"fiery" have right. If the server is stuck in Starting up it, means it not booting into ready state, so you certainly need to reinstall the Fiery system software from DVD's or from clone (if you have one).
Don't have DVD's
I see a 'mounted' E drive on the system named EFI
Not sure how to go along booting it
About how many DISK's would it be?
There are 3 DVD`s
