APPENDIX A

TROUBLESHOOTING

This appendix describes common problems you may encounter

and possible solutions to them. The Barricade can be easily monitored through panel indicators to identify problems. If you cannot resolve any connection problems after checking the indicators, then refer to the other sections in the following table.

LED Indicators

 

 

 

Power LED is Off

• External power supply has failed or is

 

disconnected.

 

• Check connections between the Barricade, the

 

external power supply, and the wall outlet.

 

• 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

 

external 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, then the

 

external power supply may be defective. In this

 

case, contact SMC Technical Support for

 

assistance.
