to identify problems. This section describes common problems you may

LED Indicators
PWR 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, or
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 your
distributor for assistance.
