Network Topologies
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.

Topology
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.
