Port LEDs and Modes
Each Ethernet port has a port LED. These port LEDs, as a group or individually, display information about the switch and about the individual ports. To select or change a mode, press the Mode button until the desired mode is highlighted. When you change port modes, the meanings of the port LED colors also change.
