Type of Cabling
For 10 Mbps operation, Category 3 or better 100 ohm shielded or
unshielded twisted pair cabling is required. For 100 or 1000 Mbps
operation, Category 5 and Enhanced Category 5 (5E) 100 ohm shielded
or unshielded twisted pair cabling is required.
Auto MDI/MDI-X
All of the twisted pair ports on the switch are auto-MDI and IEEE 802.3ab-
compatible. When a port's speed and duplex mode are set through Auto-
Negotiation, the port uses the auto-MDI feature to automatically configure
itself as MDI or MDI-X when connected to an end-node. Consequently,
you can use either a straight-through or crossover twisted pair cable when
connecting any network device to a port.
The system and port LEDs on the front panel of the AT-GS900/16 and
AT-GS900/24 switches display the switch and its port status information.
Each port has two LEDs.
