Hi,
I'm posting to ask for a little help understanding what my Octane is trying to tell me.
When cold-booted, there is no boot tune, but fans are on, I get solid white from the lightbar, the hard disk doesn't spin up, and there is no graphics display. This seems to indicate an issue with the system board.
After 1 or 2 power resets it boots fine, and I can run the IDE, where the 'memory' test fails, indicating a failure on memory DIMMs.
My hope (and my wallet's) is that replacing a single component would solve the problems, like just the DIMMs or just the ip30 board. However I'm really wondering if the recent gfx board failure and now the memory, hd, and ip30 board are really trying to tell me I’ve got a failing PSU.
I'm a little unsure about what component to replace.
Thanks in advance for any helpful insight on where these problems might be stemming from!
Background:
Months ago I dug my Octane out of the corner to get it ready to sell. It's big, heavy, and in the way. Unfortunately as soon as I booted it up, that impulse disappeared, feelings were rekindled, and it felt once again like a keeper.
After about a month of use, the machine would panic: kernel fault, indicating ESSI problems. Indeed, onboard diags directed me to replace the ESSI (MOT20) board. Did that. No more panic and graphics were back to normal.
However, immediately after swapping gfx boards, the hard disk was not spinning up reliably, especially on cold boots. I have 2 identical 9gb drives (SGI IBM DDRS-39130W S95D), but only 1 installed at the moment. I swapped the drives to check if one was failing. No difference.
Further runs of the IDE would sometimes hang indefinitely, sometimes pass without problem. When the more in-depth 'memory' test is run, it fails every time. It finds a “
Failure detected on the MEMORY DIMMS.” When the DIMM positions are swapped, the same test would sometimes call out a specific DIMM in S1 or S2. It's a 2x256mb configuration. No problem ever running ip30, pm, frontplane tests as long as they were run before memory.
I reseated all boards, DIMMs, CPU, disassembled to inspect and clean the SCSI backplane, and disassembled to clean and inspect the psu. Nothing noticeably awry. No change.
Just last week I popped in a new lightbar (thanks weblacky!
) for another point of feedback. So now on cold boots: white light, no boot chime, fans on, no graphics, no hd spin up. With those symptoms, I think the flowchart for troubleshooting using the LEDs (Octane Owner's Guide) says the IP30 board needs to be replaced.
Here’s some hardware info. Please let me know if more info is needed.
