Installing firmware
You can use either the web-based manager or the CLI to upgrade or downgrade the
firmware of the FortiMail unit.
Firmware changes are either:
• an upgrade to a newer version
• a reversion to an earlier version
The firmware version number is used to determine if you are upgrading or reverting your
firmware image.
For example, if your current firmware version is FortiMail-400
3.00,build288,080327, changing to FortiMail-400 3.00,build266,071209,
an earlier build number and date, indicates you are reverting.
To install firmware using the web-based manager
1 Log in to the Fortinet Technical Support web site, https://support.fortinet.com/.
2 Download the firmware image file to your management computer.
3 Log in to the web-based manager as the “admin” administrator, or an administrator
account whose domain is “system” and that has system configuration read and write
privileges.
4 In the advanced management mode, go to System > Status > Status.
If this menu option does not appear, first select Advanced >> to switch to the advanced
mode of the web-based manager.
5 In the System Information widget, in the Firmware Version row, select Update.
6 Select Browse to locate and select the firmware file that you want to install, then select
OK.
7 Select OK.
Your management computer uploads the firmware image to the FortiMail unit. The
FortiMail unit installs the firmware and restarts. Time required varies by the size of the
file and the speed of your network connection.
If you are downgrading the firmware to a previous version, the FortiMail unit reverts the
configuration to default values for that version of the firmware. You must either
reconfigure the FortiMail unit or restore the configuration file.
8 To verify that the firmware was successfully installed, log in to the web-based manager
and go to System > Status > Status. Text appearing in the Firmware Version row
indicates the currently installed firmware version.
To install firmware using the CLI
1 Log in to the Fortinet Technical Support web site, https://support.fortinet.com/.
2 Download the firmware image file to your management computer.
3 Connect your management computer to the FortiMail console port using a RJ-45-to-
DB-9 serial cable or a null-modem cable.
Caution: Back up your configuration before beginning this procedure.
Reverting to an earlier firmware version could reset the configuration, including the IP
addresses of network interfaces. For information on reconnecting to a FortiMail unit whose
network interface configuration has been reset, see “Connecting to the web-based
manager or CLI” on page 28.
