Changing the FortiGate firmware System status
For this procedure you:
• access the CLI by connecting to the FortiGate console port using a null-modem
cable,
• install a TFTP server that you can connect to from port3. The TFTP server should
be on the same subnet as port3.
Before beginning this procedure you can:
• Back up the FortiGate unit configuration.
For information, see “Backing up and Restoring” on page 118 .
• Back up the IPS custom signatures.
For information, see “Backing up and restoring custom signature files” on
page 299 .
• Back up web content and email filtering lists.
For information, see “Web filter” on page 323 and “Spam filter” on page 337 .
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 port3 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)
