Topology

This section illustrates two network topologies that you can create with the AT-8000/8POE Fast Ethernet Switch: a power workgroup and collapsed backbone. Both types of topologies are described below.

The topology shown in Figure 4 is commonly referred to as a power workgroup topology. Two AT-8000/8POE Fast Ethernet switches are connected to an AT-9424T Gigabit Ethernet Switch, one via an RJ45 connection and the other using a fiber optic connection. Access points and IP phones are connected to the switches as PoE devices. The access points, in turn, support a wireless Ethernet network of laptop users.
