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: 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 8 for further information.

If you are using port 16 to connect a workstation, ensure the Uplink/Normal switch is set to Normal (out).

TP cables are very easy to use. To connect a cable, simply slot the connector into the appropriate RJ-45 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.

Connecting Another OfficeConnect Hub

You may wish to connect another OfficeConnect hub to your Dual Speed Hub 16. Alternatively, you may wish to add your Hub to an existing 10Mbps network. When extending your network, you should be aware of the configuration rules given below.

If you connect two Dual Speed Hub 16 units directly together, the link between them operates at 100Mbps.

Fast Ethernet (100Mbps) Configuration Rules

The Dual Speed Hub 16 is a Class II hub. You can connect directly two Class II Fast Ethernet hubs (Class I Fast Ethernet hubs cannot be connected directly to other Fast Ethernet hubs). The total length of cable (A + B + C) between two workstations, or between a workstation and a non-repeater piece of equipment (such as a switch), must not exceed 205m (672ft). Each cable (A, B, or C) must not exceed 100m (328ft).
