Auto-sensing 10/100Base- TX 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
each 10/100Base-TX Ethernet port of S3100-T-SI, S3100-C-SI, S3100-TP-PWR-EI and
S3100-C-EPON-EI series. They indicate the active, link, duplex, and speed statuses of the port.
In addition, there are an A/L LED and a D/S LED on each model of S3100-T-SI, S3100-C-SI,
S3100-TP-PWR-EI and S3100-C-EPON-EI series. These two LEDs indicate the mode of the port status
LEDs. When the A/L LED is on, the port status LEDs respectively indicate the active status and link
status of ports. When the D/S LED is on, the port status LEDs respectively indicate the duplex status
and speed status of ports. Either the A/L LED or the D/S LED is on at a specific time. For details, see
