image. Once the backup firmware image is installed you can switch to this backup
image when required.
This section describes:
• Installing a backup firmware image
• Switching to the backup firmware image
• Switching back to the default firmware image
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 “Installing firmware images from a system reboot using the CLI” on
page 107 .
Note: The local IP address is used only 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.
