Updating the firmware
Fortinet periodically releases FortiMail firmware updates to include enhancements and
address issues. After you have registered your FortiMail unit, FortiMail firmware is
available for download at
http://support.fortinet.com .
Installing new firmware can introduce new features and overwrites antivirus and antispam
packages using the versions of the packages that were current at the time that the
firmware image was built. To avoid repeat configuration and updates, update the firmware
before configuring the FortiMail unit and/or updating your FortiGuard Antivirus and
FortiGuard Antispam packages.
For late-breaking information specific to the firmware release version, see the Release
Notes available with that release.
This chapter includes the following topics:
•
Testing new firmware before installing it
• Installing firmware
• Installing backup firmware
• Restoring firmware
Testing new firmware before installing it
You can test a new firmware image by temporarily running it from memory, without saving
it to disk. By keeping your existing firmware on disk, if the evaluation fails, you do not have
to re-install your previous firmware. Instead, you can quickly revert to your existing
firmware by simply rebooting the FortiMail unit.
To test a new firmware image
1 Connect your management computer to the FortiMail console port using a RJ-45-to-
DB-9 serial cable or a null-modem cable.
2 Initiate a connection from your management computer to the CLI of the FortiMail unit.
For details, see
“Connecting to the CLI” on page 29 .
3 Connect port1 of the FortiMail unit directly or to the same subnet as a TFTP server.
4 Copy the new firmware image file to the root directory of the TFTP server.
5 Verify that the TFTP server is currently running, and that the FortiMail unit can reach
the TFTP server.
To use the FortiMail CLI to verify connectivity, enter the following command:
execute ping 192.168.1.168
where
192.168.1.168
is the IP address of the TFTP server.
Note: In addition to major releases that contain new features, Fortinet releases patch
releases that resolve specific issues without containing new features and/or changes to
existing features. It is recommended to download and install patch releases as soon as
they are available.
