Welcome to the world of networking with 3Com

®

.

In the modern business environment, communication 
and sharing information are crucial. Computer 
networks have proved to be one of the fastest modes 
of communication. The OfficeConnect

®

 product 

range from 3Com brings the power of computer 
networks to the small office.

The OfficeConnect Dual Speed Hub 16 is an 
easy-to-use Class II

 

hub (repeater) with 16 

10/100BASE-TX ports. It allows you to set up a 
network with both Ethernet (10Mbps) and Fast 
Ethernet (100Mbps) workstations and other devices 
(a Class II hub can be connected to another Fast 
Ethernet hub, a Class I hub cannot).

When referring to the OfficeConnect Dual Speed 
Hub 16, this guide uses the term ‘Hub’.

Each port on the Hub can be connected to either a 
10BASE-T (Ethernet) or a 100BASE-TX (Fast Ethernet) 
device. The port senses the speed of the connected 
equipment and operates at the appropriate speed.

If you wish to extend an existing Ethernet network 
into Fast Ethernet, adding a Dual Speed Hub 16 can 
offer a more cost-effective migration path than 
adding both a 100Mbps hub and a 10/100Mbps 
switch.

Small Network with OfficeConnect Dual Speed Hub 16

The Hub is ideal for use with other OfficeConnect 
products. The OfficeConnect product range is 
compact and attractively designed for desktop use, 
and neatly stacks together with clips. For further 
information, refer to the “OfficeConnect Product 
Range”  sheet that accompanies the Hub.

This guide helps you get the most out of your Hub.
