1 Overview

1.1 This subsection tells you how to connect a 10BASE2 thin UTP network to the Office Connect device so that users on the UTP network can communicate with the new network.

You can connect a 10BASE2 coaxial network to these Office Connect devices:

1.2 If you want to connect a 10BASE5 thick coaxial network to the new network, you must use an OfficeConnect Ethernet Hub 4C and an appropriate transceiver. Contact your supplier for more information about transceivers.

2 Connecting the coaxial network

2.1 To connect a 10BASE2 UTP network to an Office Connect device (Ethernet Hub 4C, Hub 8C, Hub 16C or 8/TPM):

Ensure that the coaxial segment has a free T-piece, or Y-piece, that is unused:

2.2 Connect the T-piece, or Y-piece, to the UTP port on the Office Connect device and twist the end of the T-piece to lock it in place.

Ensure that you do not accidentally disconnect the other connections to the T-piece.

The UTP LED on the device should be unlit to indicate that the equipment is connected correctly:

• If the UTP LED is unlit, the connection is OK and the users of the UTP  network can now communicate with the users of the new network.
• If the UTP LED is lit, the Coaxial port has been disabled. This usually indicates an incorrectly fitted coaxial cable or a badly terminated coaxial segment. It can also indicate a network loop, which occurs when a piece of equipment has more than one path through the network to the same device.

   

2.3 The AUI and UTP ports on the Office Connect Ethernet Hub 4C cannot be used simultaneously. If both ports have a connection, the AUI port is used and the Coaxial port is disabled.

So when using the Coaxial port on the Office Connect Ethernet Hub 4C, ensure that the AUI port does not have equipment connected to it. You can tell when the Coaxial port is in use: the left-hand LED of the AUI/UTP LED pair is unlit.
