Ultra-80 will not boot.
I have an Ultra-80 with 4CPUs, 1GB RAM and an Elite graphics card. When I power the system up the keyboard lights flash once, then the caps lock gives four short flashes, three long flashes and then three short flashes again. There is no video output. There is no O/S but a single 38Gig drive.
Am I correct in assuming that this flashing sequence is a form of debug? I do not have access to a serial terminal so will try and debug using the Sun display for the time being.
The memory is in two pairs of 256MB DIMS. One pair on the riser card and one pair on the main board.
1. Is the memory placement correct (this is a new system and I have never booted it before).
2. If I take it down to a single CPU which is the primary processor slot?
3. What does the flashing mean?
Any help would be very much appreciated. I would like to get this working before the wife finds out how much it cost !!!!!

Did you populate the memory yourself? bank 0 is
Riser board
U0301
U0302
system board
U1301
U1302
These systems can be a real pain in the but. Make sure the riser board is tightened down, finger tighter is fine.
Try powering off the unit, hold down stop-N at the same time and while holding it down power on the unit. Keep holding the stop and N keys for about 15 + seconds.
Keep me posted

I know very few people who can actually fasten down a screw/bolt/nut to factory torque settings by hand... it's impossible! How many blown gaskets before someone invented the torque wrench? The same can be said for the ideoligy behind Sun factory implementing torque settings for CPUs and memory riser boards. I would advise anyone who is maintaining Sun SPARC systems, old or new, to follow the instructions in the system service manual, to ignore these instructions is nonsense.

All is working now. The box was shipped very well packed but I guess something worked loose. I stripped the system down to bare boards and put it all back together again (torque tool ?).
Everything now works and I understand that this is a common problem with these systems (and the Ultra 60s).
Thanks for your suggestions. I would have replied sooner but my ISP connection became challanged.....
BTW a quad CPU Ultra-80 is a very nice system. I also have a SunPCI II card and this runs games that I have struggled with on ordinary pc's. All in all a nice, powerful and quiet system :-)

Harold, give us a break will you? Sun describe this item as a 'torque tool' so when you turn the memory riser fasteners using the 'torque tool' and the gap closes, this indicates that the screw has reached n pounds per square inch. So the bottom line is this, the engineers at Sun wanted to ensure that any engineers maintaining these systems could have a handy tool that would set the memory riser fasteners to a reasonably precise torque setting and the little tool does just that. I have a couple of snap-on torque wrenches I use on my motorcycles, I bought them way back in 1988 from a local snap-on dealer for about 1000USD, given the price and weight of these items they are not suitable for use with computer systems ( just imagine if you dropped it on a CPU memory board, it would be destroyed ). Furthermore the Sun documentation was written as a guidline for systems administrators, people carrying out professional maintenance on Sun systems, someone in such a position who may choose to ignore the factory recommended maintenance instructions would look rater foolish requesting funds to pay for a component that was damaged by their neglagance.
