About This Guide:

This Guide takes you through the basic steps necessary to install and configure
your OfficeConnect Wireless Cable/DSL Gateway, and establish a connection
from your computers to the Internet. Throughout this guide the OfficeConnect
Wireless Cable/DSL Gateway is simply referred to as the Gateway.

Note:

3Com recommends that the Gateway is configured from a wired

Ethernet computer during the initial set-up. 

Your package contains:

One OfficeConnect Wireless Cable/DSL Gateway

One power adapter for use with the Gateway

Four rubber feet

One Ethernet cable

One CD-ROM containing the Gateway Discovery program and the User Guide

This Installation Guide

One Support and Safety Information Sheet

One Warranty Flyer

System Requirements

Before starting, you must ensure the following:

You already have a cable or DSL broadband connection to the Internet, with 
a suitable modem, and that this connection works properly. The modem 
must have an Ethernet port for connection to your Gateway.

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 Gateway will now perform this function by default.

You have a computer with a wireless 802.11b adapter card installed.

If one or more of these conditions are not met, refer to the comprehensive Gateway

User Guide provided on the accompanying CD-ROM for further guidance.

Safety Information

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 einschalten.

AVERTISSEMENT:

Veuillez lire attentivement la section "Consignes

importantes de sécurité" avant de mettre en route.

When positioning your Gateway, ensure:

The unit is centrally located to the wireless computers that will connect
to the Gateway. A suitable location might be on top of a high shelf or
similar furniture to optimise 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.

In order to meet FCC radiation exposure regulations the Gateway 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 in the side of the case
is not restricted. We recommend you provide a minimum of 25 mm 
(1 in.) clearance.

Using the Rubber Feet

Use the four self-adhesive rubber feet to prevent your Gateway 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 Gateway.

4 Wireless LAN (WLAN) Status LED 

(yellow)

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 in the Gateway, or there
is a problem (refer to the User Guide).

5 Cable/DSL Status LED

green (100Mbps link) / yellow (10Mbps link)

If the LED is on, the link between the Gateway and the
cable or DSL modem 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, the modem is switched
off or there is a problem (refer to the "Problem Solving"
section).

6 Wireless Antennae

The antennae on the product should be placed in a ‘V’
position when initially installed.

7 Power Adapter socket

Only use the power adapter that is supplied with this
Gateway. Do not use any other adapter.

8 Ethernet Cable/DSL port

Use the supplied patch cable to connect the Gateway
to the Ethernet port on your cable or DSL modem. The
port will automatically adjust to the correct speed and
duplex.

9 Four 10/100 LAN ports

Using suitable RJ45 cable, you can connect your
Gateway to a computer, or to any other piece of
equipment that has an Ethernet connection (for
example, a hub or a switch). The LAN ports are
configured as MDIX, for connection to a computer
with a straight through RJ-45 cable.

1 Alert LED 

(orange)

Indicates a number of different conditions, as described
below.

Off

- The Gateway is operating normally.

Flashing quickly

- Indicates one of the following

conditions:

• The Gateway has just been started up and is

running a self-test routine, or

• The administrator has invoked the 

Reset to Factory

Defaults

command, or

• The system software is in the process of being

upgraded

In each of these cases, wait until the Gateway has
completed the current operation and the alert LED 
is Off.

Flashing slowly

- The Gateway has completed the 

Reset

to Factory Defaults

process, and is waiting for you to

reset the unit. To do this, remove power, wait 10 seconds
and then re-apply power. The Gateway will then enter

the start-up sequence and resume normal operation.

On for 2 seconds, and then off

- The Gateway has

detected and prevented a hacker from attacking your
network from the Internet.

Continuously on

- A fault has been detected with your

Gateway during the start-up process. Refer to the main
User Guide.

2 Power LED 

(green)

Indicates that the Gateway is powered on.

3 Four LAN Status LEDs

green (100Mbps link) / yellow (10Mbps link)

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 "Problem Solving" section). The
port will automatically adjust to the correct speed and
duplex.
