Need Motherboard Jumper/Socket Pinouts

I have the motherboard from an HP XW9400; it is made by TYAN and is essentially the S2915 motherboard with a few proprietary changes for HP. To use it, I need to know the layout of the various headers on the MB, especially the front panel header and the CPU fan headers (which are FIVE pin, not 3 or 4). Can anyone point me to a doc/pdf that gives this info? The 200+ page user Guide (Workstation Service and Setup Manual) that I did manage to find gives no info on these, though it does have a drawing of the MB and labels all the jumpers and headers on the board; it just doesn't show the pinout for these (proprietary) headers.

    Thanks for your help; however, I already have both of these manuals. The problem is that some of the jumpers/headers on the MB have been modified by TYAN for HP's XW9400, and so are proprietary. Therefore, the TYAN Manual is no help.

    If you look closely at the HP manual, it lists and describes all the jumpers and headers, but it does NOT give the pinouts, for example, for the FP header OR the CPU Fan plugs; just standard stuff like the Power plugs from the PSU.

    Can you find anything else?

  • jravin Apr 15, 2009

    Thanks again for trying to help, but that "5 pin MB pinout" you gave is a 6 pin (2x3) MB power plug (similar to the 2x2 and 2x4 power CPU of the ATX and EPS PSUs. It is not the pinout for the fan. Also, yes most fans are 3 (or sometimes 4) pins, but the 5-pin I need is seemingly nowhere to be found. I called HP Tech Support yesterday, and they were trying to find it, and they couldn't find it either; the only thing they could find was the same doc you linked in your first post. GGGGAAAAAHHHHHH! This is frustrating...

    The five pin plug I am referring to is NOT old. It is a mod made for HP for the XW9400 version of the (current) TYAN S2915 MB. I need it to figure out how to rewire my HSF to fit the board, since I have only the board and NOT the rest of the XW9400 workstation.

    It has 5 pins in a row rather than 3 or 4 as all other HSF plugs for CPU coolers I have seen.

    Nope - never did get the complete pinouts....
    If you have them, I'd love to get them.
    Thanks for asking,

    Talk about reviving a long dead thread... but if you still need the pinouts, or if you are like me, and came to this thread looking for them... They are posted in an HP discussion forum - here:http://h30434.www3.hp.com/t5/Business-PC...

  • Dennis Feb 12, 2017

    Here are the images from that HP forum - credit goes to the HP tech that posted them. If your CPU heatsink has only one fan, tie pin 5 to ground (worked for me).

    Note:
    - P23, J12, and P24 have cable detects. If this pin is not connected to Ground, the system will stop during bootup and show errors that the audio, 1394, and USB cables are not installed. Pressing F1 will cause the system to continue and boot normally. If these cable detect pins are connected to Ground, the system will think the cables are installed and boot without showing errors.

Found working description of some pins of the front panel connector:
- looking from the PCI-X slots to the edge of the board (item 25 of system board components from xw9400strg_e_c00774787.pdf, p.64)

(item 25) (item 24)
left --------- middle ----- right
capacitor xxpxoxxxs 1394 connector
xxpxxxxos
p = power switch connector
s = speaker connector
x = unknown pins
(o = key or omitted pins)

Short cutting (1s) of the power pins powered up the board, 3sec switched of power. I have been told there is no reset switch available.

Http://h50146.www5.hp.com/lib/doc/manual/workstation/xw9400/xw9400strg_e_c00774787.pdf

I think this is the document you were asking for, the figure is in: Chapter 4 - "System Board Components" - Figure4-1 - Table4-3

Hope this helps..

    Also this is the TYAN S2915 Manual, here you can find the needed figure and information in the section 2.3 (Starting from page 11). Maybe it'll be better for you to have both manuals..



    Have a nice day.

    Ok, I checked the HP xw9400 manual again, It looks like it's showing the CPU0 and CPU1 fan plugs and Front Panel plugs as you said (http://img245.imageshack.us/img245/6607/...), and for the pinouts, I think the most common for CPU fan is 3 pins but in your case, I found a website showing every kind of pinouts (http://pinouts.ru/), and there is a 5 pin mb connection (http://pinouts.ru/Power/wtx12cpu_pinout....) figure. I hope this helps.

    I see, may I ask why exactly you need that 5 pin layout? Because I think that layout should be very old, like old cpu fan pins, that deep electric/electronic engineering issue is a little bit far for me, but I'll make sure I ask a electronic engineer friend about it if you can tell me whats it needed for..

I would do so quickly, as the company is making changes to the website. Also, if you look very closely the front panel connections are usually printed on the board but can be difficult to read.
