of one PSE device and a redundant port of the second PSE device to respective first and second interfaces of a port of the selection device. The selection device initially selects one of the two PSE devices and communicates data and/or Inline Power to a third interface of the selection device. A powered device (PD) coupled to that third interface communicates data and/or Inline Power with the selected one of the first and second PSE device through the selection device. Upon detection of a condition, such as a failure condition, the selection device may select the other of the two interfaces.
