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.
Note: This procedure varies for different FortiGate BIOS versions. These variations are
explained in the procedure steps that are affected. The version of the BIOS running on the
FortiGate unit is displayed when you restart the FortiGate unit using the CLI through a console
connection.
For 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 port1. The TFTP server should
be on the same subnet as port1.
Before beginning this procedure you can:
• Back up the FortiGate unit configuration.
For information, see
• Back up the IPS custom signatures.
For information, see
page 283.
• Back up web content and email filtering lists.
For information, see
If you are reverting to a previous FortiOS version (for example, reverting from FortiOS
v2.80 to FortiOS v2.50), you might not be able to restore your previous configuration
from the backup configuration file.
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 "To update antivirus and attack definitions" on page 120
and attack definitions are up to date.
