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.
OfficeConnect ADSL
Wireless 11g
Firewall Router
The OfficeConnect ADSL Wireless 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. 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.

CHAPTER 1: INTRODUCING THE ROUTER
Minimum System
and Component
Requirements
Physical Features
Your Router requires that the computer(s) and components in your
network be configured with at least the following:
■
A computer with an operating system that supports TCP/IP
networking protocols (for example Windows 98/NT/Me/2000/XP, Unix,
Mac OS 8.5 or higher).
■
An Ethernet 10 Mbps or 10/100 Mbps NIC for each computer to be
connected to the four-port switch on your Router.
■
An 802.11b or 802.11g wireless NIC.
■
An active ADSL subscription and connection.
■
A Web browser that supports JavaScript, such as Netscape 4.7 or
higher, Internet Explorer 5.0 or higher, or Mozilla 1.2.1 or higher.
The front panel of the Router contains a series of indicator lights (LEDs)
that help describe the state of various networking and connection
operations.

If the LED is on, the link between the port and the next piece of network
equipment is OK. If the LED is flashing, the link is OK and data is being
transmitted or received. If the LED is off, nothing is connected, or the
connected device is switched off, or there is a problem with the
connection (refer to Chapter 6 “Troubleshooting”). The port will
automatically adjust to the correct speed and duplex.
The rear panel (Figure 4) of the Router contains four LAN ports, one ADSL
port, a reset button, a power switch, and a power adapter socket.

Only use the power adapter that is supplied with this Router. Do not use
any other adapter.
9 Reset Button
If you want to reset your Router to factory default settings, and cannot
access the web management interface (for example, due to a lost
password), then you may use this button. Refer to “Forgotten Password
and Reset to Factory Defaults” on page 104 for further details.
10 Power Switch
Push this switch to the “in” position to turn the unit on. In the “out”
position, the unit is off.
11 Ethernet Ports
Using suitable RJ45 cables, you can connect your Router to a computer,
or to any other piece of equipment that has an Ethernet connection (for
example, a hub or a switch). These ports have an automatic MDI/MDIX
feature, which means either straight-through or a crossover cable can be
used.

Introduction
Safety Information
INSTALLING THE ROUTER
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.
Please note the following:
WARNING: Please read the “Safety Information” section in Appendix C
before you start.
VORSICHT: Bitte lesen Sie den Abschnitt “Wichtige Sicherheitshinweise”
sorgfältig durch, bevor Sie das Gerät einschalten.
AVERTISSEMENT: Veuillez lire attentivement la section “Consignes
importantes de sécurité” avant de mettre en route.
Positioning the
Router
You should place the Router in a location that:
■
is conveniently located for connection to the telephone socket.
■
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.
18
CHAPTER 2: INSTALLING THE ROUTER
When positioning your Router, ensure:
Using the Rubber
Feet
Powering Up the
Router
■
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.
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.
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.
3 Press the power button located on the back of the Router.
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:

1 Run the provided telephone cable from the wall jack providing ADSL
service to the ADSL port on your ADSL 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):
or
■
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)
20
CHAPTER 2: INSTALLING THE ROUTER
Figure 6 Installing with a splitter
Connecting the Router
21
Figure 7 Installing without a splitter
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
■
SSID — 3Com
■
Channel — 11
22
