Pro tip: If your power LED stays off even after connecting correctly, try swapping the positive and negative leads. LEDs are directional.

If you are looking down at the motherboard with the RAM slots to your right:

Note: The Foxconn N15235 is often an OEM board (found in HP, Dell, etc.). While the pinout above covers the standard G31MX variant, some OEM chassis have proprietary blocks. If you are transplanting this board into a standard ATX case, the pinout above is correct.

Connecting the front panel of a Foxconn N15235 motherboard—a common model found in retro or budget builds—can be tricky because the layout is often color-coded but not always clearly labeled on the board itself.

header is typically a cluster of 9 pins located in the bottom-right corner of the motherboard Front Panel Header Pinout (F_PANEL)

For standard Foxconn layouts like the N15235, the pins are usually arranged in two rows. If you are looking at the header with the "missing pin" on the top right, follow this orientation: Pins (from left) Green/White wires; pin 1 is positive (+) Power Switch (PWRSW) Usually Red/Black; orientation doesn't matter The "missing" pin Bottom Row Usually Orange/White; pin 1 is positive (+) Reset Switch (RST) Usually Blue/White; orientation doesn't matter Ground or NC Important Connection Tips

Foxconn N15235 is a motherboard designation often found on models like the P4M800P7MB-RS2H

. If you are upgrading your case or troubleshooting a no-power issue, correctly mapping the front panel header (often labeled

) is essential for the power button and LED indicators to function. Front Panel Connector Pinout (Header FP1) The standard layout for this board typically uses a 9-pin header located on the bottom-right edge of the motherboard.

Here is the verified pin assignment. All pins are oriented with the motherboard lying flat, power supply off, and the missing Pin 9 on the bottom right.

| Pin Number | Signal Name | Polarity | Typical Wire Color (PC Case) | | --- | --- | --- | --- | | 1 | +5V (Power LED +) | Positive (+) | Green or White/Green | | 2 | Power LED Negative | Negative (-) | White or Green | | 3 | Power Switch (+) | Positive (Momentary) | Red or Yellow/Red | | 4 | Power Switch (-) | Negative (Momentary) | Black or White/Red | | 5 | HDD LED (+) | Positive (+) | Red or Orange/Red | | 6 | HDD LED (-) | Negative (-) | White or Black/Red | | 7 | Ground (for Reset Switch) | Ground | Black | | 8 | Reset Switch (+) | Positive (Momentary) | Blue or White/Blue | | 9 | NC (Not Connected / Empty) | N/A | N/A |

Swapping these will cause the hard drive light to act as a power light—confusing but harmless. Use the updated table above.
