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.
The OfficeConnect Ethernet Hub 16C is ideal for creating small networks. It is compact and attractively designed for desktop use. This product forms part of the OfficeConnect range which neatly stack together with the OfficeConnect stacking clip.
When referring to the OfficeConnect Ethernet Hub 16C, this guide uses the term ‘OfficeConnect hub’.
A single OfficeConnect hub allows you to create a small network with up to sixteen workstations, as shown in Figure 1.

If you need to connect more workstations, simply use the stacking clip to connect another OfficeConnect hub to form a stack (each hub is a single repeater).
The OfficeConnect Ethernet Hub 16C has sixteen 10BASE-T ports and one 10BASE-2 (Coaxial) connector.
