Application Examples
The Gigabit Ethernet Switches are 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.

The Gigabit Ethernet Switches are an excellent choice for mixed Ethernet, Fast
Ethernet, and Gigabit Ethernet installations where significant growth is expected in
the near future. In a basic stand-alone configuration, it can provide direct full-duplex
connections for up to 24/48 workstations or servers. 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 connect to another hub or switch
using one of the Gigabit Ethernet ports built into the front panel, or a Gigabit
Ethernet port on a plug-in SFP transceiver.
In the figure below, the 48-port Gigabit Ethernet Switch 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 1 Gbps
full-duplex connections to servers.
