Appendix A. Troubleshooting 

 

Diagnosing Switch Indicators 

 

The Power Led Is Off 

 

Make sure the AC power cord is connected to the switch and power source 
properly. 

 

Make sure the power source is ON. 

 

The Link/Act Led Is Off When A Device Is Connected To The 

Corresponding Port 

 

Make sure that the cable connectors are firmly plugged into the switch and 
the device. 

 

Make sure the connected device is turned on and working properly. 

 

The cable must be less than 100 meters long (328 feet). 

 

Check the port on the attached device and cable connections for possible 

 

defects. Replace the defective 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. If you still cannot isolate 
the problem, the internal power supply may be defective.
