AT-FS709FC Series Installation Guide
If you need to connect together multiple AT-FS709FC Series switches, you might again consider constructing a collapsed backbone topology. But rather than using an AT-FS709FC switch as the backbone switch, you could use a Fast Ethernet switch that has multiple fiber optic ports and connect the AT-FS709FC Series switches using the fiber optic ports. Since the fiber optic port on the AT-FS709FC Series switch has a maximum operating distance of 2 kilometers (1.25 miles), you can connect together switches that are physically separated by large distances.
An example of this topology is illustrated in Figure 5. Eight AT-FS709FC Series Ethernet switches have been interconnected using an AT-8216FXL Fast Ethernet Switch.
