Netgear DC112A – AirCard Smart Cradle 사용자 설명서

You can use the LEDs to help identify the cause of problems and troubleshoot.

After you turn on power to the cradle, verify that the following sequence of events occurs:

When power is first applied, verify that the Power LED 

 is lit.

After approximately 30 seconds, verify the following:

The Power LED is solid green.

The Internet LED is lit.

The WiFi LED is lit unless you turned off the wireless radio.

You can use the LEDs on the front panel of the cradle for troubleshooting.

Make sure that the power adapter is securely connected to your cradle and securely 
connected to a working power outlet. 

Check that you are using the power adapter that NETGEAR supplied for this product.

If the Power LED blinks slowly and continuously, the cradle firmware is corrupted. This can 
happen if a firmware upgrade is interrupted, or if the cradle detects a problem with the 
firmware. If the error persists, a hardware problem occurred. 

When the cradle is turned on, the Power LED turns amber for about 20 seconds and then 
turns green. If the LED does not turn green, a problem occurred in cradle.

If the Power LED is still amber one minute after you turn on power to the cradle, do the 
following:

Turn off the power and then turn it back on to see if the cradle recovers.

Press and hold the Reset button to return the cradle to its factory settings. 

See 

154.

If the error persists, it is possible that a hardware problem occurred.

When the cradle is turned on, the LEDs light for about 10 seconds and then turn off. If all the 
LEDs stay on, this indicates a fault within the cradle.
