Network Planning
Application Examples
The SMC8126PL2-F 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 SMC8126PL2-F 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 26 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 26-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. In addition, connected IP phones and wireless
access points are receiving PoE power from the switch.
