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.
