10/100BASE-TX Autosensing Ethernet Port Status LED
There are two port status LEDs on both sides (yellow LED on the left and green LED
on the right) of the 10/100BASE-TX Ethernet port on the Switch 4210 PWR
models. They indicate the port's active, link, duplex, and speed status.
In addition, there is an A/L LED and a D/S LED on each Switch 4210 PWR model.
These two LEDs indicate the port status LEDs mode. When the A/L LED is on, the
port status LEDs respectively indicate the port's active status and link status. When
the D/S LED is on, the port status LEDs respectively indicate the port's duplex status
and speed status. Either the A/L LED or the D/S LED is on at one time. For details,
see Table 4.

You can change the mode of the port status LEDs by pressing the Mode button.
After a switch is powered on, the A/L LED is on initially. If you press the Mode
button, the D/S LED will be on. After that, if you press the Mode button again
within 45 seconds, the A/L LED will be on again. Otherwise, the A/L LED will
automatically be on 45 seconds later.
