Rebooting your firewall
You can reboot the firewall in one of the following ways to recover from an error condition:
•
Reboot the firewall immediately at the command line interface (CLI).
•
At the CLI, schedule a reboot to occur at a specific time and date or after a delay.
•
Power off and then re-power on the firewall. This method, also known as hardware reboot or cold
reboot, might cause data loss, and is the least preferred method.
IMPORTANT:
•
Specify the boot file before you use the
reboot
command to reboot the firewall.
•
For data security, if you are performing file operations at the reboot time, the system does not reboot.
The precision of the rebooting timer is 1 minute. One minute before the rebooting time, the firewall
prompts "REBOOT IN ONE MINUTE" and reboots in one minute.
