4 Make 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
5 Enter 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> is the name of the firmware image file and <tftp_ip> is
the IP address of the TFTP server. For example, if the firmware image file name is
v2.80image.com and the IP address of the TFTP server is 192.168.1.168,
enter:
execute restore v2.80image.out 192.168.1.168
The FortiGate unit responds with the message:
This operation will replace the current firmware version!

The FortiGate unit uploads the firmware image file. After the file uploads, a
message similar to the following is displayed:
Get image from tftp server OK.
