Fortinet fortigate-200a Betriebsanweisung

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

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 
FGT_300-v280-build158-FORTINET.out and the IP address of the TFTP server 

is 192.168.1.168, enter:

execute restore image FGT_300-v280-build158-FORTINET.out 
192.168.1.168 
The FortiGate unit responds with the message:
This operation will replace the current firmware version!
Do you want to continue? (y/n)

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

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

Reconnect to the CLI.

To confirm that the new firmware image has been loaded, enter:
get system status

To restore your previous configuration if needed, use the command:
execute restore config <name_str> <tftp_ipv4>

Update antivirus and attack definitions. 
For information, see 

, or from 

the CLI, enter:
execute update_now

This procedure installs a specified 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 version.

Note: This procedure varies for different FortiGate BIOS versions. These variations are 
explained in the procedure steps that are affected. The version of the BIOS running on the 
FortiGate unit is displayed when you restart the FortiGate unit using the CLI through a console 
connection.
