Mid-span automatic transfer switch for power over ethernet lighting and powered devices

A mid-span automatic transfer switch acts as a backup for power sourcing equipment to provide power and at least one backup data signal for power over ethernet lighting and powered devices, where a backup power switch detects a loss of utility power and switches to a source of emergency power in the event utility power is no longer available, a power supply is connected to said backup power switch, comprising:

• a carrier board includes a carrier microcontroller;
• and
• at least one transfer switch module includes a microcontroller, a power transfer device, a digital data switch and a PoE power monitor, said at least one transfer switch module is retained on said carrier board, said carrier microcontroller communicates with said microcontroller, the power supply provides power to said at least one transfer switch module, said PoE power monitor receives a plurality of signals from said power transfer device, said power transfer device receives an output from a plurality of input transformers, said PoE power monitor sends a signal to said microcontroller when a loss of at least one of voltage and current occurs, said microcontroller instructs said power transfer device to receive electrical power from a power sourcing equipment device instead of a plurality of input transformers, said microcontroller contains the at least one backup data signal for any device connected to said at least one transfer switch module, said microcontroller instructs said digital data switch to receive the at least one backup data signal from said microcontroller instead of a plurality of input transformers, wherein the power transfer device supplies a lighting device and a powered device with electrical power, said microcontroller supplies the at least one backup data signal to the lighting device and the powered device, the lighting device and the powered device both require electrical power and the at least one backup data signal to operate, one of the lighting device and the powered device is connected to said at least one transfer switch module.
