Hi All, my Fortigate 900D, After one power outage is not working any more, but power led is bright. When I plugged the console cable into the computer, it sent logs continuously without stopping. Could you please tell me what's wrong with this? handle it.
Thank you guys.

Hi @vndic 

Did you already tried to reformat the Fortigate?

If yes and your device still have valid support, I suggest to create ticket to Technical Support as this may need RMA.

Thank you,

Hi @adimailig ,

        I reboot the Fortigate and press M key to access configuration menu and try reformat boot disk,  TFTP image ( try 2 option: save, boot without save), but I alway get message:

Invaild port number 255
scsi_print_error[1150]scsi error

Because  license is expired so I can't create ticket to Technical Support 

Thank for your help
