19.6 Resetting the NWA/WAC

If you cannot access the NWA/WAC by any method, try restarting it by turning the power off and
then on again. If you still cannot access the NWA/WAC by any method or you forget the
administrator password(s), you can reset the NWA/WAC to its factory-default settings. Any
configuration files or shell scripts that you saved on the NWA/WAC should still be available
afterwards.

Use the following procedure to reset the NWA/WAC to its factory-default settings. This overwrites
the settings in the startup-config.conf file with the settings in the system-default.conf file.

Note: This procedure removes the current configuration.

1

Make sure the Power LED is on and not blinking.

2

Press the

RESET

button and hold it until the Power LED begins to blink. (This usually takes about

ten seconds.)

3

Release the

RESET

button, and wait for the NWA/WAC to restart.

You should be able to access the NWA/WAC using the default settings.
