Installing firmware from a system reboot using the CLI

FortiGate Firmware

4Make sure the FortiGate unit can connect to the TFTP server.

You can use the following command to ping the computer running the TFTP server. For example, if the TFTP server’s IP address is 192.168.1.168:

execute ping 192.168.1.168

5Enter the following command to copy the firmware image from the TFTP server to the FortiGate unit:

execute restore image <name_str> <tftp_ipv4>

Where <name_str> the IP address of the imagev28.out and

is the name of the firmware image file and <tftp_ip4> is TFTP server. For example, if the firmware image file name is the IP address of the TFTP server is 192.168.1.168, enter:

execute restore image image28.out 192.168.1.168

The ForitGate unit responds with this message:

This operation will replace the current firmware version!

Do you want to continue? (y/n)

6Type y.

The FortiGate unit uploads the firmware image file. After the file uploads, a message similar to the following appears:

Get image from tftp server OK. Check image OK.

This operation will downgrade the current firmware version! Do you want to continue? (y/n)

7Type y.

The FortiGate unit reverts to the old firmware version, resets the configuration to factory defaults, and restarts. This process takes a few minutes.

8Reconnect to the CLI.

9To restore your previous configuration, if needed, use the command:

execute restore config <name_str> <tftp_ip4>

10Update antivirus and attack definitions using the command: execute update-now.

Installing firmware from a system reboot using the CLI

This procedure installs a firmware image and resets the FortiGate unit to default settings. You can use this procedure to upgrade to a new firmware version, revert to an older firmware version, or re-install the current firmware.

To use this procedure, you must connect to the CLI using the FortiGate console port and a RJ-45 to DB-9, or null modem cable.

This procedure reverts the FortiGate unit to its factory default configuration.

For this procedure you install a TFTP server that you can connect to from the FortiGate internal interface. The TFTP server should be on the same subnet as the internal interface.

Before beginning this procedure, it is recommended that you back up the FortiGate unit configuration.
