Installing firmware images from a system reboot using the CLI System status
10 Type an IP address that the FortiGate unit can use to connect to the TFTP server.
The IP address can be any IP address that is valid for the network that the interface is
connected to. Make sure you do not enter the IP address of another device on this
network.
The following message appears:
Enter File Name [image.out]:
11 Enter the firmware image filename and press Enter.
The TFTP server uploads the firmware image file to the FortiGate unit and messages
similar to the following are displayed:
• FortiGate unit running v2.x BIOS
Do You Want To Save The Image? [Y/n]
Type Y.
• FortiGate unit running v3.x BIOS
Save as Default firmware/Run image without saving:[D/R]
or
Save as Default firmware/Backup firmware/Run image without
saving:[D/B/R]
12 Type D.
The FortiGate unit installs the new firmware image and restarts. The installation might
take a few minutes to complete.
Restoring the previous configuration
Change the internal interface address if required. You can do this from the CLI using
the command:
config system interface
edit internal
set ip <address_ipv4mask>
set allowaccess {ping https ssh telnet http}
end
After changing the interface address, you can access the FortiGate unit from the
web-based manager and restore the configuration.

configuration from the backup up configuration file.
