Description

The port LEDs on the front panel display port status information. Each

port has two LEDs. The Link LED indicates whether there is a valid link

between a port and the end node connected to it.

Each port also has a Mode LED. This LED displays a variety of status

information, including port speed and duplex mode. You use the Mode

Select button on the front panel to toggle the Mode LEDs to display

different status information. The LEDs next to the Mode Select button

indicate the status being displayed by the port Mode LEDs. For example,

if the Mode 100 LED is lit, then the port Mode LEDs are displaying port

speed.

Note

Toggling the Mode Selection button does not affect the normal

operations of the switch.
