Hi jan-jaap, Thank you so much for the guidance!  This Crimson does have the silver PowerOne PSU. I had to replace it about 20 years ago and do remember it was a bit of work to get in there.  I've read through your PSU thread twice, excellent info thanks for sharing that. The second non-RE Crimson I have is the black Cherokee PSU, I'm not planning to turn it on now that you tell me it could eat itself, sad.

On the topic of RM boards, I've always tried to be careful inserting them.  That said, what about a putting a bit of Deoxit into the pin holes on the backplane connectors of the RM board to help lubricate when re-inserted?  I use this stuff on old PCs.

Ok, maybe don't mess with the RE boards, words of wisdom.  The card cage was the six fan model which i had pulled and cleaned when swapped the PSU, but I'll verify they are all spinning.

I have a good feeling about the OLS in the Onyx and Challenge.  SGI had replaced them for me with the updated units shortly before the company went away and those OLS don't have many hours. I'll keep an eye on VCAM.

I do have a good soldering station and volt meter and I solder on x86 components so I should be ok here.  I'll be careful with the Crimson and take my time, I know its valuable.

This is awkward though, I have misplaced the key for the Onyx and Challenge.  Does any know what model key it is or have a picture?  Maybe I can get the local locksmith to make one.  If anyone has spares, I'd be willing to buy one.

Thanks,
TriOx
