Foxconn N15235 Motherboard Front Panel Connectors -

The front panel header on the Foxconn N15235 is typically a single block of 10 pins arranged in two rows of five (often labeled FP1 or JFP1 on the board). However, the key challenge is that not all ten pins are active, and their functions are not always arranged in the common Intel standard (Power LED, Power Switch, HDD LED, Reset Switch in a specific 2x4 layout). Based on technical documentation for this chassis series, the pinout deviates slightly. A verified layout for the N15235 is as follows:

| Pin | Signal (Row 1 - Odd Pins) | Pin | Signal (Row 2 - Even Pins) | | :-- | :--- | :-- | :--- | | 1 | HDD LED (+) | 2 | Power LED (+) | | 3 | HDD LED (-) | 4 | Power LED (-) | | 5 | Ground | 6 | Power Switch (+) | | 7 | Reset Switch (+) | 8 | Power Switch (-) | | 9 | Reset Switch (-) | 10 | Key / No Pin |

| Pin | Signal | Description | |-----|------------|---------------------------| | 1 | HDD_LED+ | Hard disk LED positive | | 2 | HDD_LED- | Hard disk LED negative | | 3 | RESET_SW- | Reset button negative | | 4 | RESET_SW+ | Reset button positive | | 5 | PWR_LED+ | Power LED positive (green)| | 6 | PWR_LED- | Power LED negative | | 7 | PWR_SW- | Power switch negative | | 8 | PWR_SW+ | Power switch positive | | 9 | NC | No connection | | 10 | KEY | Missing pin (key) |

Note: Polarity for switches doesn’t matter (they just close a circuit), but LEDs require correct + / – to light.

Typical case wires:

These connectors are "dry contacts." They function by shorting the two pins together momentarily.

Correction for Standard Foxconn N15235 Layout: On many OEM variants of this board (HP versions), the pinout is often simplified:

However, the most common verified N15235 configuration is:

Let us stick to the verified G31MX / N15235 standard: foxconn n15235 motherboard front panel connectors

(Note: Because Pin 8 is physically missing on many boards, Pin 10 often serves as the second pole for the power switch. If your connector has two holes, place it over the two available pins adjacent to the missing key).

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. The front panel header on the Foxconn N15235

The Foxconn N15235 is a compact motherboard commonly used in small form-factor desktops and all-in-one systems. This guide explains the front panel connectors (power, reset, LEDs, audio, USB) you’ll find on the board, typical pinouts, and practical tips for connecting case cables or troubleshooting common issues.

You will have small 2-pin or 1-pin connectors from your case labeled accordingly. Follow these steps:
