EtherHub-5st User’s Guide

Connect the hub to another hub in a daisy-chain configuration, if necessary. When daisy- chaining, use port 5MDI instead of station port 5MDI-X.

To limit the number of hubs in a path (when daisy-chaining more than two hubs), link several hubs to one central hub. And make sure there is only one path between any two stations on the network.

3. Plug the power cable into the hub, and connect it to an electrical outlet.

Troubleshooting

Symptom: Partition indicator lights up.

Causes:Hub has partitioned 10BASE-T (RJ-45) port.

Solution: If port partitioning has occurred, the hub will automatically enable the port when the faulty condition disappears.

Symptom: Link-RX indicator remains unlit.

Causes:Workstation’s network adapter, cable or hub port is defective.

Solution: The most common cause is a defective network adapter or cable connection. Check the corresponding cable connections, or theworkstation’s network adapter for possible defects. Verify that the correct cable type (straight or crossover) is being used. (Note that crossover cable is only required if you cascade hubs via the RJ-45 station ports; i.e., the Daisy-Chain port is not used.) Replace the defective cable or adapter.

Other Important Tips

1.Ensure that cable distances, repeater limits, and other physical aspects of the installation do not exceed IEEE 802.3 recommendations.

2.Verify the cabling type used is correct. Tighten all cable connections.

3.

Make sure the network adapter cards installed in the workstations and

cable connections are

 

in good working condition.

 

4.

Ascertain that your network is properly configured. Make sure that all

hubs are connected

to the network. Sometimes, hubs may be unintentionally disconnected from the network.

5.You cannot use RJ-45 station port 5MDI-X and the daisy-chain port 5MDI at the same time. Make sure that when you use the RJ-45 daisy-chain port, station port 5 is not connected to any node.
