Reset Fortigate 60E - without console cable

I wanted to change from software switch to hardware switch (so i can use seperate ports for eahc network) but had to disable software first which then made the router inaccessible.

So i go to my Fortigate box (always keep everything) and it must not of come with a console cable to reset it. Is there another way to reset it? Theres a reset button on the back but doesnt seem to work (tried reset after started up within first 30 seconds).
