Diagnosing Hub Indicators
This Fast EtherHub can be easily monitored through its comprehensive panel indicators. These indicators assist the network manager in identifying problems the hub may encounter. This section describes common problems you may encounter and possible solutions.
Symptom: Power indicator does not light up.
Cause: Defective power outlet, power cord, or internal power supply.
Solution: Have your unit’s power supply or Power LED replaced. Ask for dealer assistance.
Symptom: Partition indicator lights up.
Cause: Hub has partitioned a port.
Solution: If port partitioning has occurred, the hub will automatically enable the port when the faulty condition disappears.
Symptom: Link/Traffic indicator remains unlit after making a connection.
Cause: Workstation’s network adapter, the cable, or the hub port is defective.
Solution: Verify that the hub and attached device are powered on. Be sure the cable is plugged into both the hub and corresponding device. Verify that the proper cable type is used (Chapter 2), and that its length does not exceed 100 meters. Check the adapter on the attached device and cable connections for possible defects. Replace the defective adapter or cable if necessary
Use the diagnostic procedures described in the following section to verify that all other system components are functioning properly. If you still cannot resolve the problem, contact your Accton distributor for assistance.
