INTRODUCTION

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 increases, heavier demands are made on the available network bandwidth that if unchecked, can lead to performance problems in a hub-based setup. Installing the OfficeConnect Dual Speed Switch 5 (3C16790) or Switch 8 (3C16791) allows your network to be segmented so that traffic can be contained effectively, reducing the overall load without affecting access to critical resources.

This guide will use the term 'Switch' when referring to the Dual Speed Switch 5 or Switch 8.

The Switch is ideal for use with other OfficeConnect products, as shown in Figure 1. It is compact and attractively designed for desktop use. The Switch is part of the OfficeConnect range which neatly stack together with the OfficeConnect Stacking Clip.
