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 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 corresponding device. Verify that
the proper cable type is used and its length does not exceed specified
limits. Check the adapter on the attached device and cable connections
for possible defects. Replace the defective adapter or cable if necessary.
