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 foxconn n15235 motherboard front panel connectors
. 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:
, 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
The Foxconn N15235 motherboard follows a pinout layout heavily influenced by HP/Compaq OEM standards rather than the open-market ATX standard. By utilizing the pin map provided in this paper, technicians can reliably restore front panel functionality. When working with LEDs, always assume polarity matters; for switches, assume it does not.
Disclaimer: This paper is provided for informational purposes. Motherboard revisions may alter pinouts slightly. Always consult the silkscreen on the physical PCB if legible.
The front panel connectors on a Foxconn N15235 motherboard are located on a specific header labeled FP1, typically found at the bottom right of the board. This 9-pin cluster is standard for many older Intel-based boards and connects your case's power button, reset button, and status LEDs. Header Pinout Diagram (FP1)
The header consists of two rows of pins. One pin in the corner is "missing" (NC), which helps you orient the connectors. Description Top Left (Pins 2 & 4) PLED Pin 2 (+), Pin 4 (-) Top Right (Pins 6 & 8) PWRSW Power Switch Orientation usually doesn't matter Bottom Left (Pins 1 & 3) HDLED HDD Activity LED Pin 1 (+), Pin 3 (-) Bottom Right (Pins 5 & 7) RESET Reset Switch Orientation usually doesn't matter Pin 9 NC Empty / No Connection Used as a key Key Connection Tips
Identify Polarity: For LEDs (Power and HDD), matching the positive (+) and negative (-) ends is crucial for the lights to work. Look for a small triangle symbol on the plastic connector; this indicates the positive wire.
Switches: The Power and Reset switches are momentary buttons, so they will function regardless of which way they are plugged into their specific pin pairs.
Speaker Header: If you need to hear BIOS beep codes, the Speaker Header is often a separate 4-pin block nearby, distinct from the main FP1 header.
USB and Audio: Do not confuse the FP1 header with the F_USB or F_AUDIO headers. USB headers usually have a different missing pin configuration (pin 10) to prevent incorrect installation. For detailed visual confirmation, you can refer to the Foxconn G31MV-K Manual on ManualsLib, which uses the same N15235 layout.
Are you currently building a new system with this board, or are you troubleshooting a power-on issue? How to connect front panel connectors to the motherboard
To connect the front panel cables to a Foxconn N15235 motherboard, you need to locate the FP1 header Top Row (Pins 1, 3, 5, 7, 9):
, typically found along the bottom edge of the board. This header uses a standard 9-pin layout (though it may appear as a 10-pin block with one pin missing). FP1 Front Panel Pinout Diagram
The pins are generally arranged in two rows. Match the labels on your case's small plastic connectors to these pins: Pins 1-2 (Left) Pins 3-4 (Middle) Pins 5+ (Right) PLED+ / PLED- (Power LED) (Power Switch) (Reserved/Empty) Bottom Row HD_LED+ / HD_LED- (Reset Switch) (Empty/NC) Connection Steps Power LED (PLED):
Connect the positive (+) and negative (-) wires to the top-left pins. Power Switch (PWR_SW):
Connect these to the two pins next to the Power LED. Polarity (positive/negative) usually does not matter for switches. HDD LED (HDLED): Connect these to the bottom-left pins. Reset Switch (RESET): Connect these to the bottom pins next to the HDD LED. Alignment Tip:
The colored wire is usually positive (+), and the white or black wire is negative (-). Many headers also have a small arrow on the back of the connector indicating pin 1. Verification How to connect Front Panel Connectors to the Motherboard
The Foxconn N15235 motherboard is typically found in older OEM systems (e.g., Acer Aspire M3910, M5810, or similar desktops from around 2009–2011).
Here’s the standard front panel header pinout for that board.
The Foxconn N15235 front panel connector is not as scary as it looks. The secret is ignoring the missing pin and focusing on the 2x5 layout (with one missing). Memorize the four key pairs:
Pro tip: Take a clear photo of your FP1 header with your smartphone. Zoom in. Use a white gel pen to mark pin 1 on the motherboard itself. This will save you hours of headache if you ever disconnect the wires again.
If you found this guide helpful, bookmark it. The Foxconn N15235 is aging, but with the right front panel wiring, it can still power a home server, a retro gaming rig, or a basic office PC for years to come.

Once upon a time, a DIY enthusiast named Leo was breathing new life into an old PC built around the reliable Foxconn N15235 Go to product viewer dialog for this item. (also known as the Bottom Row (Pins 2, 4, 6, 8, 10):
). He had the CPU seated and the RAM clicked in, but he hit a wall: a bundle of tiny, loose wires from the case labeled "PWR SW," "RESET SW," "HDD LED," and "PLED."
Without a manual, those nine mysterious pins in the bottom-right corner of the board felt like a puzzle. Here is the "map" Leo used to solve it. The Secret Map: FP1 Header Foxconn N15235
, the front panel header is typically labeled FP1. It consists of two rows of pins. To get it right, Leo looked at the board so the missing "key" pin (NC/No Connection) was on the far right of the bottom row. Top Row (Starting from Left):
Pins 1 & 2: Power LED (PLED). These light up the case when the PC is on.
Pins 3 & 4: Power Switch (PW-SW). This is the most critical connection; it allows the case button to actually turn the PC on. Bottom Row (Starting from Left):
Pins 1 & 2: HDD LED (HD-LED). These make the light flicker when your hard drive is working.
Pins 3 & 4: Reset Switch (RESET). This connects the case's reset button. Pin 5: This pin is usually empty (NC). Leo’s Three Golden Rules
As Leo carefully slid the connectors onto the pins, he kept these tips in mind from expert guides: Explaining PC Front Panel Connectors
Note: Exact labeling and layout can vary by BIOS/board revision and by Foxconn OEM partners; treat this as the common mapping for boards in this series.
Group your case’s front panel connectors. Identify them by their labels:
Below is the standard pinout for the N15235’s front panel header (viewed from above with the board flat, header closest to bottom edge of case):
| Pin | Signal | Color (typical) | Pin | Signal | Color (typical) | |-----|----------------|-----------------|-----|----------------|-----------------| | 1 | HDD_LED+ | Red/White | 2 | PWR_LED+ | Green/White | | 3 | HDD_LED− | White/Black | 4 | PWR_LED− | White/Black | | 5 | GND (Reset) | Black | 6 | PWR_BTN+ | Yellow/Red | | 7 | RESET+ | Blue/White | 8 | PWR_BTN− | Black/White | | 9 | RESET− | White/Black | 10 | N/C (key) | – |
Note: Pin 10 is often missing (no pin). This is the key – align the connector’s blocked hole here.
