Visual and self-repairing PoE switch

The utility model provides a visual and self-repairing PoE switch, relates to the technical field of communication, and particularly relates to a PoE switch. The visual and self-repairing PoE switch comprises a machine shell, a monitoring MCU module, a power supply system module, a display module, a PoE system module and a switch system module. The monitoring MCU module is respectively connected with the display module, the PoE system module and the switch system module via a bus. The visual and self-repairing PoE switch is characterized in that the monitoring MCU module monitors the working state of the PoE system module in real time. The related information can be displayed via the display module, and normal work of the PoE switch can be recovered by resetting the PoE system module. With application of the aforementioned technical scheme, the monitoring MCU module is respectively connected with the PoE system module and the switch system module via the bus to read the working state of the PoE system module and the switch system module. An MCU microcontroller unit module further analyzes the information, and the working state of the PoE system module and the switch system module is visually displayed on an LCD display screen.
