Dell Motherboard- P/N 0WN7Y6 Dual Xeon Motherboard Front Panel Pin Layout

Q: Dell Motherboard- P/N 0WN7Y6 Dual Xeon Motherboard Front Panel Pin Layout

I've been looking for the front panel pin layout on the Dell Dual Xeon Motherboard with Dell P/N: 0WN7Y6 (it is a # zero, W, N, #7, Y, #6).
The front panel connector is 27-pin...28 spots with one pin left blank. The pin layout isn't included in the manual and I'm trying to boot two of these motherboards without the 27-pin connector. I just need to know which pins need to be jumpered in order to test for boot to BIOS.
Any assistance would be greatly appreciated.

I am attempting to transfer the motherboard of my h50-50 to a different case.  I am doing this in order to make room for a much larger video card and psu that simply will not fit in the Lenovo case.  I have run into a bit of difficulty with the 'Front panel connector'.  If you look in the 'Lenovo H50 SeriesHardware Maintenance Manual' it is on page 28 (Lenovo H50-50).  I have been trying to find the specs on what each pin is for but have been unable to find such information.  Could someone please direct me to where I can find such information or could you please provide me with the details?  Specifically I am looking for the power switch pin(s), hdd activity pin(s) etc. thanks

A:H50-50 motherboard Front panel connector pin layout

Welcome to the Lenovo Community !
There is no documentation that I am aware of that show the pinouts of the various connectors on your motherboard.  I would just use an Ohm meter on your old H50-50 case and trace wires on the old front panel plug.  Once you know how the old plug was configured you will know the pin assignments on the motherboard.

What is the layout on the motherboard for the front panel LED connectors?  The XPS 9000 manual does not specify that at all.  The motherboard itself is model number 0X501H, as given by CPU-Z.

Is the layout the same as the one listed in this thread below regarding the XPS 8500?

Hi (a post after a long time)
I've a F90M motherboard (with intel 915G chipset - i gues chipset doesn't have to do anything with front panel connections, but ... ). It came out of Acer 3700GX PC (i think its a bit old ).
Ok, now i'm trying to put it in a standard larger ATX casing. I've fitted it in and everything works fine except the front panel connections. I cannot identify the front panel connections and could only manage to identify the power switch pins on the motherboard.

I've searched over internet and couldn't find a manual of the motherboard (found manual for the PC on www.nodevice.com but it doesn't tell how to connect front panel)

so can you guys please suggest me the connections for front panel LEDs, Audio and USB.

and i really believe that you TSG guys are up to it

Thanks in advance

I upgraded from my Dell 8300 at work.  It has an I% processor so the idea was to give it to my son.  He wanted to keep his case, so I thought no big deal.  Now I am ready to toss it all out.
I cannot find a schematic for the front panel cables anywhere (motherboard DH67M01).  I need to hook up Power LED, Power Switch, and HDD LED (there is no reset button).
I only hope I have done it wrong, because now the computer will not boot (black screen with blinking cursor).

I have a Foxconn C51GU01 uBTX motherbaord. I am trying to switch the case out from the gateway to my Antec. The problem I am having is this motherboard is not labeled like any I have ever seen.

The front panel looks like this: http://support.gateway.com/s/MOTHERBD/FIC/105552/105552mvr18.shtml

If someone could help me connect the front panel correctly it would be appreciated. My desktop is just taking up space because I cant figure it out.

Thanks in Advance.

A:Motherboard Front Panel

This appears to use a standard Intel front panel pinout.

Looking at the picture pin #1 is the upper right pin in the graphic. On that side you will only use 4 pins. They are pin 1, 3, 5 and 7

Only the bottom row of pins you will also only use 4 pins. These are pins 2, 4, 6, & 8.

Pin 1 & 3 are HDD actively LED

Pins 5 & 7 are the Reset switch

Pin 9 is a No Connect

Pins 2 & 4 are Power LED

Pins 6 & 8 are On/Off Power Switch

Pin #9 should be Blank


(Reset Switch) Pin 5 is Negative, pin 7 is Positive

(On/OFF Power Switch) Pin 6 is Positive, pin 8 is Negative

If the Power LED and the HDD LED don't work properly, just turn the KK connector plug 180°

I have installed a new motherboard into my computer and have everything connected with the exception of the HDD LED, Power SW and Reset SW. For the life of me I cannot figure out where they go. The instructions are useful to the point. It shows that the 9 pins (4 on top, 5 on the bottom) but doesn't provide any instruction on which cord attaches to where. All the above connections (HDD LED, Power SW, Reset SW) consist of 2 pins. There are different colors on the pins (2 red, 2 orange, 2 green, 2 blue, 1 yellow) and only the orange/red have the positive/negative marked on them. So how do I know what connections go where?

If it matters the Power SW is Black/White, the Reset SW is Green/White and the HDD LED is Red/White.

The motherboard is a: Foxconn M61PMV AM2+ Ready

I am fairly novice with this type of stuff so would greatly appreciate any help I can get.

Thanks In Advance,

I want to connect a front panel HD audio to my computers but not sure what goes where on the motherboard headers. Just to clarify two completely different systems no connection apart from network.
The front panel lines are Bass, Centre, Gnd, Rear-R, Rear-L, Front-R, Front-L, Mic ?L & Mic-R. No problems with Gnd, but that leaves the other lines.
The motherboard headers are:
On the Gigabyte motherboard the 2 mic and gnd are obvious but what lines do the ACZ_Det , FAudio_JD & Line2 L & R go to.
On the ASUS motherboard Port1 L & R, Port2 L & R, Sense_Send, Presence#, Sense1_Retur and Sense2_Retur.
Oh where is the naming convention for these things

A:Front panel to motherboard connection

Hi Bursal, welcome to 7F!

Since you failed to fill out your System Specs, except that you are working with Gigabyte, and Asus MB's it took me a while to at least get you to where you need to go to find the information you are looking for.

For Gigabyte go to: GIGABYTE - Support & Downloads - Downloads - Motherboard
You will see that there are already a list of MB's, and you can download their manuals there, but if you don't want to go through at least 6pages I suggest you do the search.

To give you a look at what I found, and make no mistake. I have no idea if this is your board.
These pixs are from a GA-P41T-D3P User's Manual:
Descriptions to all the connections are below each diagram.

For the Asus it is a little different.
Go to: ASUSTeK Computer Inc. -Support- Drivers and Download
From there you can either automatically detect your MB or manually drill down for the manual of your board.

You already have the information you seek if you have the manuals to these boards

Hi all,
I had my power supply fry and replaced it with a new box. I have an Intel fw82371eb SL37M motherboard. I am trying to hook up the 5 front panel cords to it. I've been searching for a manual and I can't find it on any sites. I appologize for the incorrect wording. I'm not good with computer terminology. The manuals that I have seen have a single row of pins. The pins on my board are in two rows. Back row with 8 pins and 7 in the front row with the second to the left missing a pin. I need to hook up the HDD LED, POWER SW, RESET SW, SPEAKER, AND POWER LED. Does anyone know of a link to a manual or can you tell me how to hook these cords up? Thank you in advance!! If you need more info let me know....

The front panel switches of my (old) case when attached to the slots on the motherboard fail.
When all is plugged in and switched on, PC fails to turn on. The F/P switches are: | M/B SW | HD LED | Power LED +/- | RESET SW.

And I have tried the M/B SW (green and black cable) is all the available slots on the motherboard and still it doesn't switch on the computer. At first I thought it was because my PSU was only 400W and read in the manual somewhere about it needing at least 500W so I bought a 620W one and still it doesn't work.

The mobo is: GIGABYTE GA-H61M-S2PV GEN3 Intel H61 (REV B3)

Any ideas/solutions appreciated?


A:Front Panel Switches / Motherboard

You can get the motherboard manual from the manufacturers website. See here> http://www.gigabyte.us/products/product-page.aspx?pid=4065#manual

The pinout and where the cables connect will be covered in the manual. You can test the motherboard by simply connecting the two pins (the power switch pins) with a metal object (ie: screwdriver, paperclip, scrap of wire, etc.).

i just received my new motherboard, asus a8n, and i;m trying to connect my case's front usb panel with the motherboard.
The motherboard's pins are labelled:
- - - - - - - - - - - - -
| +5v P6- P6+ GND NC |
| +5v P5- P5+ GND |
- - - - - - - - - - - - -

As you can see, the first row has 5 pins, while the bottom one only 4.

My case's front panel has 8 pins, labelled

As you can understand, the pins of the panel are not grouped together.
Where must each usb panel pin go on the motherboard?

A:motherboard to usb front panel pins

My guess is that the matches are:

+5v ----> power
+5v ----> power
p5- ----> d2-
p5+ ----> d2+
p6- ----> d3-
p6+ ----> d3+
gnd ----> ground
gnd ----> ground
NC ----> unmatched

note that the p5+-,p6+- pins on the two other usb ports on the motherboard, have other names.ie one has p7-,p7+,p8-,p8+ and the other has p9-,p9+,p10-,p10+

Is my assumption correct? if yes, why is NC alone?

Hi Guys:

It's been a while since I've posted a question, however, this one is really bugging me. Recently, I've been putting together a lot of systems that have the 9-pin front-panel connection on the motherboard. The problem for me is that the ACPI/LED has only a
2-pin and most cases come with 3-pin cables. No mater which way I input the 3-pin cable, the front-panel LED light will not come on. Does anybody know what I'm referring? If you can Be of assistance, please give me some input.


A:Motherboard 9-Pin Front-Panel Connector

If the motherboard requires a 2 pin connector and the case manufacturer supplies a 3 pin connector just take the pins out of the connector and place them next to one another in the connector. There is a little tab on the connector you can lift up and slide the pin out. It's hard to explain here, but once you look at it closely you will see what I mean.

The motherboard:
Acer mb.gay09.001

A:Need help with motherboard front panel connectivity

Didn't this motherboard come out of an Acer PC? If so, you would have to look for the overall manual that came with the PC which might show the front panel pin layout. Whether there is a separate motherboard manual, I don't know. If you know the model of the Acer PC you could possibly go to the Acer website and download a manual from there.

If this is a motherboard you bought on Ebay or something, you could go back to the seller and ask them what model it came from.

I have an FIC SD11 motherboard with an Athlon 550MHz processor. I want to hook the front panel USB ports to the motherboard. I was able to find the USB pins on the motherboard for connecting the front panel cables but the motherboard does not give any indication as to what each pin is. The power panel connections the motherboard on the other hand are clearly labeled.

Does anybody have a link or a drawing of an SD11 motherboard that shows what each individual pin for the USB connections are so I can connect the cables from the front panel? I've found many pictures of the board by searching for "sd11" but none show a simple drawing which breaks down each USB pin.

(4gb ddr3, amd phenom II x4, Asus M4A88T-M/USB3)
I'm almost done but there are a few problems that i've run into.
the pront panel pins are combined in one big plugin for the ac410-m motherboard. so i need to get them out of there and plug them in into smaller pins. but i can't find a pinout diagram for the old ac410-m motherboard so the wires are unknown to me.
another problem is that i can't find a aux_in plugin on th motherboard so i guess it's if i just leave it as it is in the case.
last but not least. the motherboard says it has integrated video and audio. So do i still have to put in my graphics card or can i just leave it out of there?

I was replacing the SATA plug for my second hard drive and unknowingly unplugged all four plugs to the front panel controls. I have no idea what the make of the computer case is. My system is WinXP sp2. I have the duel core Pentium 4 chip and have loaded 2 gigs of ram. I have the ATI X800 video card and sound is on board Realtek. I have 300 gig hard drive as C: and 180 gig hard drive as D: I also have Pioneer DVD/CD read/write and NEC DVD/CD read/write.
When this occurred I first tried to plug the wires back in. Using the two LED plugs but no matter what position I plugged them into, white wire to pin 2 and green to pin 4 or reverse, and HLED plug white to pin 1 and red to pin 3 or reverse, I get no power to the front panel.
The digital readout shows F9. Also as a side note I remember there are two lights at the lower right side of the motherboard one green and to the right of it is a red light. I noted the red light does not come on at startup. Any help will be greatly appreciated. bb

OK well after years of installing just about every bit of hardware possible in various flavours of computers I finally decided to build a new one from the ground up. So here I am with my nice new case wich has front panel mic and audio out sockets, and some usb ports, and a motherboard which has pins to fit them. Only trouble is the labelling on the leads from the front panel, and the labelling on the pins on the mobo don't quite match up.
Here's what I've got on the mobo for the audio connections:
(forgive the 'code' tags, I wanted this monospaced and courier was parsing multiple spaces as one space)

aud_mic aud_gnd
aud_mic_bias aud_vcc
aud_fpout_r aud_ret_r
nc key
aud_frout_l aud_ret_l

And from the front panel I have two leads, one with mic connections, one with audio connections, labelled as follows:
Mic Cable

audio cable
Now some of these match up fairly obviously, the l and r in and out for instance... and I think vcc is the mic- power.. but there's two grounds... and what about the NC and KEY pins on the nmobo, does anything go there?
Here's how I;ve connected some at the moment:

Mic Cable | Mobo pins
.mic-power | .aud_vcc
.mic-in | .aud_mic
.ground | .aud_gnd
audio cable |
.l-ret | .aud_ret_l
.r-ret | .aud_ret_r
.l-out | .aud_out_l
.r-out | .aud_out_r ... Read more

What you have so far looks right. The NC is no connection. The Key may be for some kind of switch on a mike(not sure). I do not see a ground on the audio cable hooked up. You may want to check that.

No one has ever posted this ever. But where do the Power SW, and Reset SW go on a Lenovo K450's stock motherboard. I am so frustrated that they never put this in the manual, and it has to very specific. I can't plug it in a just "go". Anyone have an image showing exactly where each of these things go on the front panel connector?

Building a new rig, but for some reason there is no sound when I boot the machine up, the sound always come's from the front panel audio connections to motherboard and case Hd audio or AC97 wires which are both compatible on my motherboard.

The gaming case is a Antec 900, it all seems wired up correctly, just puzzled in why I can't here the beep sound when it boots up, any one got any suggestions please.

A:Front panel audio connections to motherboard Not Working!

The "Beep" sound that I think you're referring to is the post beep.

That does not come from the front panel audio connections.

That comes from the Motherboard speaker and is a separate connection.

If you want to hear the post beep, get a hold of a motherboard speaker. It's a little tiny thing that plugs into 2 of the pins on the bottom right hand corner of your Motherboard.

The function of this speaker is only for those little beeps and does nothing else of value. But it can be handy if you have a hardware failure or something like that. Each motherboard has it's own little morse code of beeps depending on what is going on. A single beep means everything is cool and it kicks off into the boot sequence.

Hi, I just purchased a Gigabyte UD3R motherboard. My computer case is at least 6 years old (don't know make) and many of the connectors don't match description to motherboard.

Cables for Audio:


RETURN R (White)

SPKOUT L (White)

SPKOUT R (Green)

GROUND (Black)

MIC BIAS (Yellow)

MIC-IN (Pink)
My case doesn't provide an HD audio module so I need to set it up for AC'97 functionality. The pin set up is as follows
Pin 1 - MIC

Pin 2 - GND

Pin 3 - MIC Power

Pin 4 - NC

Pin 5 - Line Out (R)

Pin 6 - NC

Pin 7 - NC

Pin 8 - No Pin

Pin 9 - Line Out (L)

Pin 10 - NC
Really appreciate the help. Thanks!

A:Solved: New Motherboard + Front Panel Connector Confusion

Most probably should work by:
MIC-IN to pin 1,
MIC BIAS to pin 3,
GROUND to pin 2,
SPKOUT R to pin 5,
RETURN R to pin 6,
SPKOUT L to pin 9,
RETURN L to pin 10.

Please don't mark threads solved if they aren't, less people will wander to the thread if it looks like no further help is needed.

Hi all. I have this MB in a HP Pavilion a1720n system I bought a few years ago, and have switched out the Small HP Case to a Antec 300 for more room and to add fans that the HP case did not have, and for my son to game with.

Now, I just checked here and found a similiar situation where a person switched out to a Antec 300 also, and needed the manual or picture of the FRONT PANEL PINOUTS because the letters on the board are too small to read to be able to hook up the pins to the panel.

You provided a site to where you can get the information, but it's locked out and I can't get the downlod to the manual or pic that I need to connect the pins to the front panel.

Can someone please help me in locating or sending me info for the download for this manual so I can connect the pins to the front panel. My 8 year old is ragging me out to get this fixed so he can play his games....LOL. Thanks to any help or info you can provide.

A:Asus P5LP-LE Motherboard Front Panel Pinouts

The front panel header has 5 pins(top), and 4 pins(bottom). Starting with the top far left it is as follows: N/C Reset GND HDLED - HDLED +
Then the bottom 4 pins GND PWR PWRLED - PWRLED +
I hope this can be understood.

Greetings all...I am curently in the process of transferring the "guts" (motherboard, i5 4460, etc) to a different case.  However, I am running into some difficulty getting the new separate front panel connectors of the new case matched up to the "proprietary" pin block where the black connector that was in the old Lenovo case used to go. I will include images of the motherboard connector along with the connectors from the new case I need to hook up. The only info on the motherboard is on a sticker which reads MB FRU W8s (I will include a photo for reference). Any help is MUCH appreciated!

Hey there,

I'm using the onboard sound of my ASUS P7P55D motherboard.
The back audio connectors work fine, but I somehow can't use the front panel that I connected to the mobo (yellow cable).

Is there a trick or any setting to activate it with win7 professional x64?

I also tried changing to AC97 in BIOS, didn't help...


A:Front audio Panel doesn't work (ASUS P7P55D motherboard)

Check which it is that the csae has as they are wired differently between HD Audio and AC97,

It is also possible that that fpaudio block is wired wrong and neither will work. If that is what it is it will take pulling and reseating the various wires in the block; not easy but can be done.

Would like to move my Precision T3500 Motherboard to Another box.
The Front Panel connector might be useful, but I have not found
any documentation of this.

Is there a Motherboard manual somewhere, or at least the pin definition of the Front Panel connector?
