Okay, I bought a case, it's a little ugly, but it might work. I don't really know if it will, we'll see when I get it I guess. It's ground shipping, so it might take a week to show up. I'm not sure I want to tell you which case I bought at this point (it's not SGI or Apple, it's some crappy PC case maker) so you'll just have to wait for the pictures

If this doesn't work, I'll just build a pc out of this case or resell it, no big deal. The fuel was all taken apart, and parts were cleaned up.

This case I just bought is just experimental, if it works, I'll try to find some better looking one, we'll see. This is quite fun anyway. This case is certainly not as good looking as some SGI product, but that's not my primary concern at this point, it's a part of a much bigger project.

While I will be waiting for this new case, I plan to study the cooling part. I intend to replace the original heatsinks, I have not yet decided if this will go water cooling or air cooling. One think I've considered is that the original Fuel PDU is 450W, I may try to replace it with something else; I will as well study the pinout.

The Fuel has, supposedly, an ATX MOB (not quite?) ... but you'll need to get the hacksaw out to accommodate the graphics card? The Fuel puts the graphics at the bottom of the case, it's not part of the AGP/PCI/PCI-Express card cage area ...

I'm guessing your budget is small but have you considered a custom case? We built a custom rack mount case for a customer and the tooling and sheet metal charges were only a few thousand; the Engineering time was a lot more $$$

. The injection molding is another story ... $$$

I've considered the graphics card, and I believe it might just work, some chassis work might be required but I'm confident this could be a "go". We'll know as soon as I receive the case. I've measured the mobo and this might just work.

I intend not to spend more than a few hundreds on this deal, simply because there's no need for it, it either works or it doesn't. If I was going to follow the custom case road (I thought about it) I'd rather go buy a Tezro or Origin 2k/Onyx^2. And quite honestly, a 600Mhz Octane2 is roughly $600, therefore, therefore why would I spend more than a few hundred bucks on a Fuel mod?

This is entirely an "amateur" case mod, don't expect anything shiny, but I intend to try, and I believe this is the most important thing. Also, and that's an important thing (at least for me) I bought a large case to reduce the overall noise, I intend to chose the fans carefully in that regard. I've also considered server cases, but I've decided not to go this way either as most of them are usually very noisy.

I've always considered that the original Fuel case was of mediocre quality, especially compared to the Octane 2. In that regard I do like the Octane 2 better than the fuel, unfortunately, the Octane 2 has limited number of drives and/or no possibility to handle a SATA drive and a CD/DVD reader, which is a showstopper to my project. The number of Octane 2 pci slots is also limited to 3 (4 for the Fuel), while this is not a major concern, this is a little plus.

I certainly hope that the case I've just bought will do the job, I would imagine I will receive it in about a week from today, which gives me enough time to think about the cooling part and other things.

Keep the environmental monitoring of the L1 controller in mind here..

You'll have to resemble the original cooling quite precisely (i.e. 6 fans with certain minimum rpm - see the list in the fuel hardware aggregator thread: http://forums.nekochan.net/viewtopic.php?f=3&t=9046 ) or you'll have to disable the monitoring if you want the machine to stay powered on for longer than 60 seconds ;-)

I thought about this, I'm studying hard the cooling part now. Water cooling is not excluded, but I think I might simply replace the heatsinks with something with more punch.

Hi there,

Does anyone need a Sgi Fuel Case ?
I have two or three empty cases with front Bezel available for sale.

I'm afraid the shipping costs themselves would be higher than buying a used fuel here, in the US. But thanks for the offer, I just bought a 500Mhz fuel with a v10, 1GB ram, 18GB HD on craigslist for $100; not the best deal in the world considering it's "only" a 500Mhz but I needed some parts for my fuel surgery.

Yesterday I went to another Nekochan member to test the Fuel motherboard.
He has a working Fuel that's why.
So I connected his PSU to the motherboard only (no CPU or memory) and we connected a PC running hyperterm via a serial nullmodem cable to the internal L1 connector.

However only a few characters came out but we were not able to get the PSU running anyway (most likely we used the wrong switch as we learned). Anyway, we then assembled his Fuel again and connected that Fuel internal L1 to the PC but also there was no usefull output visible. 19200/8/1/no we used all the time.
Then we deceided to use the serial on the back of the Fuel and finally we got output running at 9600/8/1/no. That gave good output on the terminal.
But using these settings on the interal L1 did not work either.

Does anyone have any idea what cable, serial settings and terminal settings the L1 controller needs, both the internal and external connector?

This is indeed a really good find, the L1 would be super useful for the application I'm looking to port or simply to use the Fuel as a server.
I've never really looked at it, but I assume L1 gives you temperatures and allows you to bounce/stop/start the fuel, correct?

Correct.

Hooking a null modem serial cable 8N1 speed is 38400 for Origin if i recall, 9600 for some other SGI systems.
You should get a text menu or a login: prompt.
Hitting Control and T, should get you into L1.
There should be a command set on techpubs.sgi.com for L1..
I type help and figure out the commands from there for my L1 and L2.
From memory, stuff I have typed lately in L1 include "env" and "power down" to show environment settings and I recall fan speeds and temperatures... Sorry I hope this makes sense... really really tired..

Hope this helps,

Most importantly, can we power up the machine thru L1? (yes this involves that L1 is active all the time). It's my understanding that L1 is available even in the case that the machine is down, correct?

Thanks,

Yes, the L1 command "power up" will bring the system online (same as hitting the front power button). The L1 becomes active as soon as you plug the Fuel into a power outlet (it's always on).

That is very good news Neko!
But do you know how to access the L1 from the Fuel, and what serial settings + cable are needed?

As mentioned above, 8N1 38400 should do it.

Hi All,

Allright, thanks for all your help & inputs so far.
Yesterday again we connected the power supply to the motherboard (nothing else was connected to it)
and via a full nullmodem cable with hardware flow control and the settings as mentioned (8N1 38400) this immediately gave access to the L1 when the power cord was put in the PSU.

Then the experimentation could start.
running env etcetera showed that the mobo was missing CPU and GFX.

So main question is, is it the missing GFXcard that makes my Fuel mobo not start or is it something more serieus and do I really have a broken mobo that can only function as a fancy temperature meter and a clock?

The fact that no fans were attached should not be a problem as we tested that on a working Fuel and it still starts at power up command.

Has anyone an idea what this problem indicates?

any cpu fan that might of became lose and if the fuel has a cpu fan when you the working fuel did you disable the cpu fan too?

Since you have basically a bare motherboard with no fans (looking at your output), you'll need to disable environmental monitoring in order to power it up.

We tried that, but it doesn't even fire up the power supply.

We also tried the inverse: pull all memory, most fans, switches and leds from my Fuel and power it up from the L1. It does power up (and power down after 30 seconds due to the expected env. issues). At that point, the only difference between my Fuel and Francois' motherboard was that mine still had the graphics installed.

It's the "I2C: Error: <something>" message that's the problem, I think. And the question is: is it due to the missing grahics, or due to a broken motherboard?

To accentuate the special identity of the IRIS 4D/70, Silicon Graphics' designers selected a new color palette. The machine's coating blends dark grey, raspberry and beige colors into a pleasing harmony. ( IRIS 4D/70 Superworkstation Technical Report )

I2C is the protocol used by sensors to let the BIOS know things like temps, fan speeds, and supply voltages.

The

Code: Select all


   12V   Wait Pwr  10%  10.80/ 13.20  20%   9.60/ 14.40    0.19

vs.

Code: Select all


   5V aux   Wait Pwr  10%   4.50/  5.50  20%   4.00/  6.00    5.12

looks like the issue to me. You seem to have a problem with your PSU adaptor (i.e. not all rails are getting power).

If you're sure the wiring is okay, you may have damaged your voltage monitoring IC.

Finally, since the video card does have an I2C connection to monitor fans and voltage on most newer cards. It may be on the Fuel this system is integrated to the central I2C controller and not on a secondary one on the XIO bus, so the lack of a video card means an I2C error. Or the PROM is smart enough to sense the secondary chip. You may be able to disbale this somehow.
