Application Examples
The Gigabit Ethernet Switch is not only designed to segment your network, 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.
Collapsed Backbone
The Gigabit Ethernet 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 either a 10G transceiver or a 10 Gigabit Ethernet port
on an optional module.
In the figure below, the 24-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.
