System and method for operating a sensed power device over data wiring |
摘要 |
According to the present invention, a power source delivers power to a networked device over network cabling (e.g., Ethernet cabling) in one of two modes: a low power mode and a high power mode. The power source begins delivering power at a low power level in the low power mode, and switches to a high power level in the high power mode after a communication exchange between the networked device and the power source. A power source delivery system includes circuitry on both the power source and the powered device for communicating information between the devices.
