State and Description
Blinking—The port and the link are active, and there is link activity.
On steadily—The port and the link are active, but there is no link activity.

Figure 6 on page 9 shows the LEDs that indicate the status of one of the three port
parameters—speed, duplex mode, and administrative status. Use the Mode button on
the far right side of the front panel to display the status LED for the different port
parameters. You can tell which port parameter (speed, duplex mode, or administrative
status) is indicated by the ST LED by looking at which port parameter LED (
EN ) is lit.
