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.
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 “Backing up and Restoring” on page 118.
• Back up the IPS custom signatures.
For information, see “Backing up and restoring custom signature files” on
page 299.
• Back up web content and email filtering lists.
For information, see “Web filter” on page 323 and “Spam filter” on page 337.
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.
