Troubleshooting Chart

Symptom	Action

LED Indicators

Power LED is	• Check connections between the Barricade, the
Off	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 Technical Support for assistance.
