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.

POSITIONING YOUR GATEWAY

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.

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

The Ethernet Cable/DSL port is configured as MDI, for

connection to your modem with the supplied straight-

through patch cable. 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.
