Making Network Connections

The 910H hub has eight RJ-45 connectors for attaching up to eight 10BASE-T based workstations. To establish such connections:

1.Ensure that both the Hub and the soon-to-be-connected workstation are in the power off mode.

2.Plug one end of the UTP cable into an available 10BASE-T hub port.

3.Plug the other end into the workstation’s network interface card. The following figure 3 illustrates a simple network topology using a 10BASE-T hub-to-workstation connections.

The 910H hub has one BNC port for making 10BASE2 hub-to-workstation connections. To establish such connections:

1.Ensure that both the Hub and the soon-to-be-connected workstation are in the power off mode.

2.Plug one end of the coaxial cable into the Hub’s BNC port. Please refer to figure 3 if you are having trouble locating this port.

3.Connect the other end of the coaxial cable to the workstation’s BNC connector located on the network interface card. Please refer to figure 3 for an illustration of such a connection.

Note: If port 1 (BNC PORT) doesn’t connect to the hub port1 (BNC PORT) is indicated by the alternate flashing of the green and yellow LEDs. The port 1 LEDs don’t flash after connecting cable to port 1 and using hub.

The following diagram illustrates 10BASET and 10BASE-2 network connections using the hubs BNC connector.
