Abstract
A method and apparatus for redundant power and data over a wired data telecommunications network permits power to be received at a local powered device (PD) from remote power sourcing equipment (PSE) via at least one conductor at a first time and power and/or data to be obtained by the local device from another port of the remote device or another remote device at a second different time. Power levels obtained may be adjusted from time to time in response to circumstances.
