Please note that the device used in this tutorial is not connected to any production environment.
Firstly connect the cables properly. Refer this video
Cables used to connect to the console port and PC
Find the COM port first (this is the device manager in Win8.1)
In my case, I had to install the drivers for usb2.0-ser. [Download Drivers at: http://www.winchiphead.com/download/CH341/CH341SER.ZIP]
Connect using PuTTY
[Download PuTTY at: http://www.putty.org/ ]
If needed reboot the device (sometimes needed). Just give a power reset
Enter maintainer as the username. For the password bcpb + the serial number of the firewall (letters of the serial number are in UPPERCASE format)
enter exec factoryreset and press Y
CONGRATULATIONS…!! FortiGate Firewall is restored to the factory defaults configurations. Now you can login through preferred medium. In this case web browser is used.
