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.

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.

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 internal 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. For information, see “Backing up system settings” on page 108.

•Back up the NIDS user defined signatures. For information, see the FortiGate NIDS Guide.

•Back up web content and email filtering lists. For information, 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.

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 119 to make sure that antivirus and attack definitions are up to date.
