Troubleshooting Chart
Symptom Action
LED Indicators
Power LED is Off • External power supply has failed or is disconnected.
• Check connections between the CheetahAccess Wireless Gateway,
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 Accton Technical Support for
assistance.
