[OT] Trying to Find the "how to connect"l guide of an NS30/35/36-FS motherboard
Hello all,
I've been given an old tower made by Fujitsu-Siemens, with an NS30/35/36-FS rev-C2 motherboard inside, which seems to have been made by a company named DFI. I have already found some data about it (max processor speed, type of memory used, etc), but I'm missing one important part: the physical layout of all connectors, and especially the description of the pins of the headers (onto which the frontpanel stuff - buttons, leds, etc - is connected). I've ofcourse also tried to search the DFI companies site, but probably due to the motherboards age (2003) the info (and downloads) for it seems to have been purged. :-( tl;dr: Does anyone know or have (a link to) the "how to connect" guide to an "NS30/35/36-FS" (rev-C2) motherboard for me ? TIA. Regards, Rudy Wieser |

TIA. Regards, Rudy Wieser Time for the multimeter I'm afraid. You're in Smithsonian country. I'd get all excited, but Google search is useless right now. Google and Bing used to give almost equal results. Now, bing.com is beating them a bit in terms of pages returned. Google used to do "load shedding", which is why I had to tell people occasionally it could take 24 hours to find a breadcrumb for them. It's a lot worse now. ******* Bing.com gave me this for example. I'm not expecting to find your exact board, and the purpose of showing this is to "show what DFI was thinking". https://www.manualslib.com/manual/10...?page=7#manual Front panel header example. https://www.manualslib.com/manual/10...page=20#manual Note that ODM boards, made by DFI for FS, do not have to follow retail motherboard conventions. A retail motherboard from the era might have up to 20 pins for the panel header. Whereas ODM standards are to use an 8 pin pattern, with PWR/RST/IDELED/PWRLED type functions. On page 20 for example, pins 3,4,5,6,7,8,9,10 are the ODM subset of pins. Two switches, two LEDs. DFI could simply not put header pins into the other holes, to satisfy FS as a customer. And the Green Switch might be a Sleep button, but I can't be sure of that. PCs have had more than two switches on the front, but I don't know what that was for. They also had Power LED, IDE LED, as well as Message LED, where Message LED might have lit up when an email poll picks up new mail. I don't think I've owned a PC with that on it :-) Paul |

When you saw "It's safe to turn off your PC" on the VGA screen, you reached for the switch on the back to pack it up for the night. The really early machines, definitely: big red lever switch on the side. You definitely knew that was a power switch! However, some towers were AT era and had the power switch on the front; you could tell as it was a two-position switch, in for on. having just looked at an old tower, I've remembered another reason some cases had two buttons on the front: some had a reset button. I always felt nervous about that: too easy to hit by mistake! IMO if you're going to have a reset button, it should always be two in series.

[OT] Trying to Find the "how to connect"l guide of an NS30/35/36-FS motherboard
Paul,
Time for the multimeter I'm afraid. You're in Smithsonian country. My apologies, I forgot to mention its still connected & working. I just don't want to go yank the connections without knowing where they belong - I am/was intending to move the board into another case. I'd get all excited, but Google search is useless right now. I did, and again found that out. :-( Not that DDG did any better (less cruft though). Bing.com gave me this for example. I'm not expecting to find your exact board, and the purpose of showing this is to "show what DFI was thinking". :-) All I see there is the names of motherboard related connectors randomly strewn over a white page. A nice example of how /not/ to convert a PDF. Note that ODM boards, made by DFI for FS, Facepalm. That "for FS" only now made me realise that thee "-FS" on the end of the motherboard ID is short for "Fujitsu-Siemens". do not have to follow retail motherboard conventions. Which is, to me, another good reason to get the exact specs. Although none of the frontpanel stuff is going to supply current on those pins, connecting two output pins to a simple LED will be confusing. Worse: connecting the powerbutton over them could destroy either pin. :-( Thanks for the searching and links though. Regards, Rudy Wieser |

Only things that won't be obvious is the orientation of the LEDs, which you can _probably_ determine with a multimeter (most multimeters will light an LED, though you might need to shade it to see it [perhaps excluding blue ones, but XP-era machines _probably_ won't have those]). -- J.

John,
Ah. At least you can then sketch them as you unplug. Indeed. I found the front panel header (the most important one because of the multiple connectors being plugged onto it ) due to the non-standard usage and the omnious scribblings under them. 20-pins with pin 11 broken out. Alas, those scribblings do not make it clear which pins are actually used. As such I've only been to identify the connected ones (the power and HD leds and ofcourse the power switch), but no such luck for the "reset" "G-led"(?) and "speaker" markings. I've already tried to match them up with some standard configurations, but have not been able to find a match. Most of the other headers are boxed with slotting and all of different size, so not that easy to mix them up. The only one I have to jot down are the to dual USB headers. Althoug later versions can be inserted in either orientation, these ones do not look like them (10 pin, last two pins not used). That leaves a few small 4, 3 and 2 pin slotted headers that currently are not used. Could make some guesses about them related to their forms & location, but thats perhaps for a later time. (Remember - if there are no omitted pins or other such indication - to note the orientation of the connector[s]!) :-) I noted down the color of the wires going to each pin. Only things that won't be obvious is the orientation of the LEDs, which you can _probably_ determine with a multimeter (most multimeters will light an LED Yup, especially when the multimeter has a "diode" position in its ohms range. Though normally I just plugged the "new" leds in and checked if they would light up. If not I reversed their polarity. Hasn't failed me yet. :-) Thanks for the suggestions. Regards, Rudy Wieser |

Small ones, I'd guess might be for case fans, or audio in/out, as you say, depending on location.

I don't know if there is any standard for case LED/switch wires!

I've been given an old tower made by Fujitsu-Siemens, with an
NS30/35/36-FS rev-C2 motherboard inside, which seems to have been made by a company named DFI. I just found the towers model name, embossed black-on-black (almost invisible) on the front right side: it seems to be a "Scaleo 600". Alas, it seems to have been sold with different motherboards and the found "users manual" is written for exactly them, users (no mentioning of the wiring of the motherboard). Regards, Rudy Wieser |
