Application Examples
APPLICATION EXAMPLES
The Gigabit Ethernet Switches are not only designed to segment your net work,
but also to provide a wide range of options in setting up network connections
and linking VLANs or
IP
subnets.
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 f ull-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 E thernet ports buil t into the fr ont panel , a
Gigabit Ethernet port on a plug-in SFP transceiver, or a 10G transceiver on an
optional module.
In the figure below, the 48-port Gigabit Ethernet Switch is operating as a
collapsed backbone for a small LAN. It i s provi din g dedi c a ted 10 Mbps full-
duplex connections to workstations and 100 Mbps full-duplex connecti on s to
power users, and 1 Gbps full-duplex connection s to servers .
