Motherboard Layout
The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires from the Front Panel go to, is the Front Panel header.
JFP1 is the Front Panel header.
JFP2 is an additional header. To be discussed after JFP1.
JFP1 is on the Right/Bottom corner. It is placed Vertically.
(Parallel to the right bottom edge of the motherboard)
Above it's left corner is JUSB2. (Front Panel USB header 2)
Above JUSB2 is the SATA2 connector. To the left of the SATA2 connector is the SATA1 connector.
To the left of the SATA1 connector is the CMOS battery.
The contact pins are arranged in two columns.
4 pins on the Left side, 5 pins on the Right side.
Go to Page 14. JFP1 pinout, and JFP2 pinout, is at the Bottom of the page.
JFP1:
Starting on the Bottom going towards the Top, Right side;
Pins 1, 3, 5, 7, and 9
Starting at the Bottom going towards the Top, Left side'
Pins 2, 4, 6, and 8.
A) Pins 1 and 3 are for the HarDDrive activity LED. (Light)
Pin 1 is for the Positive ( + ) wire.
IF the HDD LED is dim when the harddrive is active, switch the wires around.
B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.
C) Pin 9 is N/C. Not Connected. (Probably 5 Volts positive, and used by the factory only)
D) Pins 2 and 4 are for the Power On LED. (Light)
Pin 2 is for the Positive ( + ) wire.
IF the PWR ON LED is dim when the computer is on, switch the wires around.
E) Pins 6 and 8 are for the Power On switch.
JFP2:
Below JFP1 is a header that is placed Horizontally. It is parallel to the Bottom edge of the motherboard. This header with 13 pins in it, is the JLPC1 header.
(Starting on left side at the Top row; 4 pins, no pin, 2 pins.
Starting on the left side at the Bottom row; 7 pins)
To the left of the JLPC1 header is the JFP2 header.
4 pins across the Top row, 3 pins across the Bottom row.
The top 4 pins across the top are for an internal speaker. Used to hear BIOS Beep Codes.
Starting on the Left side coming towards the Right, top row;
Pins 2, 4, 6, and 8.
No indication of polarity.
Believe pin 2 is for the Positive wire, and pin 8 is for the Negative wire.
Starting on the Left side coming towards the Right, Bottom row:
Pins 1, 3, and 5.
These pins are ONLY used for a Power On LED light, that has 3 wires.
Used for a dual color Power On LED.
(One example; Green Turbo, Yellow normal)
The rest of the pinouts are listed in the manual.
