 Chapter 1 Introducing the ZyWALL

ZyWALL USG 1000 User’s Guide

Always use Maintenance > Shutdown > Shutdown or the 

shutdown 

command before you turn off the ZyWALL or remove the power. Not 
doing so can cause the firmware to become corrupt.  

The ZyWALL 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 3   Starting and Stopping the ZyWALL

Turning on the 
power

A cold start occurs when you turn on the power to the ZyWALL. The 
ZyWALL powers up, checks the hardware, and starts the system 
processes.

Rebooting the 
ZyWALL

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 ZyWALL 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, the ZyWALL sets the configuration 
to its default values and then reboots.

Clicking 
Maintenance > 
Shutdown > 
Shutdown or 
using the 

shutdown 

command

Clicking Maintenance > Shutdown > Shutdown or using the 

shutdown

 command writes all cached data to the local storage and 

stops the system processes. Wait for the device to shut down and 
then manually turn off or remove the power. It does not turn off the 
power. 

Disconnecting the 
power

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