10/100Base-TX Ethernet port LED
Each 10/100Base-TX auto-sensing Ethernet port has a status LED to show port operating status and
activities. The port mode LED shows the type of port status information (for example, port rate or duplex
mode) that the port status LEDs are showing. You can use the port status LED mode switching button to
change the type of displayed port information.
