Installing firmware images from a system reboot using the CLI
This procedure installs a specified firmware image and resets the FortiGate unit to
default settings. You can use this procedure to upgrade to a new firmware version,
revert to an older firmware version, or re-install the current firmware version.
To perform 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 inter nal interface.
The TFTP server should be on the same subnet as the internal interface.
Before beginning this procedure you can:
• Back up the FortiGate unit configuration. Fo r information, see “Backing up system
settings” on page 64.
• Back up the NIDS user defined signatures. For information, see the FortiGate
NIDS Guide.
• Back up web content and email filtering lists. For infor mation, see the FortiGate
Content Protection Guide.
If you are reverting to a previous FortiOS version (for example, reverting from FortiOS
v2.50 to FortiOS v2.36) you might not be able to restore your previous configuration
from the backup configuration file.
To install firmware from a system reboot
1Connect to the CLI using the null-modem cable and FortiGate console port.
2Make sure that the TFTP server is running.
3Copy the new firmware image file to the root directory of the TFTP server.
4Make sure that the internal interface is connected to the same network as the TFTP
server.
5To confirm that the FortiGate 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, enter:
execute ping 192.168.1.168
Note: Installing firmware replaces the current antivirus and attack definitions with the definitions
included with the firmware release that you are installing. After you install new firmware, use the
procedure “Manually initiating antivirus and attack definitions updates” on page 75 to make sure
that antivirus and attack definitions are up to date.
