Port LEDs
Before you can understand what the port LEDs mean, you should be aware of the
functions and relationships of the MODE button, A/L LED, and D/S LED:
1) Only one of the A/L and D/S mode LEDs can light at one time. You can
toggle between them using the MODE LED. If A/L mode LED is ON, the
yellow/green LED for each port indicates the ACTIVE/LINK state of the port;
if D/S mode LED is ON, the mode of DUPLEX/SPEED.
A/L mode LED lights each time the switch is initialized.
2)
3) D/S mode LED can light for a maximum of 45 seconds each time after you
toggle to it; and after that, A/L mode resumes. You can also toggle to the A/L
mode before that time by pressing the MODE button.
