This section explains some of the ways to start and stop the ZyWALL. These are summarized below.

Table 3 Starting and Stopping the ZyWALL

METHOD

DESCRIPTION

Turning on the power button

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 disk, 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.

 

 

Using the shutdown command

The shutdown command writes all cached data to disk and

 

stops the system processes. It does not turn off the power.You

 

have to turn the power off and on manually to start the ZyWALL

 

again. You should use this command before you turn off the

 

ZyWALL.

 

 

Turning off the power button

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 disk.
