AT-GS908 Gigabit Ethernet Switch Installation Guide

Auto-MDI

For port speeds of 10 or 100 Mbps, the ports are auto-MDI. They

automatically configure themselves as either MDI or MDI-X. This feature

allows you to use either straight-through or crossover twisted pair

cables to connect devices to the ports. For port speeds of 1000 Mbps,

you must use a straight through twisted pair cable.

LEDs The port LEDs on the front panel display port status information. Each

port has four LEDs.
