Installing firmware

You can use either the web-based manager or the CLI to upgrade or downgrade the firmware of the FortiVoice Gateway.

Administrators whose access profile contains Read-Write access in the Others category, such as the admin administrator, can change the FortiVoice Gateway 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. To access the firmware version in the FortiVoice Gateway web-based manager, go to Dashboard > Status and the System Information widget. You can find the firmware version details in the Firmware version row. For example, if your current firmware version is v6.00,build189,200324, then changing to 6.00,build179,200218, an earlier build number and date, indicates that you are reverting.

Reverting to an earlier version may cause the FortiVoice Gateway 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.

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.

To install firmware using the web-based manager

Log in to the Fortinet Technical Support web site, https://support.fortinet.com/.
Download the firmware image file to your management computer.
Log in to the web-based manager as the admin administrator, or an administrator account that has system configuration read and write privileges.
Install firmware in one of two ways:
- Go to Dashboard > Status, and in the System Information widget, 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 Gateway. The FortiVoice Gateway 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 Gateway reverts the configuration to default values for that version of the firmware. You must either reconfigure the FortiVoice Gateway or restore the configuration file.
Clear the cache of your web browser and restart it to ensure that it reloads the web-based manager and correctly displays all changes.
To verify that the firmware was successfully installed, log in to the web UI and go to Dashboard > Status. Text appearing in the Firmware version row indicates the currently installed firmware version.

To install firmware using the CLI

Log in to the Fortinet Technical Support web site, https://support.fortinet.com/.
Download the firmware image file to your management computer.
Connect your management computer to the FortiVoice Gateway console port using an RJ-45 to DB-9 serial cable or a null-modem cable.
Initiate a connection from your management computer to the CLI of the FortiVoice Gateway, and log in as the admin administrator, or an administrator account that has system configuration read and write privileges.
Connect port1 of the FortiVoice Gateway directly or to the same subnet as a TFTP server.
Copy the new firmware image file to the root directory of the TFTP server.
Verify that the TFTP server is currently running, and that the FortiVoice Gateway can reach the TFTP server.
To use the FortiVoice Gateway CLI to verify connectivity, enter the following command:

execute ping 192.168.2.99

where 192.168.2.99 is the IP address of the TFTP server.
Enter the following command to download the firmware image from the TFTP server to the FortiVoice Gateway:
execute restore image tftp <name_str> <tftp_ipv4>

where <name_str> is the name of the firmware image file and <tftp_ipv4> is the IP address of the TFTP server. For example, if the firmware image file name is image.out and the IP address of the TFTP server is 192.168.2.99, enter:

execute restore image tftp image.out 192.168.2.99

One of the following messages appears:

This operation will replace the current firmware version!

Do you want to continue? (y/n)

or:

Get image from tftp server OK.

This operation will downgrade the current firmware version!

Do you want to continue? (y/n)
Type y.
The FortiVoice Gateway downloads the firmware image file from the TFTP server. The FortiVoice Gateway 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 Gateway reverts the configuration to default values for that version of the firmware. You must either reconfigure the FortiVoice Gateway or restore the configuration file.
If you also use the web-based manager, clear the cache of your web browser and restart it to ensure that it reloads the web-based manager and correctly displays all tab, button, and other changes.
To verify that the firmware was successfully installed, log in to the CLI and type:
get system status
If you have downgraded the firmware version, reconnect to the FortiVoice Gateway using its default IP address for port1, 192.168.1.99, and restore the configuration file. For details, see Reconnecting to the FortiVoice Gateway and Restoring the configuration.
If you have upgraded the firmware version, to verify the conversion of the configuration file, see Verifying the configuration. If the upgrade is unsuccessful, you can downgrade the firmware to a previous version.

Reconnecting to the FortiVoice Gateway

After downgrading to a previous firmware version, the FortiVoice Gateway reverts to default settings for the installed firmware version, including the IP addresses of network interfaces through which you connect to the FortiVoice Gateway web-based manager and/or CLI.

If your FortiVoice Gateway has not been reset to its default configuration, but you cannot connect to the web-based manager or CLI, you can restore the firmware, resetting the FortiVoice Gateway to its default configuration in order to reconnect using the default network interface IP address. For more information, see Performing a clean firmware installation.

To reconnect using the CLI

Connect your management computer to the FortiVoice Gateway console port using an RJ-45 to DB-9 serial cable or a null-modem cable.
Start HyperTerminal, enter a name for the connection and click OK.
Configure HyperTerminal to connect directly to the communications (COM) port on your computer and click OK.

Verifying the configuration

After installing a new firmware file, you should verify that the configuration has been successfully converted to the format required by the new firmware and that no configuration data has been lost.

In addition to verifying successful conversion, verifying the configuration also provides familiarity with new and changed features.

To verify the configuration upgrade

Clear your browser’s cache and refresh the login page of the web-based manager.
Log in to the web-based manager using the admin administrator account.
Other administrator accounts may not have sufficient privileges to completely review the configuration.
Review the configuration and compare it with your configuration backup to verify that the configuration has been correctly converted.

Upgrading

If you are upgrading, it is especially important to note that the upgrade process may require a specific path. Very old versions of the firmware may not be supported by the configuration upgrade scripts that are used by the newest firmware. As a result, you may need to upgrade to an intermediate version of the firmware first, before upgrading to your intended version. Upgrade paths are described in the Release Notes.

Before upgrading the firmware of the FortiVoice Gateway, for the most current upgrade information, review the Release Notes for the new firmware version. Release Notes are available from http://support.fortinet.com when downloading the firmware image file.

Release Notes may contain late-breaking information that was not available at the time this guide was prepared.
