Changing the FortiGate firmware System status
If you are reverting to a previous FortiOS version (for example, reverting from FortiOS
v2.80 to FortiOS v2.50), you might not be able to restore your previous configuration
from the backup configuration file.
To install firmware from a system reboot
1 Connect to the CLI using the null-modem cable and FortiGate console port.
2 Make sure that the TFTP server is running.
3 Copy the new firmware image file to the root directory of the TFTP server.
4 Make sure that the internal interface is connected to the same network as the TFTP
server.
5 To confirm that the FortiGate unit can connect to the TFTP server, use the following
command to ping the computer running the TFTP server. For example, if the IP
address of the TFTP server is 192.168.1.168, enter:
execute ping 192.168.1.168
6 Enter the following command to restart the FortiGate unit:
execute reboot
The FortiGate unit responds with the following message:
This operation will reboot the system !
Do you want to continue? (y/n)

As the FortiGate units starts, a series of system startup messages is displayed.
When one of the following messages appears:

Press any key to display configuration menu.....

Immediately press any key to interrupt the system startup.
Note: Installing firmware replaces the current antivirus and attack definitions with the definitions
included with the firmware release that you are installing. After you install new firmware, use the
procedure
“To update antivirus and attack definitions” on page 121 to make sure that antivirus
and attack definitions are up to date.
Note: You have only 3 seconds to press any key. If you do not press a key soon enough, the
FortiGate unit reboots and you must log in and repeat the
execute reboot
command.
