Hi there!

This is my very first post so maybe I shall introduce myself first...
I may say I caught the "SGI virus" few months back when I decided to learn Unix and found no better way but to buy an O2 to help me on my quest (no one can deny it's way more classy to learn on an O2 rather than on a VM ). To have an SGI machine was an old dream of mine anyway and God only knows why it took me so long before making up my mind.
Well, thanks to Ian who (expertly!) prepared one machine for me, this old dream became true.

Since, time have past and I had the opportunity to acquire an Onyx2 Rackmount  (the leap with the O2 was huge!)
The price was fair, the specs were OK, the skins almost new and no sign of rust at all. So this was a pretty fair deal!
Of course, the "tricky" part is that the graphics module doesn't start at all. Therefore my post!

I am looking for advice so as to minimize the risk to mess up what is still working inside the rack and identify which board/part may be faulty.

At first, I was thinking of removing all boards of the rack so as to test the PSU/midplane/MSC only. I am pretty sure the graphics PSU is OK (despite I cannot be 100% sure but it delivers the correct voltage when tested apart).
Therefore my question: is there any minimum configuration (in terms of boards installed) inside the graphics module for it to able to start?
Another question: according to your personal experience, do you have any "best practice" or something else I could apply to identify the faulty parts?


Thanks in advance for your lights!

PS: I can post later the hw inventory of the "beast" if you want...
