Table 3 Starting and Stopping the ZyWALL

METHOD DESCRIPTION

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.
