Appendix A: Troubleshooting

Diagnosing Switch Indicators

 

Table A-1 Troubleshooting Chart

Symptom

Action

 

 

Power LED is Off

• Check connections between the switch, the power cord, and the wall

 

outlet.

 

• Contact your dealer for assistance.

 

• Contact SMC Technical Support.

 

 

Power LED is Amber

• Internal power supply has failed. Contact your local dealer for

 

assistance.

 

 

Link LED is Off

• 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.

 

 

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. 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 unit are unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.
