OS9 login / shutdown

I've just come across my first OS9 system, and know absolutely nothing about OS9 other than that it's vaguely UNIX-like. Before I try hooking the hard disk up and seeing if it actually works, obvious questions follow: 1) I assume there's a login process. Of course I don't know any account details for the system; are there any tricks to breaking in as there often are with old UNIX systems? 2) Assuming I can't log in at this stage, is it possible to cleanly shut the system down? e.g. some magic keypress or login name (as there is with Apollo machines) 3) If I can login somehow, how do I then shut the system down properly? Is there a shutdown command in OS9, or is it something else entirely? On the plus side, the interface between host and disk unit is SASI, so there's a chance I can do a raw backup of the drive via a modern system. On the minus side, the physical drive is an ST506 type via an OMTI bridge board, so I can't easily go from raw backup to working system without proper low-level format utils (which I don't have, although I'm still sorting through floppies that came in the same haul) Of course all of this assumes that a) the hard drive isn't toast already and b) that the hard drive which came in the pile of stuff actually belongs with this system in the first place :) ta Jules
