Select BladeVPS at the top of the Control Panel and then select the VPS you want to restart on the left hand side. You will then see the console where you have the options to 'Stop' or 'Restart' your server.
Please note: 'Reset' has the meaning of a 'Restart'. It will restart your VPS but have no effect on the data on your VPS. The 'Stop'-button will change to 'Start' after using it. Using it will start the VPS again.
