The control component is configured to: receive a port state indication signal from the main chip, and parse the port state indication signal to obtain usage state information of each logical port; generate N enable signals, and control at most one enable signal to be valid at any time point; and control the states of the N channel indicators by using the N enable signals sent from the enable signal controlling module, and control the state of each port indicator according to the N enable signals and the usage state information of each logical port.
