Page 262 onwards kind of thing.
There are a bunch of diagnostic lights under the front cover too - but I couldn't find where it explains what those mean - might be worth looking into as well.
Aha - found the explanation:
Code:
Meaning of the seven green LEDs that are behind the frontpanel.
Perhaps you have seen the seven small holes near the undocumented connector on the front of your Octane. These are link status lights and show which ports of the Crossbar have items connected to.
BaseIO X
QA X X PCI Expansion
QD X X QB
QC X X Heart
My Octane has *only* QA (V6) and Heart LEDs lit. The rest is off. At
https://wiki.preterhuman.net/SGI_Octane#Troubleshooting
it states both BaseIO and Heart are always lit. :dodgy:
What is BaseIO?
After having reseated the system module, the LEDs changed to BaseIO AND Heart On, the rest is off now. Don't know if this means my V6 is not usable right now. :s
What I have tried so far:
* reseated the system module with and w/o DIMMS multiple times -
NOK
* swapping memory and CPU with other known to work models (double checked in a working Octane) -
NOK
* powering on only with memory, no CPU -
NOK
* powering on only with CPU, no memory -
NOK
* powering on with no CPU and no memory -
NOK
* all of the above with keyboard + mouse + vga (all three working and having been used earlier with the same machine) -
NOK
* all of the above with only power cable and null modem cable connected to port 1 -
NOK
NOK means I still have the original symptoms:
* Machine only powers on when power cable is plugged in.
* It won't react to the power button, reset button, nor NMI button.
* Both fans on the rear spin (upper one and PSU).
* HDD is read and spins on power on (when power cable is plugged in).
* No video output
* No console output
* Lightbar is always off
* Frontside status LEDs lit: BaseIO and Heart
Good. Ahm... I bought another Octane to do some of the above checks and thought it was a good idea to also swap the other way: take the CPU (400MHz) + RAM (1.5GB) from the failing Octane and try them in this new Octane (250MHz + 128MB IIRC).
This happened:
The new system immediately displayed the typical screens but the lightbar started flashing in red color. It then loaded IRIX fine and I could login as usual. I looked up what flashing red in the lightbar meant and it was a memory failure. I checked using hinv and in fact only 1GB of the 1.5GB were recognized. Some minutes later the same happened as with the other Octane: The system completely freezes and doesn't respond to anything. No power, reset or NMI button, no keybard, no mouse, nothing. I had to unplug it and now every time I plug it in again, I have exactly the same symptoms as with the other machine! So, my dear SGI enthusiasts, I now have two unusable machines with exactly the same problems. :-/
Ok, I started looking at the system module of the first Octane and have seen
4 different spots with jumpers, labeled:
1.
Chassis GND Jumper (
top and
side)
2.
Enable Passwd (
top and
side)
3.
NIC (
top and
side)
4.
Select Flash PROM (
top and
side)
My question to the pros here: Can/Should I do something using any of these jumpers? And how do I use them?
Any help is very much appreciated.
