Power and data redundancy in a single wiring closet |
摘要 |
Redundancy of data and/or Inline Power in a wired data telecommunications network from a first network device and a second network device configured as power sourcing equipment (PSE) devices and coupled together and to a third network device (such as a PD) via a Y device is provided by providing redundant signaling to/from each of the pair of network devices, and coupling a port of each of the network devices to the Y device and from there to a third port where a third network device such as a PD may be coupled. Because the Y device is essentially passive, communications paths between the PSE devices and the PD are provided for negotiating master/slave status and other status and related information among the respective network devices. Dynamic impedance matching is provided to handle situations where not all devices are plugged in and as a communications technique among the devices.
