Gigabit Ethernet
This section provides technical specifications for Gigabit Ethernet cards.
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 that indicate what speed (10, 100, or 1000 Mbit/s) the link has been established.
The following tables show the LED description and status for the 1000Base-SX (Table
A-1) and 1000Base-T (Table A-2).
