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.

Wireless 11n ADSL Firewall Router

The 3Com Wireless 11n ADSL 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. The Router can also prevent your users from accessing Web sites which you find unsuitable.

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.

12 CHAPTER 1: INTRODUCING THE ROUTER

Figure 1 Example Network Without a Router

When you use the Router in your network (Figure 2), it becomes your connection to the Internet. Connections can be made directly to the Router, or to an OfficeConnect Switch or Hub, expanding the number of computers you can have in your network.

section in Appendix C

20 CHAPTER 2: INSTALLING THE ROUTER

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 flat top units. Only stick the feet to the marked areas at each corner of the underside of your Router.

Please be careful when you put WL-603 on top of another unit, if the unit underneath is hot, this may impact the reliability of WL-603.

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

wall mounting. The Router must be mounted with the LEDs facing upwards.

When wall mounting the unit, ensure it is within reach of the power outlet. When wall mounting the unit, ensure that the rubber feet are not fixed.

Mounting

Instructions for

Cement Walls

To wall mount the unit:

1 Make two holes 100 mm (3.9 in.) apart and insert two nylon or similar

screw anchors that are suitable for the wall construction.

2 Fix two suitable screws into the anchors, leaving their heads 3 mm (0.12

in.) clear of the wall surface. The screws should be at least 30 mm (1.2 in.) long.

3 Remove any connections in the Router and locate it over the screw heads.

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

Mounting

Instructions for

Wood Walls

Powering Up the Router

To wall mount the unit:

1 Make two holes 100 mm (3.9 in.) apart. 2 Fix two suitable screws directly into the wall, leaving their heads 3 mm

(0.12 in.) clear of the wall surface. The screws should be at least 20 mm (0.75 in.) long.

3 Remove any connections in the Router and locate it over the screw heads.

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

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

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.

Connecting the Router

The first step for installing your Router is to physically connect it to the telephone socket and then connect it to a computer in order to be able to access the Internet. See Figure 5:

22 CHAPTER 2: INSTALLING THE ROUTER

Figure 5 Connecting the Router

1 Run the provided telephone cable from the wall jack providing ADSL

service to the ADSL port on your Router. When inserting an ADSL RJ-11 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. If you are using splitterless ADSL service, add low-pass filters between the ADSL wall jack and your telephones. (These filters pass voice signals through but filter data signals out.)

2 Then:

■ If you are using a full-rate (G.dmt) connection, your service provider

will attach the outside ADSL line to a data/voice splitter. In this case you can connect your phones and computer directly to the splitter as shown below (Figure 6):

■ If you are using a splitterless (G.lite) connection, then your service

provider will attach the outside ADSL line directly to your phone system. In this case you can connect your phones and computer directly to the incoming ADSL line, but you will have to add low-pass filters to your phones as shown below (Figure 7)
