Troubleshooting

Diagnosing Hub Indicators

The hub can be easily monitored through panel indicators to assist the network manager in identifying problems. This section describes common problems you may encounter and possible solutions.

Symptom: Power indicator does not light up (green) after power on.

Cause: Defective power outlet, power cord, or internal power supply.

Solution: Check the power outlet by plugging in another device that is functioning properly. Check the power cord with another device. If these measures fail to resolve the problem, have the unit's power supply replaced by a qualified Accton distributor.

Symptom: Link indicator does not light up (green) after making a connection.

Cause: Network interface (e.g., a network adapter card on the attached device), network cable, or 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 attached device. Check the adapter on the attached device and cable connections for possible defects. See if your cable is functioning properly by using it for another port and attached device that displays valid indications when connected to the network. Replace the defective adapter or cable if necessary. Also verify that you have not exceeded specified limits for any attached media as summarized in the following table:
