How the Switch Can Be Used

Switching

When a network of repeater hubs is in operation, any

information that is sent by the workstations is passed

around the whole network (regardless of the destination

of the information) which results in a lot of unnecessary

traffic that can slow it down. The switch solves this

problem because it 'listens' to the network and

automatically learns what workstations can be reached

through its ports. It can then selectively pass on any

information by transmitting the traffic from the relevant

port only (instead of all ports like a repeater hub). This

operation is called 'switching' .

The switch effectively divides up your network,

localizing the network traffic and passing on traffic as

necessary (as shown in the diagram). If you have

workstations that communicate frequently in the same

part of the network, traffic between them is not passed

to the remainder of the network, reducing the load.

If you have any high performance workstations that

require a lot of bandwidth, connect them directly to the

switch.

The Switch Separates Your Network and Controls the Information Effectively

Connecting 10BASE-T and 100BASE-TX Networks

This switch enables you to connect 10BASE-T and

100BASE-TX networks together. This means that if you

have both types of network, you can connect them so all

of your workstations can communicate.

Alternatively, if you want to improve performance by

introducing 100BASE-TX (using an OfficeConnect

Hub 8/TP100 for example), the switch protects your

investments because it maintains 10BASE-T connections

to your original network equipment.

Before You Start

Your OfficeConnect switch comes with:

One power adapter for use with the switch

A Warranty Registration card for you to fill out and return

Four rubber feet

Four stacking clips

An OfficeConnect Product Range sheet

Hub Connections

To connect OfficeConnect hubs to your switch, you

need:

One suitable TP cable for each hub.

Workstation Connections

To connect workstations or other equipment (such as

servers) directly t o your switch ports, you need :

One 10BASE-T or

100BASE-TX adapter card

for each workstation . 3Com

produce a range of easy to

install network adapters,

which provide your

workstation with a

10BASE-T or 100BASE-TX

connection .

O ne suitable TP cable for each workstation.

In order to comply with the 10BASE-T standard, ports

designed for workstation connections have been marked

with the graphical symbol 'x' . This denotes a crossover in

the port's internal wiring, for example 1x, 2x, 3x...

You also need a network operating system running on

your workstations.

Twisted Pair (TP) Cables

To connect your hubs and workstations to the switch,

you must use 'Straight-through' TP cable with RJ45

connectors (all OfficeConnect products use RJ45 type

connectors). Your supplier should stock suitable cables.

Cables can be shielded (screened) or unshielded; we

recommend that you use shielded (screened) cable.

100BASE-TX cable must be data grade (Category 5).

The maximum length you can use is 100 meters

(328 feet).

A 'Straight-through' cable is one where the pins of one

connector are connected to the same pins of the other

connector.
