Electrical port module

The invention provides an electric port module, which comprises a circuit board, a network port terminal, a PHY chip and an MCU, the PHY chip and the MCU are arranged on the circuit board, the end part of the circuit board is provided with a golden finger comprising an I2C and a multiplexing pin, and a state register value corresponding to the link state of the network port terminal is stored in a state register in the PHY chip; the MCU is connected with the I2C pin, the multiplexing pin and the PHY chip so as to send a corresponding level signal to the multiplexing pin according to the state register value; a second register in the MCU stores different register values, and the MCU performs corresponding function setting on the multiplexing pin according to the register values, so that the multiplexing pin simultaneously has a network port state indication function and a signal LOS function, and a link state and a signal LOS state of a network port side are obtained according to a level signal of the multiple
