Abstract: A network switch displays a state signal of network connection ports by a combination of LEDs and includes a signal management unit, a control unit, switch members, and the LEDs. The signal management unit receives the state signal from the network connection ports and transmits data to the control unit to control each of the switch members and correspondingly output to control each of the LEDs. The state signal includes that a first state data outputs an active/inactive state via a first control signal, a second state data and a third state data output a link-down/up state and a connection speed state via a second control signal, so that the LEDs displays different states of the network connection ports based on a combination of each of the first control signal and each of the second control signal.
