To change the firmware using the CLI
Use the following procedure to upgrade the FortiLog unit to a newer firmware version
or revert to a previous firmware version.
To use the following procedure you must have a TFTP server that the FortiLog unit
can connect to.
This procedure reverts your FortiLog unit to its factory default configuration and
deletes all configuration on the unit.
Back up the FortiLog unit configuration before beginning this procedure using the
command execute backup config.
1 Make sure that the TFTP server is running.
2 Copy the new firmware image file to the root directory of the TFTP server.
3 Log into the CLI as the admin administrative user.
4 Make sure the FortiLog 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:
execute ping 192.168.1.168
5 Enter the following command to copy the firmware image from the TFTP server to the
FortiLog unit:
execute restore image
Where is the name of the firmware image file on the TFTP server and
is the IP address of the TFTP server. For example, if the firmware image
file name is FortiLog_400-v120.out and the IP address of the TFTP server is
192.168.1.168, enter:
execute restore image FortiLog_400-v120.out 192.168.1.168
• If you upgrade the firmware, the FortiLog unit uploads the firmware image file,
upgrades to the new firmware version, resets the configuration, restarts, and
displays the FortiLog login. This process takes a few minutes.
• If you revert to a previous firmware version, the FortiLog unit uploads the firmware
image file, reverts to the old firmware version, resets the configuration, restarts,
and displays the FortiLog unit login. This process takes a few minutes.
6 Reconnect to the CLI.
7 To confirm that the new firmware image is successfully installed, enter:
get system status
8 Restore your previous configuration. Use the following command:
execute restore config
Installing firmware from a system reboot
