FortiGate 1000D -Reboots after 5 s

Hi All,

 

As this is my first post, first of all i would like to say loud Hello :) I became a happy administrator who has now a chance to configure fotigate 1000D. Unfortunately my adventure with FotiGate is starting with constatnt reboot and honestly i do not know what could be the cause. I was searching if someone had similar situation, but without success. Below output from console where appliance is stopping  and doing automatic reboot:
