SGI: Hardware

I was quite lucky to get the main node of an Onyx 350 configuration, so it came with all the extras (PS2 connectors, usb card, M-Audio card, DVD drive).
Here are some more pictures of the install process :

that's great!
congrats

*If* bplaa.yai wants to add additional fans like the three 60mm units that came with your O350, and his nodeboard doesn't include the fan headers like your 1GHz systems does, there might be a workaround <that might also stop the L1 fan warnings>.

He may be able to use 60mm PWM fans routed through a PWM splitter to the 4-pin PWM fan header the radial exhaust fan <replaced by the V10> was originally attached to.

*NOTE*: The industry standard for PWM fans specifies a specific wire color codes and header pin assignments. <see page 19> :

Pin 1 - Black <ground>
Pin 2 - yellow <12VDC>
Pin 3 - green <sense>
Pin 4 - blue <control>
The Papst RER 101-36/12 radial fan that was originally connected to that fan header has non-standard wire colors. The Papst spec sheet lists the color code/function for the RER 101-36/12:

red - 12VDC
blue - ground
white - tach <sense>
violet - PWM <control>
When compared with the Papst wire colors, the photos of bri3d and bplaa.yai's O350s seem to indicate SGI used a non-standard pin assignment:

Pin 1 - 12VDC
Pin 2 - PWM
Pin 3 - tach/sense
Pin 4 - ground

as well as a much larger connector housing/pin spacing, so the connector from the original Papst fan will have to be used. I don't have an O350 to confirm those assignments - so if anyone intends to try this meter the header pins first!!

There is one other long shot - there appears to be an unused three-pin fan header <next to the four-pin PWM fan headers>. This photo <zoomed and cropped from one posted in this thread>, #1 and #2 are the four-pin PWM exhaust fan headers; and #4 is what I suspect might be a three-pin fan header. I say suspect, because the cable attached to the <adjacent and similar>header #3 appears to be routed to the power supply fan at the front of the case <#5>: The function of this header will also need to be metered to prove or disprove its function, but if it is a fan header, it *might* be the intended location for the attachment of the Odyssey fan in the factory version of an Onyx350 IP. If #4 is a three-pin fan header, SGI may not have used standard pin assignments < as was also noted in the Fuel >.

Postscript: SGI's nonstandard pin-out for the 3-pin fan header <labled as #4 in the photo above> is apparently:

Pin 1 - 12VDC
Pin 2 - Tach
Pin 3 - Ground

It looks like that recondas' suspicion about header #4 was right; by connecting a 80mm fan wired the "fuel way", we get an env rpm reading for the ODY fan. Maybe also worth to note that my first attempt with a crappy low rpm pc fan didn't work (fan was running but nothing reported to L1), but the second attempt with the old fans from my O300 worked.
Now the FAN #4 Warning is gone
Full env :

Glad to hear that bplaa.yai. Since attaching a fan does stop the warning messages about fan #4, and according to the L1 env, fan #4 is assigned to the Odyssey graphics board, it seems almost certain the 'factory' IP V12 had a fan.

My next guesstimate is that there's an 'exhaust' port for the factory IP Odyssey fan <it appears to be closed in photos of the Origin 350>:

In my system (which I have now got some photos of) the DM3 board has it's own cooling fan attached underneath, which is the same I guess as the one used in the graphics option.

Thanks for taking the time to take and post those photos Toby!

I used Toby's photos to look up the fan. It's a Delta BFB0712H radial fan <also known as a blower>, 75mm x 75mm x 30mm, 2900RPM, 11.3CFM. Both Delta's spec sheet and Digi-Key's web page list the BFB0712H as a two-wire fan <no tach sense/speed control>, but Toby's photo clearly shows a three-wire fan, so this one might be an SGI custom.

Interesting arrangement on the DM3. It appears the fan is attached to a metal shroud on the bottom of the DM3. It apparently draws air across the DM3, through an opening in the shroud and then exhausts out the opening on the case below the DM3.

OK, I finally took the time to finish my cooling setup.
I went for 3 delta fans (FFB0612VHE, spec sheet here ), mounted on a home made aluminium mount.
The only drawback is that I only get rpm ready from one fan out of three.

Nicely done! Makes for a very clean installation - and I'm sure they more a fairly significant amount of air.

I'm working on getting it inserted and the cooling rerouted right now!

The good news: The V10's huge heatsink clears the node board (with the metal box removed, obviously) by a fair amount.
The bad news: I had to remove the back connector plate from the V10 - it looks like the ones in real Onyx 350s might have them, but the back plate on this Fuel V10 wouldn't clear the serial daughtercard.
The really stupid news: To seat the V10 in the slot, *both* blower fans must be removed. Once the V10 is slotted in, the second blower can be put back. What a pain.

Once I get the cooling set up I'll see what the software thinks of this setup

IT WORKS!

Got to do a reinstall to get all the graphics stuff in my IRIX - and I don't have an OHCI USB controller handy, so no X for me yet, but this is a viable, working config!

The PROM does not show the Odyssey board. Do i need to enable the PROM automatic update or some L1 settings to make the system detect and update the PROM?

It wouldn't hurt anything try the PROM command "update", but something doesn't seem right. Both of the ones I've done automatically appeared during the first power-up after installation.

Can you post the output of the L1 command "serial all"?

Considering that rough handling displaced the serial daughterboard, it might not be a bad idea to make sure the XIO/PCI riser is fully seated/undamaged.
