Changing the FortiGate firmware System status
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 IP address of the TFTP server 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_ip>
Where <name_str> is the name of the firmware image file on the TFTP server and
<tftp_ip> is the IP address of the TFTP server. For example, if the firmware image
file name is FGT_300-v250-build045-FORTINET.out and the IP address of the
TFTP server is 192.168.1.168, enter:
execute restore image FGT_300-v250-build045-FORTINET.out
192.168.1.168
The FortiGate unit uploads the firmware image file, upgrades to the new firmware
version, and restarts. This process takes a few minutes.
