INTRODUCTION
About This Guide:
Welcome to the world of networking with 3Com. In the
modern business environment, communication and sharing
information is crucial. Computer networks have proved to be
one of the fastest modes of communication but until recently,
only large businesses could afford the networking advantage.
The OfficeConnect
®
product range from 3Com has changed
this, bringing networks to the small office.
As the power of workstations and business applications increas-
es, heavier demands are made on the available network band-
width that if unchecked, can lead to performance problems in
a hub-based setup. Installing the 3Com
®
OfficeConnect Fast
Ethernet Switch 5 (3C16790C) or Switch 8 (3C16791C) allows
your network to be segmented so that traffic can be contained
effectively, reducing the overall load without affecting access to
critical resources. This switch has one of the most compact
designs in the industry making it ideal for desktop use. It can
be used with other units in the OfficeConnect family, which
include Cable/DSL gateways, wireless devices, Fast Ethernet and
Gigabit Ethernet switches. The OfficeConnect family is a fully
integrated system, enabling you to share computer resources,
and take advantage of new technologies as your network grows.
