Installing firmware
You can use either the web-based manager or the CLI to upgrade or downgrade the firmware of
the FortiVoice unit.
Administrators whose access profile contains Read-Write access in the Others category, such
as the admin administrator, can change the FortiVoice firmware.
Firmware changes are either:
• an upgrade to a newer version
• a reversion to an earlier version
To determine if you are upgrading or reverting your firmware image, examine the firmware
version number. For example, if your current firmware version is FortiVoice-200D
2.00,build0082,120827, changing to FortiVoice-200D 2.00,build0081,120801, an
earlier build number and date, indicates that you are reverting.
Reverting to an earlier version may cause the FortiVoice unit to remove parts of the
configuration that are not valid for that earlier version. In some cases, you may lose all call data
and configurations.
When upgrading, there may also be additional considerations. For details, see “Upgrading” on
page 263.
Therefore, no matter if you are upgrading or downgrading, it is always a good practice to back
up the configuration and call data. For details, see “Backing up configuration” on page 96.
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 manger as the admin administrator, or an administrator account
that has system configuration read and write privileges.
4. Install firmware in one of two ways:
• Go to Monitor > System Status > Status, and in the System Information area, in the
Firmware version row, click Update. Click Browse to locate the firmware and then click
Upload.
• Go to System > Maintenance > Configuration, under Restore Firmware, click Browse to
locate the firmware. Then click Restore.
Your web browser uploads the firmware file to the FortiVoice unit. The FortiVoice 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 FortiVoice unit reverts the
configuration to default values for that version of the firmware. You must either reconfigure
the FortiVoice unit or restore the configuration file.
5. Clear the cache of your web browser and restart it to ensure that it reloads the web-based
manager and correctly displays all changes.
6. To verify that the firmware was successfully installed, log in to the web UI and go to
Monitor > 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.
