Maximum Distance
Each twisted-pair port has a maximum operating distance of 100 m
(328 feet).
Type of Cabling
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.
Auto MDI/MDI-X
All of the twisted-pair ports on these switches 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.
System and Port
LEDs
The system and port LEDs on the front panel of the AT-FS724L switch
display the switch and its port status information. Each port has two LEDs.
Table 1 describes the system and twisted-pair port LEDs on the AT-
FS716L and AT-FS724L Fast Ethernet switches.
