It is recommended you use the shutdown command before turning off the 
ZyWALL.
When you apply configuration files or running shell scripts, the ZyWALL does not stop or 
start the system processes. However, you might lose access to network resources temporarily 
while the ZyWALL is applying configuration files or running shell scripts.
