So is that the FireGL V8650? Should work on Solaris 10:

What's the LED status?

I had a look at the card and it has a Sun FRU 375-3290-01 sticker, so it should be a regular XVR-100 card.
   

If you mean the LEDs in the front display, there are no warnings for left or right doors.

I ordered a XVR-600 from the bay and will have a look when it arrives in a few days.

Since I live in Germany and electricity is at a premium, I try not to fire up the 3x2750W power house unnecessarily in diag mode, which takes at least 35min to complete :-)
My wife also seconds that strongly.

Do you know if there is a special slot reserved for graphic adapters?

btw, here is a picture, when I first got her...
