Connecting the Gateway to the Internet.

Connecting the Gateway to your network.

Positioning the Gateway

You should place the Cable/DSL Secure Gateway in a location that:

is conveniently located for connection to the cable or DSL modem that will be used to connect to the Internet.

allows convenient connection to the computers that are to be connected to the four LAN ports on the rear panel.

Safety Information

WARNING: Please read the “Important Safety Information” section in Appendix D 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:

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. We recommend you provide a minimum of 25mm (1in.) 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 flat top OfficeConnect units. Only stick the feet to the marked areas at each corner of the underside of your Gateway.
