Can't Fix FRONT PANEL HEADER on my Motherboard

"The front panel audio header on an Intel® Desktop Board lets you connect to a front panel audio module built into a system chassis. This document describes the header pin-out configuration for connecting a chassis with Intel® High Definition Audio (HD Audio) or AC'97 audio.
Note HD Audio headers are pin-compatible with AC'97 chassis and connectors. "

On Page 11 in the Product Guide we see that S designates the Front Panel Header.
On Page 31 in the Product Guide it shows the Front Panel Header pinout. (The Front Panel Header is designated by C in the illustration)
Again on Page 32, it shows where the Front Panel cables connect to.

In case you are not able to view the Product Guide;

Viewing the motherboard installed in the computer case, the Front Panel Header lays parallel to the bottom of the motherboard, at the Bottom Right.

It is rectangular in shape and has 9 pins.
4 pins along the Top, and 5 pins along the Bottom.

The pins are numbered Even along the Top row;
Starting from the Left side of the Front Panel Header going to the right;
Pins 2, 4, 6,and 8. There is NO Pin 10.

The pins are numbered Odd along the Bottom row;
Starting from the Left going to the right;
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the Harddrive Activity LED.
Pin 1 is for the Positive ( + ) wire. Pin 3 for the Ground wire.
In case the HDD LED is dim when the HarDDrive is active, switch the wires around. (Computer off and Anti-Static Precautions used)

B) Pins 5 and 7 are for the Reset switch, IF a Reset switch is used.
Pin 5 is for the Ground wire.

C) Pin 9 is for 5 volt ( + ) power. Not Used.
(Usually the motherboard manufacturer uses this pin to test the motherboard)

D) Pins 2 and 4 are for the Power On LED.
-> Believe Pin 2 is for the Positive ( + ) wire.
If PWR LED is dim when computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

There is No Pin 10.

The area of pins on the motherboard that the cables (Wires) go to from the Front Panel, is the Front Panel header ]

Looking at the motherboard with the Processor to the top, Ram memory slots to the right, and the white PCI slots (3) to the bottom, the Front Panel header is located parallel to the bottom right edge of the motherboard.

(The illustration has the motherboard sitting on it's right side.
Not the direction it is sitting in your computer.
In your computer the motherboard is sitting as described above )

Now I would like you to go to Page 31.
This illustration shows the various internal headers on the motherboard.
The letter C points to the Front Panel header. (J9G1)

Note that the pins in the Front Panel header are labeled with numbers.
(Pinout)

If you do not know how, and wish to, please state in a Comment.

Orient the motherboard in your mind, so that we are both looking at it in the same direction.
With the computer case open the motherboard will be sitting in this direction;

Processor to the top, (Processor fan on top of Processor), Ram Memory to the right, and the white PCI slots (3) are to the bottom.

The Front Panel header is located at the bottom Right corner. It is situated on the Right side.

(The plastic front of your computer is the Front Panel. The area of pins on the motherboard that the Front Panel cable, (Wires), connect to is the Front Panel Header)

There is two columns of pins. The header itself is vertical, (Parallel to the Right side), with pins arranged in two's going down the header.

In the Motherboard Manual (Product Guide) on Page 12, the letter S points to the Front Panel header.

The Front Panel header's pins are numbered. The numbering begins from the BOTTOM of the motherboard, and increases going towards the top.

(Page 35. The letter E points at the Front Panel header.
It is also named J9H3. Junction 9 Header 3)

Bottom RIGHT column starting from the BOTTOM of the motherboard, going towards the top,

Pins 1, 3, 5, 7, and 9.

Bottom LEFT column starting from the BOTTOM of the motherboard, going towards the top,

Pins 2, 4, 6, and 8. (There is NO Pin 10)

Page 36,

1) Pins 1 and 3 are for the HarDDrive Activity LED light. (Blinks when the harddrive is active, and in use)

2) Pins 5 , 7, and 9 are for a Reset switch. (Reset button)
This is IF a reset switch is used.

(This is what CTRL, ALT and DELete are for)

3) Pins 2 and 4 are for the Power On LED light.

[NOTE*
If the HDD Activity LED light, or the Power On LED light are dim, switch the wires around]

4) Pins 6 and 8 are for the Power On switch.

I may be confused with your problem you posted mar13974.
I thought Jumper J9H3 was for the Front Chassis Fan.
By your post, it leads me to believe you want the pin assignments for the Front Panel header on the mobo.

At any rate let's go to Intel Product Support, and the download page for the motherboard manual, for the Intel D865GVHZ desktop mobo,
(MOtherBOard),

http://www.intel.com/support/motherboards/desktop/d865gvhz/sb/CS-010872.htm

Click on the blue file name - D865GVHZ_ProductGuide01_English.pdf

After you click you may not see anything happening for up to 30 seconds. The file is downloading in the background.
(Took 16 seconds for me just now with a medium speed DSL connection)

Page 33 shows the location of the Front Panel header on the motherboard.
(C)
Page 34 details the pin assignments

Page 36 shows the Front Chassis Fan header location (Chassis front fan)
3-pin header, doesn't state the pin assignments.
With a 3-wire fan cable,
A) 1 wire is the Power wire. Generally Red
B) 1 wire is the Ground wire. Generally Black
C) 1 wire is the speed sensor wire. Reads how fast the fan is spinning in Revolutions Per Minute
(RPM) Generally Blue, but it's up to the individual manufacturer.

If the above isn't what you had in mind, please state in a Comment.

When I lived in Europe, we learned that if we bought any German made product, its price was determined by the number of buttons and knobs on the front panel. Thank God we have not entered into that craze... You have bought what we can call a General Purpose Version piece of equipment. There are going to be more connections that you will leave unused (hopefully you will not be searching for the peg where some wire goes). We teach ordinary people how to fix their computer, but in this case the product is so intricate and under warranty, that you need to go to the manufacturer and ask your questions. There is also a warranty to worry about. They are nice people and they will help you more than us; and don't forget us in the future! Thank you for your consideration and choice of our service. My name is Constantin (arzconst is my internal nickname with Fixya.com)

Intel® Desktop Boards meet the ATX motherboard design guide specification using a 9-pin front chassis header. Special attention is required when attaching the front panel connector from the chassis to the Intel desktop board.

Front Panel Header
Description Pins Hard Drive LED 1 - 3 Power LED 2 - 4 Reset 5 - 7 Power ON (Power Switch) 6 - 8Lou

most of the old motherboards dont support the audio and mic port to work both in back side(back panel header) and front side (front panel header)simultaneously...

most of the old motherboards dont support multi streaming so you cant make both the back panel header and front panel header to work at a time ie i mean you cant connect both panel header at a time ...

you can just refer to your motherboard manual for the detailed information about it ..

in your motherboard if there is any option to connect the front panel header to the motherboard other than the back panel header you can connect it to that the detailed pin information will be given in the motherboard manual ..

if you dont have the option in the motherboard to connect the front panel header seperately then you must remove the pins connected from the back panel header and you must insert the front panel header pins .
this will disable your back panel audio ,mic,linein functionalities but you will be able to connect in front panel header , this front panel header will work ..

if the motherboard is not compatible then the system assembler will leave the front panel wires not connecting to motherboard ..

like this only one panel can work at a time ,
but in the latest motherboards the multi streaming technology has been introduced so both the panels can work at a time and can play different audio on 2 different panels ...

thank you
bye

have a nice day
