Patent Images
1. A method of providing redundant power over a wired data telecommunications network, the method comprising:
- configuring a first device having a first network port and a second network port, the first and second network ports configurable to be one of at least power sourcing equipment (PSE) and a powered device (PD);
configuring the first network port to be a PD and the second network port to be a PD;
requesting a first amount of power to be provided to the first network port and a second amount of power to be provided to the second network port; and
subsequently detecting an event at the first port, and, responsive thereto, requesting a third amount of power different from the second amount of power to be provided to the second network port.

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.

9. An electronic device, comprising:
-
a first data telecommunications port constructed and arranged to couple to first power sourcing equipment; a second data telecommunications port constructed and arranged to couple to second power sourcing equipment; and electronic circuitry coupled to the first and second data telecommunications ports, the circuitry being constructed and arranged to; configure the first data telecommunications port to operate as a powered device (PD) port with respect to the first power sourcing equipment, while the first data telecommunications port is configured as a PD port, configure the second data telecommunications port to operate as a PD port with respect to the second power sourcing equipment, and in response to an event relating to the first data telecommunications port, changing an amount of power consumed from the second power sourcing equipment. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of operating an electronic device on a wired data telecommunications network, the method comprising:
-
configuring a first data telecommunications port of the electronic device to operate as a powered device (PD) port with respect to first power sourcing equipment coupled to electronic device through the first data telecommunications port; while the first data telecommunications port is configured as a PD port, configuring a second data telecommunications port of the electronic device to operate as a PD port with respect to second power sourcing equipment coupled to electronic device through the second data telecommunications port; and in response to an event relating to the first data telecommunications port, changing an amount of power consumed by the electronic device from the second power sourcing equipment. - View Dependent Claims (18, 19, 20)
