1.7 Starting and Stopping the NWA/WAC
Here are some of the ways to start and stop the NWA/WAC.
Always use Maintenance > Shutdown or the
shutdown
command before
you turn off the NWA/WAC or remove the power. Not doing so can cause
the firmware to become corrupt.
The NWA/WAC does not stop or start the system processes when you apply configuration files or
run shell scripts although you may temporarily lose access to network resources.
