| Summary: | Redundancy of data and/or inline power in a wired data telecommunications network from a pair of network devices via a selection device is provided by communicating redundant signals with each of the pair of network devices and coupling ports of the first network device and corresponding ports of the second network device to paired inputs of the selection device. The selection device operates: 1) under the control of the pair of network devices, one acting as master and one as slave, the master selecting (for each port or for all ports) one of the two paired inputs and causing the selection device to communicate data and/or inline power via a third port of the selection device to a third network device receiving data connectivity and/or inline power from the selection device; or 2) to route two redundant signals to a third network device which then selects one for use. |
