Clean installing firmware
Clean installing the firmware can be useful if:
• you are unable to connect to the FortiVoice unit using the web-based manager or the CLI
• you want to install firmware without preserving any existing configuration
• a firmware version that you want to install requires that you format the boot device (see the
Release Notes accompanying the firmware)
Unlike upgrading or downgrading firmware, clean installing firmware re-images the boot device.
Also, a clean install can only be done during a boot interrupt, before network connectivity is
available, and therefore requires a local console connection to the CLI. A clean install cannot
be done through a network connection.
To clean install the firmware
1. Download the firmware file from the Fortinet Technical Support web site,
https://support.fortinet.com/.
2. Connect your management computer to the FortiVoice console port using an RJ-45 to DB-9
serial cable or a null-modem cable.
3. Initiate a local console connection from your management computer to the CLI of the
FortiVoice unit, and log in as the admin administrator, or an administrator account that has
system configuration read and write privileges.
4. Connect port1 of the FortiVoice unit directly to the same subnet as a TFTP server.
5. Copy the new firmware image file to the root directory of the TFTP server.
6. Verify that the TFTP server is currently running, and that the FortiVoice unit can reach the
TFTP server.
To use the FortiVoice CLI to verify connectivity, if it is responsive, enter the following
command:
execute ping 192.168.2.99
where 192.168.2.99 is the IP address of the TFTP server.
7. Enter the following command to restart the FortiVoice unit:
execute reboot
or power off and then power on the FortiVoice unit.
8. As the FortiVoice units starts, a series of system startup messages are displayed.
Press any key to display configuration menu........
Back up your configuration before beginning this procedure, if possible. A clean install resets
the configuration, including the IP addresses of network interfaces. For information on
backups, see “Backing up configuration” on page 96. For information on reconnecting to a
FortiVoice unit whose network interface configuration has been reset, see “Reconnecting to
the FortiVoice unit” on page 261.
If you are reverting to a previous FortiVoice version, you might not be able to restore your
previous configuration from the backup configuration file.
