Troubleshooting
4.1 Diagnosing Switch Indicators
The switch 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 |
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 switch port may be defective. |
Solution |
Verify that the switch and attached device are powered on. Be sure the cable is plugged into both the switch 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. |
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 PLANET distributor. |
4.2 Power and Cooling Problems
If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the side of the unit are unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, contact your PLANET distributor for assistance.
Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (e.g., the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.
