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.

Use this procedure to install a new firmware version or revert to a previous firmware version. To use this procedure, you must connect to the CLI using the FortiGate console port and a RJ-45 to DB-9 or null-modem cable. This procedure reverts the FortiGate unit to its factory default configuration.

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 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

•back up the IPS custom signatures

•back up web content and email filtering lists

For information, see the FortiGate Administration Guide.

If you are reverting to a previous FortiOS version (for example, reverting from FortiOS v3.0 to FortiOS v2.80), 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, along with the definitions included with the firmware release you are installing. After you install new firmware, use the procedure make sure that antivirus and attack definitions are up to date. For information, see the FortiGate Administration Guide.
