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 (SPD, DX, or
EN) is lit.
