AT-8500 Series Layer 2+ Fast Ethernet Switches Installation Guide

Figure 11 illustrates a network of three AT-8524M Fast Ethernet switches. The workstations and servers on the network are connected either directly to a switch or indirectly through an Ethernet hub. The switches themselves are connected together through 1000Base fiber optic ports on AT-A45/SC expansion modules, creating a high-speed backbone.
