Make sure the FortiGate unit can connect to the TFTP server.
You can use the following command to ping the computer running the TFTP
server. For example, if the TFTP server's IP address is 192.168.1.168:
execute ping 192.168.1.168
Enter the following command to copy the firmware image from the TFTP server to
the FortiGate unit:
execute restore image <name_str> <tftp_ipv4>
Where <name_str> is the name of the firmware image file and <tftp_ip> is
the IP address of the TFTP server. For example, if the firmware image file name is
v2.80image.com and the IP address of the TFTP server is 192.168.1.168,
enter:
execute restore v2.80image.out 192.168.1.168
The FortiGate unit responds with the message:
This operation will replace the current firmware version!
Do you want to continue? (y/n)
Type y.
The FortiGate unit uploads the firmware image file. After the file uploads, a
message similar to the following is displayed:
Get image from tftp server OK.
Check image OK.
This operation will downgrade the current firmware version!
Do you want to continue? (y/n)
Type y.
The FortiGate unit reverts to the old firmware version, resets the configuration to
factory defaults, and restarts. This process takes a few minutes.
Reconnect to the CLI.
To confirm the new firmware image has been loaded, enter:
get system status
To restore your previous configuration, if needed, use the command:
execute restore config <name_str> <tftp_ipv4>
Update antivirus and attack definitions.
