Application Examples
The SF-2420GX switch 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 switch is 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 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, a Gigabit Ethernet port on a plug-in
SFP transceiver, or a 10G transceiver on an optional module.
In the figure below, the 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.
