Install a firmware image 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 to re-install the current firmware.

Note: There are a few variations on this procedure for different FortiGate BIOS versions. These variations are explained in the procedure steps that are affected. The version of the BIOS running on your FortiGate unit is displayed when you restart the FortiGate unit while accessing the CLI by connecting to the FortiGate console port using a null-modem cable.

To run 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 running this procedure you can:

•Backup the FortiGate unit configuration, use the procedure “Backing up system settings” on page 83.

•Backup the NIDS user defined signatures, see the FortiGate NIDS Guide

•Backup web content and email filtering lists, 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 may not be able to restore your previous configuration from the backup configuration file.

Note: Installing firmware replaces your current antivirus and attack definitions with the definitions included with the firmware release that you are installing. When you have installed new firmware, use the procedure “Manually updating antivirus and attack definitions” on page 95 to make sure that antivirus and attack definitions are up-to-date.
