Application Examples
The EdgeIron 4802CF is not only designed to segment your network, but
also to provide a wide range of options in setting up network connections.
Some typical applications are described below.
Collapsed Backbone
The EdgeIron 4802CF is an excellent choice for mixed Ethernet and Fast
Ethernet installations where significant growth is expected in the near
future. You can easily build on this basic configuration, adding direct full-
duplex connections to workstations or servers. When the time comes for
further expansion, just cascade the EdgeIron 4802CF to an Ethernet or
Fast Ethernet hub or switch.
In the figure below, the EdgeIron 4802CF is operating as a collapsed
backbone for a small LAN. It is providing dedicated
10 Mbps full-duplex
connections to workstations and
100 Mbps full-duplex connections to
power users and servers.
