- I am having a puzzling problem with a uVAX-3 I recently purchased. The
- system is made of a BA123, KA650, (3)MS650, TQK50/TK50, 8 plane VCB02,
- VR290 and a Emulex QD32. When I first got the system the VCB02 worked
- but I had a problem with the TK50, so the system was never on for long
- but it was powered up and down servial times. After the TK50 problem
- was fixed I was formating the drives via the QD32 (takes a while) and
- the VCB02/VR290 stopped working. I had a RS232 console cable, and just
- unpluged the cable to the VR290, pluged in a VT220 and reformated the
- drives. A day or so later I went back to load software and the system
- would not come up, the CPU card stalled in selftest 3. I found that
- removing the VCB02 card set allowed me to boot the system, so I aranged
- a swap of the VCB02 card set. Same results with the new card set.
- I am stumped, what am I missing? I am 100% certain that the system
- booted more that once with the VCB02 card set still in the back plane
- the night it first failed. One more item, the original VCB02 card set
- checked out OK when it was returned. The party I got the system from
- thinks that the next step is swapping the VR290, but I can't see how a
- bad VR290 could cause the problem I am seeing.
