The Meaning of the LEDs

The Link LED indicates the card’s status and must be on for the card to function properly. Note that there is no Link LED on the 1000Base-T card. In its place are three LEDs which indicate what speed (10, 100, or 1000 Mbps) the link has been established.

The following tables show the LED description and status.
