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.
Table 14 Starting and Stopping the NWA/WAC
METHOD DESCRIPTION
Turning on the power A cold start occurs when you turn on the power to the NWA/WAC. The NWA/WAC
powers up, checks the hardware, and starts the system processes.
Rebooting the NWA/
WAC
A warm start (without powering down and powering up again) occurs when you use the
Reboot button in the Reboot screen or when you use the reboot command. The NWA/
WAC writes all cached data to the local storage, stops the system processes, and then
does a warm start.
Using the RESET button If you press the RESET button on the back of the NWA/WAC, the NWA/WAC sets the
configuration to its default values and then reboots. See Section 22.6 on page 212 for
more information.

Disconnecting the

Power off occurs when you turn off the power to the NWA/WAC. The NWA/WAC simply
turns off. It does not stop the system processes or write cached data to local storage.
