Positioning Your OfficeConnect Hub When installing your Hub, ensure: 3 It is out of direct sunlight and away from sources of heat. 3 Cabling is away from power lines, fluorescent lighting fixtures, and sources of electrical noise such as radios, transmitters and broadband amplifiers. 3 Water or moisture cannot enter the case of the unit. 3 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. Wall Mounting the OfficeConnect Hub CAUTION: Only wall mount single units. Do not wall mount stacked units. There are two slots on the underside of the Hub which are used for wall mounting. You can mount the unit with the LEDs facing upwards or downwards, to suit your needs. When wall mounting the unit, ensure that it is within reach of the power outlet. You need two suitable screws. Ensure that the wall you are going to use is smooth, flat, dry and sturdy. Make two screw holes which are 142mm (5.6in.) apart. Use the guide at the top of this page to mark the position of the holes. Fix the screws into the wall, leaving their heads 3mm (0.12in.) clear of the wall surface. Remove any connections to the unit and locate it over the screw heads. When in line, gently push the unit on to the wall and move it downwards to secure. When making connections, be careful not to push the unit up and off the wall. Connecting Workstations and Other Equipment to Your Hub WARNING: Ensure you have read the Important Safety Information section carefully before you start. ACHTUNG: Versichern Sie sich, daß Sie den Abschnitt mit den wichtigen Sicherheitshinweisen gelesen haben, bevor Sie das Gerät benutzen. AVERTISSEMENT: Assurer que vous avez lu soigneusement la section de L'information de Sécurité Importante avant que vous commenciez. CAUTION: The equipment connected to the Hub must be set to operate in auto-negotiate or half duplex mode. Connecting workstations and other equipment to your Hub is easy. To connect a workstation to any of the Hub's ports, use a 'straight-through' TP cable. Refer to "Twisted Pair (TP) Cables" on page 3 for further information. If you are using port 8 to connect a workstation, ensure the MDI/MDIX switch is set to MDIX (out). TP cables are very easy to use. To connect a cable, simply slot the connector into the appropriate RJ45 port. When the connector is fully in, its latch locks it in place. To disconnect the cable, push the connector's latch in and remove it. The Hub detects all port connections, so you can start using your network immediately. If you need more ports, simply add another OfficeConnect hub. 4
