Introduction
The switch is a multi-port switch that can be used to build high-
performance switched workgroup networks. The switch is a store-and-
forward device that offers low latency for high-speed networking. The
switch is designed for workgroups, departments or backbone computing
environments for SME (small, medium enterprise) businesses.
Use the switch to bridge your network devices.

Applications
This section provides two network topology examples in which the switch
is used.
Standalone Workgroup
In this application, the switch is an ideal solution for small networks
where rapid growth can be expected in the near future.
The switch can be used standalone for a group of heavy traffic users.
You can connect computers directly to the switch’s port or connect other
switches to the switch.
In this example, all computers can share high-speed applications on the
server. To expand the network, simply add more networking devices
such as switches, routers, computers, print servers etc.

5
Bridging
With its large address table and high performance, the switch is an ideal
solution for department networks to connect to the corporate backbone
or for connecting network segments.
The following figure depicts a typical segment bridge application of the
switch in an enterprise environment. The two networks (RD and Sales),
the standalone server and the computers can all communicate with each
other and share all network resources.
