INTRODUCING THE ROUTER

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 all this, bringing networks to the small office.

The products that compose the OfficeConnect range give you, the small office user, the same power, flexibility, and protection that has been available only to large corporations. Now, you can network the computers in your office, connect them all to a single Internet outlet, and harness the combined power of all of your computers.

OfficeConnect ADSL Wireless 108Mbps 11g Firewall Router

The OfficeConnect ADSL Wireless 108Mbps 11g Firewall Router is designed to provide a cost-effective means of sharing a single broadband Internet connection amongst several wired and wireless computers. The Router also provides protection in the form of an electronic “firewall”, preventing anyone outside of your network from seeing your files or damaging your computers.

features such as scheduled internet access policies, web content filter, and intrusion detections.

Figure 1 shows an example network without a Router. In this network,

only one computer is connected to the Internet. This computer must always be powered on for the other computers on the network to access the Internet.

The Router also gives you many administrative

18 CHAPTER 1: INTRODUCING THE ROUTER

HARDWARE INSTALLATION

Introduction This chapter will guide you through a basic installation of the Router,

including:

■ Connecting the Router to the Internet.

■ Connecting the Router to your network.

■ Setting up your computers for networking with the Router.

Safety Information

Positioning the Router

WARNING: Please read the “ before you start.

VORSICHT: Bitte lesen Sie den Abschnitt “ sorgfältig durch, bevor Sie das Gerät einschalten.

AVERTISSEMENT: Veuillez lire attentivement la section “

importantes de sécurité” avant de mettre en route.

You should place the Router in a location that:

■ is conveniently located for connection to the telephone socket that

will be used to connect to the Internet.

■ is centrally located to the wireless computers that will connect to the

Router. A suitable location might be on top of a high shelf or similar

furniture to optimize wireless connections to computers in both

horizontal and vertical directions, allowing wider coverage.

■ allows convenient connection to the computers that will be connected

to the four LAN ports on the rear panel, if desired.

■ allows easy viewing of the front panel LED indicator lights, and access

to the rear panel connectors, if necessary.

Wichtige Sicherheitshinweise”

Consignes

20 CHAPTER 2: HARDWARE INSTALLATION

When positioning your Router, ensure:

■ It is out of direct sunlight and away from sources of heat.

■ Cabling is away from power lines, fluorescent lighting fixtures, and

sources of electrical noise such as radios, transmitters and broadband amplifiers.

■ Water or moisture cannot enter the case of the unit.

■ Air flow around the unit and through the vents in the side of the case

is not restricted. 3Com recommends you provide a minimum of 25 mm (1 in.) clearance.

Using the Rubber

Feet

Use the four self-adhesive rubber feet to prevent your Router from moving around on your desk or when stacking with other flat top OfficeConnect units. Only stick the feet to the marked areas at each corner of the underside of your Router.

Stacking the Router If you are stacking your Router with other OfficeConnect units, install the

Router at the top of the stack. Refer to the documentation supplied with your other OfficeConnect unit for details on using the stacking clip.

A stacking clip is not supplied with the Router. Use the stacking clip supplied with another stackable OfficeConnect unit.

Wall Mounting There are two slots on the underside of the Router that can be used for

wall mounting.

When wall mounting the unit, ensure that it is within reach of the power

Do not install the Router more than 200 cm above the ground.

outlet.

You will need two suitable screws to wall mount the unit. To do this:

1 Ensure that the wall you use is smooth, flat, dry and sturdy and make two

screw holes which are 150 mm (5.9 in.) apart.

2 Fix the screws into the wall, leaving their heads 3 mm (0.12 in.) clear of

the wall surface.

3 Remove any connections to the unit and locate it over the screw heads.

When in line, gently push the unit on to the wall and move it downwards to secure.

Before you Install your Router 21

When making connections, be careful not to push the unit up and off the wall.

CAUTION: Only wall mount single units, do not wall mount stacked units.

Before you Install your Router

Before you install and configure your Router, you need the following additional information. If you do not have this information, contact your Internet Service Provider (ISP). Space is provided below for you to record this information.

If you have a DSL connection and your ISP allocates IP information dynamically over PPPoE, (or PPPoA, which is in common use in the UK), you need a User Name and Password:

PPPoE User Name : ______________________

PPPoE Password : ______________________

PPPoE Service Name : ______________________

You only need a PPPoE Service Name if your ISP requires one. Do not enter anything if your ISP does not require this information.

You should leave the Authentication Method as its default: Auto if your ISP does not specify this parameter.

If your ISP allocates fixed or static IP information, you need the following information:

IP Address : ____.____.____.____

Subnet Mask : ____.____.____.____

Default Router address : ____.____.____.____

DNS address : ____.____.____.____

22 CHAPTER 2: HARDWARE INSTALLATION

If your ISP allocates IP information dynamically over a protocol other than PPPoE, you do not need any further information. This configuration is typical of cable connections.

Powering Up the Router

Connecting the Router

To power up the Router:

1 Plug the power adapter into the power adapter socket located on the

back panel of the Router.

2 Plug the power adapter into a standard electrical wall socket.

The first step for installing your Router is to physically connect it to an RJ11or RJ45 cable, as appropriate, with the splitter and then connect the Router to a computer in order to be able to access the Internet. See

Figure 5:

To use your Router to connect to the Internet through an DSL connection:

1 Insert one end of the supplied telephone (RJ-11) cable into the ADSL port

on the rear panel of the Router. Check that the DSL Sync status LED lights on the Router.

2 Connect your computer to one of the four LAN ports on the Router using

a Category 5 twisted pair cable. Check that the corresponding LAN status LED on the Router lights.

Connecting the Router 23

You have now completed the hardware installation of your Router. Next you need to set up your computers so that they can make use of the Router to communicate with the Internet.

3Com recommends that you perform the initial Router configuration from a computer that is directly connected to one of the LAN ports.

If you configure the Router from a wireless computer, note that you may lose contact with the Router if you change the wireless configuration.

To communicate wirelessly with your Router, your wireless NIC should be set as follows:

■ Encryption — none

■ Service Area Name/SSID — 3Com

■ Channel — 11

24 CHAPTER 2: HARDWARE INSTALLATION

SETTING UP YOUR COMPUTERS

The Router has the ability to dynamically allocate network addresses to the computers on your network, using DHCP. However, your computers need to be configured correctly for this to take place. To change the configuration of your computers to allow this, follow the instructions in this chapter. If your computers are configured with fixed or static addresses and you do not wish to change this, then you should use the Discovery program on the Router CD-ROM to detect and configure your Router. Refer to Appendix A program.
