Introducing the Router
INTRODUCING THE ROUTER
This Guide takes you through the basic steps necessary to install and configure
your OfficeConnect ADSL Wireless 54 Mbps 11g Firewall Router, and establish
a connection from your computers to the Internet. Throughout this Guide, the
OfficeConnect ADSL Wireless 54 Mbps 11g Firewall Router is simply referred
to as the Router.
Note: 3Com recommends that you use wired (Ethernet) connection to perform
the initial setup.
• One OfficeConnect ADSL Wireless 54 Mbps 11g Firewall Router
• One 12V power adapter for use with the Router
• Four rubber feet
• One RJ11 cable
• One CD-ROM containing the User Guide
• This Installation Guide
• One Support and Safety Information Sheet
• One Warranty Flyer
Before starting, ensure that:
• You already have an ADSL broadband account.
• You have a computer that has an Ethernet connection available and is
already correctly configured for communication with the Internet. Your
computer must be able to connect to the Internet via the modem, and
must have a Web browser installed.
• There are no other DHCP server devices on your local network that are
responsible for allocating IP addresses to your computers and other network
connected devices. Your Router will perform this function by default.
• If you require wireless access, you have a computer that has a wireless
802.11b or 802.11g adapter card installed.
If one or more of these conditions are not met, refer to the OfficeConnect
ADSL Wireless 54Mbps 11g Firewall Router User Guide provided on the
accompanying CD-ROM for further guidance.

FRONT PANEL
1. Alert LED amber
This LED has a number of functions:
• It will flash rapidly during the power up self test. If it then remains on the unit self test has failed
(refer to the User Guide).
• It will flash rapidly during software upgrade.
• It will flash rapidly during the reset to Factory defaults. If the reset button on the rear panel has been
used to reset the unit to Factory defaults the Alert LED will then slow flash until power is removed.
• It will flash on for 2 seconds when the firewall detects a hacker attack.
2. Power LED green
If the LED is on, it indicates that the Router is powered on.
3. SYNC LED green
If the LED is on, it indicates that the DSL connection is present. This LED flashes during configuration at
power up.
4. Online LED green
If the LED is on, it indicates that your Username/Password has been authenticated successfully with your ISP.
5. Wireless LAN (WLAN) Status LED green
If the LED is on, it indicates that wireless networking is enabled. If the LED is flashing, the link is OK and
data is being transmitted or received. If the LED is off, the wireless LAN has been disabled on the Router,
or there is a problem (refer to the User Guide).
6. LAN Status LED green
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 the User

To reboot the Router, press the reset button for 1 second. If you want to reset the Router to factory
defaults or if you cannot access the Web management interface (for example, due to a lost password),
press the reset button for 5 seconds.
10. Power Adapter Socket
Only use the 12V power adapter that is supplied with the Router. Do not use any other adapter.
11. ADSL
The ADSL port is used to connect the Router to the ADSL wall socket connection. Use an RJ11 cable to
connect from the ADSL port to the ADSL wall connection.

1. POSITIONING AND INSTALLING YOUR ROUTER
WARNING: Please read the ‘Important Safety Information’ section in
the Support and Safety Information sheet before you start.
VORSICHT: Bitte lesen Sie den Abschnitt „Wichtige
Sicherheitsinformationen” sorgfältig durch, bevor Sie das Gerät in
Betrieb nehmen.
AVERTISSEMENT: Lisez attentivement le paragraphe “Remarques
relatives à la sécurité” avant de mettre votre routeur sous tension.
When positioning your Router, ensure that:
• The Router is centrally located to the wireless computers that will connect
to it. A suitable location might be on top of a high shelf or similar furni-
ture to optimize wireless connections to computers in both horizontal and
vertical directions, allowing coverage throughout.
• 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.
• To meet FCC radiation exposure regulations, the Router should be located
in a position that maintains a minimum distance of 20 cm (8 inches) from
any personnel (refer to the User Guide for details).
• Water or moisture cannot enter the case of the unit.
• Air flow around the unit and through the vents on the side of the case is
not restricted. 3Com recommends that 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 other flat top units. Only stick
the feet to the marked areas at each corner of the underside of your Router.

Positioning and Installing Your Router
1. Connect the power adapter to the Router and wait for the WLAN LED to
illuminate.
2. Ensure that your computer is switched on.
3. Connect your computer to one of the 10/100 LAN ports on the Router.
The LAN Port Status LED should turn green.
4. Connect the RJ11 cable from the ADSL port on the Router to your ADSL
socket on the wall.
To share your Router with more than four users, you will need an additional
hub or switch. Connect a LAN port on your Router to the hub or switch (for
example, OfficeConnect Dual Speed Switch 8).

Installing a Splitter and Micro-filter

2. INSTALLING A SPLITTER AND MICRO-FILTER
A splitter and micro-filter allow you to use your Router and telephone at the
same time. The splitter connects to the ADSL wall connection, and then pro-
vides two connectors:
•An RJ11 connector which connects to the Router with the RJ11 cable
•A telephone jack connector which can be connected to your telephone
There must also be a micro-filter between the splitter and the telephone. The
micro-filter ensures that DSL data signal does not interfere with the telephone
voice signal. A micro-filter must be installed inline with each telephone to
prevent signal interference. Splitters are now available with built in microfil-
ters, which simplifies the setup as shown in the diagram below. Splitters and
micro-filters can be obtained from your ISP or a computer store.

3. CONNECTING TO YOUR ISP
Before you can configure the Router, you need to know the IP allocation
method used by your ISP. There are four different methods that the Router
can use to connect to the Internet, as described below. For all methods, you
need to know the VPI (Virtual Path Identifier), VCI (Virtual Channel Identifier)
and the Encapsulation (LLC or VC Mux). The Router defaults for the VPI and
VCI should cater for most ISPs. Your ISP can provide you with the required
information.
1. PPPoE
To configure the gateway, you will need to know the user name and password
to log in to your ISP account. If you have been using a PPPoE client on
your computer, you can disable it as it is no longer needed. If your ISP
provides you with a static IP address, enter this IP address in the Internet
Settings section of the Router Web interface. Otherwise, your ISP will
automatically assign your Router an IP address.
2. PPPoA
This is similar to PPPoE but is used mainly in the UK. To configure the
gateway, you will need to know the user name and password to log in to
your ISP account. If your ISP provides you with a static IP address, enter
this IP address in the Internet Settings section of the Router Web interface.
Otherwise, your ISP will automatically assign your Router an IP address.
3. Bridge Mode for a Single Computer (RFC 1483 Bridging Mode)
In this mode, the Router is set into a bridging mode to connect the LAN
and WAN networks. Traffic is limited between the two networks based on
hardware addresses and so limits the LAN side to a single computer.
4. Routing Mode over ATM (RFC 1483 Bridging Mode)
Routing mode over ATM means that the Router has a fixed IP address to
connect to the Internet. Your ISP will provide the Router with a fixed IP
address, the subnet mask and the ISP’s gateway address. You need to
enter this information in the Internet Settings section of the Router Web
interface.

4. RUNNING THE SETUP WIZARD
1. If you have not already done so, restart your computer.
2. Launch your Web browser and try to connect to the Router by typing the
following URL in the address or location bar: http://192.168.1.1. If you
can access the login page, then your computer has correctly received an IP
address from the Router.
3. Log in using the default password <admin>. The Wizard will attempt to
launch automaticallyIf it fails, select Wizard from the menu.
Where possible, the Wizard will recommend settings for most parameters.
However, there are some settings that you must provide. Most of these will
have been provided to you by your ISP when you set your account up.
When the Wizard has completed, attempt to browse to an Internet Web site,
such as www.3com.com. If you can successfully access this site, then you
computer and Router have been configured correctly.
