I have an R900 that had a motherboard fail from a bad surge. Received a replacement motherboard but there is no video output from the front or rear DSUB-15. I have a DRAC5 installed, and there is no video/console output there either. Unit powers on, all fans spin up, front display is blue with no errors. I suspect a DOA board. Could both PSU's be bad also? When powered on both PSU's have 2 green lights. I have powered the board on with a single CPU and single memory riser (and alternated between CPUs and risers) still no video output. If video is disable in BIOS, would that stop the DRAC5 from displaying console output?
Also, the model board I have and the replacement is the X947H, I see alot of RV9C7 boards as well, i suspect the are interchangeable but what is the difference?
Thanks,
