AT-FS717FC/SC Fast Ethernet Switch Installation Guide

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.

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.

100Base-FX

Fiber Optic Port

The AT-FS717FC/SC Fast Ethernet switch features one fiber optic port.

The features of the fiber optic port are explained in the following sections.

Type of Connector

The fiber optic port features a SC connector.

Port Speed

The fiber optic port is 100Base-FX compliant and has fixed operating

speed of 100 Mbps. The end-node connected to the fiber optic port on the

switch must also be able to operate at 100 Mbps.

100FX Duplex Mode Switch

The AT-FS717FC/SC switch has one duplex mode switch for its fiber optic

port, located on the front panel of the chassis. The fiber optic port on the

switch can operate in either half- or full-duplex mode. You must set the

duplex mode manually using the 100FX Duplex Mode Switch.

The 100FX duplex mode switch specifications are as follows:

 Upper position - The fiber optic port is operating in half-duplex

mode.

 Lower position - The fiber optic port is operating in full-duplex

mode.
