Section 4 - Troubleshooting

Symptom: Partition indicator lights up.

Causes: Hub has partitioned the 100BASE-TX (RJ-45) port due to excessive collisions.

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

Symptom: Link/Traffic indicator remains unlit.

Causes: The workstation’s network adapter, cable or the hub port is defective.

Solution: The most common cause is a defective network adapter or cable connection. Check the corresponding cable connections, or the workstation’s network adapter for possible defects. Verify that the correct cable type (straight or crossover) is being used. Replace the defective cable or adapter.

Symptom: Port 8 and Daisy-Chain port do not work simultaneously. Causes: Both ports are physically the same port.

Solution: Use either Port 8 or the Daisy-chain port.
