1. A board mis-insertion prevention circuit comprising:
a first detection circuit configured to detect whether a board is in a first state and output a first detection signal when the board is in the first state;
a second detection circuit configured to detect whether the board is in a second state when the board is not in the first state, and output a second detection signal when the board is in the second state; and
a control module electrically connected to the first detection circuit and the second detection circuit, configured to receive the first detection signal or the second detection signal, and disconnect power supply to the board according to the first detection signal or the second detection signal;
wherein the first detection circuit comprises a first light emitting module and a fifth port, an anode of the first light emitting module is electrically connected to the fifth port and the control module, and a cathode of the first light emitting module is connected to a second power supply.
