Connecting Workstations and Other Equipment to Your Hub

WARNING: Please read the ‘Important Safety Information’ section before you start.

WARNHINWEIS: 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.

CAUTION: Do not power the hub off and on quickly. Wait about five seconds between power cycles.

Connect workstations and other equipment to any of the hub’s 10BASE-T RJ-45 ports using 10BASE-T cables.

To connect a 10BASE-T cable, simply slot the connector into the relevant RJ-45 port. When the connector is fully in, its latch locks it into place. To disconnect the cable, push the connector’s latch in and remove it.

If you are using port 4 to connect to a workstation using a straight-through TP cable, ensure the Uplink/Normal switch is set to Normal (out).

The hub detects all port connections, so you can start using your network immediately. When you need more ports, simply add more OfficeConnect hubs.

Connecting Transceivers to the AUI Port

You can connect a 10Mbps Ethernet transceiver to your hub (Hub 4C only), using a standard AUI cable. Connect one end of the cable to the transceiver and the other end to the AUI port on the hub’s rear panel. This automatically disables the 10BASE-2 port, and activates the AUI/COAX LED to show the external transceiver is in use. Engage the slide locks at both ends of the AUI cable.

Connecting OfficeConnect Ethernet Hubs Together

You can increase the number of workstations that can connect to your network by adding more OfficeConnect hubs. You can use either 10BASE-T or 10BASE-2 (Hub 4C only) to do this.

Do not connect the same two hubs together using both 10BASE-T and 10BASE-2. This causes a network loop.

If you do not use the 10BASE-2 port, you do not need to connect a terminator (end piece) to it. If the AUI port is not used and a terminator is not connected to the 10BASE-2 port, the port partitions and the Coax Status LED lights yellow. This is correct operation.
