This blog post provides a guide for connecting front panel headers to the Foxconn N15235 motherboard.
Decoding the Foxconn N15235: A Guide to Front Panel Connectors Working with a classic like the Foxconn N15235
(often found in older Acer or OEM builds) is a great way to breathe life into a budget PC or a retro project. However, the trickiest part of these builds is often the "F_PANEL" header—those tiny pins that connect your case’s power button and LEDs to the board.
Here is everything you need to know to get your front panel wired up correctly. Locating the F_PANEL Header
On the Foxconn N15235, the front panel connector is typically labeled as
. You can usually find it along the bottom-right edge of the motherboard, near the SATA ports. It is a 9-pin header (a 10-pin block with one pin missing as a "key"). Pinout Configuration
Matching the tiny wires from your case to these pins is critical for your PC to power on or show activity lights. Use the guide below for the standard Foxconn FP1 layout: Polarity Matters? Top Row (Pins 1-2) Power LED (Status light) Top Row (Pins 3-4) Power Switch (Power button) Bottom Row (Pins 1-2) HDD LED (Drive activity) Bottom Row (Pins 3-4) Reset Switch Pin 5 (Bottom) Not Connected Quick Tip on Polarity: foxconn n15235 motherboard front panel connectors
, the positive (+) wire is usually colored (often red or green), while the negative (-) wire is white or black. Switches like Power and Reset work by momentarily bridging the pins, so the orientation of the connector doesn't matter. Common Pitfalls Explaining PC Front Panel Connectors
Foxconn N15235 front panel connectors are typically located on a single 9-pin header found at the bottom right edge of the motherboard
. It is important to note that "N15235" is not a specific model number but a regulatory code found on various Foxconn boards, such as the P4M800P7MB-RS2H Standard 9-Pin Header Layout
On most Foxconn motherboards featuring this header, the pinout follows this standard configuration: Pin Number Hard Drive LED (HDD LED) Pin 1 (+), Pin 3 (-) Power LED (PLED) Pin 2 (+), Pin 4 (-) Reset Switch (Reset SW) No polarity required Power Switch (Power SW) No polarity required Reserved (Empty) No connection Connection Tips & Warnings Identify Positive (+) Pins
: Look for a small triangle or "1" on the plastic connector of your case cables; this usually indicates the positive wire. On the motherboard, the positive pins are typically on the left side of each pair (Pins 1 and 2). Polarity Matters for LEDs
: If you plug the HDD LED or Power LED in backward, the lights simply won't turn on. Swapping them won't damage the board, but they won't function. Switches are Non-Polar This blog post provides a guide for connecting
: The Power and Reset switches are momentary contact switches, meaning they work regardless of which way the two-pin connector is oriented. : The header is usually labeled Related Front Panel Headers

The Foxconn N15235 isn't actually a single model number—it’s a regulatory marking found on various Foxconn-manufactured boards like the G31MXP, 45CMX, or 45GMX. Because these are older budget-friendly LGA 775 boards, the front panel connectors (labeled FP1 or JFP1) follow a classic 9-pin layout typically located at the bottom-right corner of the motherboard. Front Panel Pinout (FP1 Header)
The header is usually a 10-pin block with one pin missing (9 pins total). Use this standard guide to connect your case wires: Pin Number Polarity (+/-) 1 & 3 Hard Drive LED (HDD LED) Pin 1 (+), Pin 3 (-) 2 & 4 Power LED (PLED) Pin 2 (+), Pin 4 (-) 5 & 7 Reset Switch (RESET SW) Polarity doesn't matter 6 & 8 Power Switch (PWRSW) Polarity doesn't matter 9 Reserved/Empty No connection 10 Missing Pin (Key) Alignment marker Connection Tips
Polarity Matters for LEDs: For the HDD and Power LEDs, the colored wire (usually red or green) is positive (+) and the white or black wire is negative (-). If they don't light up, simply flip the connector around.
Switches are Non-Directional: The Power and Reset switches work by momentarily closing a circuit, so it doesn't matter which way you plug them into their respective pin pairs. Diagnosis: The Power Switch pins are likely incorrectly
Finding the Label: Look for a small "FP1" or "FRONT_PANEL" label printed directly on the PCB near the pins. If the text is too small to read, the missing pin (Pin 10) is always your reference point for the "top-right" of the block. Other Related Headers Explaining PC Front Panel Connectors
Issue 1: The PC will not turn on.
Issue 2: The Power LED is always on, even when the PC is off.
Issue 3: Hard Drive LED not working.
This is the most finicky connection on the Foxconn N15235. Modern cases use a 2-pin POWER LED connector. Insert it so that positive (+) goes to Pin 2 (bottom row, first pin from left) and negative (-) goes to Pin 4 (bottom row, second pin from left). If your case has a 3-pin Power LED with a blank middle, plug it so the blank sits over Pin 3 (top row, second pin).
