image. Once the backup firmware image is installed you can switch to this backup
image when required.

Installing a backup firmware image
To run 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 the FortiGate as described in
the procedure “Install a firmware image from a system reboot using the CLI” on
page 75.
To install a backup firmware image:
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 your TFTP server.
Note: The local IP address is only used to download the firmware image. After the firmware is
installed the address of this interface is changed back to the default IP address for this interface.
