Chapter 1: Product Description

For 10 Mbps operation, Category 3 or better 100 ohm shielded or

unshielded twisted pair cabling is required. For 100 Mbps operation,

Category 5 and Enhanced Category 5 (5E) 100 ohm shielded or

unshielded twisted pair cabling is required.

Maximum Distance

Each twisted pair port has a maximum operating distance of 100 meters

(328 feet).

Auto MDI/MDI-X

All of the twisted pair ports on the switch are auto-MDI and IEEE 802.3ab-

compatible. The ports use the auto-MDI feature to automatically configure

themselves as MDI or MDI-X when connected to an end-node.

Consequently, you can use a straight-through twisted pair cable to

connect any network device to a port.

System and Port

LEDs

The system and port LEDs on the front panel of the AT-FS705L switch

display status information. Each port has three LEDs. Table 2 describes

the system and port LEDs on the AT-FS705L Fast Ethernet switch.

ECOFriendly

Push Button

The ecoFriendly switch on the front panel may be used to turn ON or OFF

the port LEDs. You can select the OFF position for power conservation.

The power LED remains active at all times.
