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.
