The Foxconn N15235 front panel connector (often labeled FP1 or JFP1) is a standard 9-pin header used to connect your case's power button, reset switch, and indicator LEDs. This header is typically located on the bottom right edge of the motherboard. Front Panel Header Pinout (FP1)
For the Foxconn N15235 (G31MXP series), the standard 9-pin layout is defined as follows: Pin Number Signal Name Description 1 & 3 HD-LED Hard Drive Activity LED (Positive on Pin 1) 2 & 4 PWR-LED Power Status LED (Positive on Pin 2) 5 & 7 RESET-SW Reset Switch (Polarity doesn't matter) 6 & 8 PWR-SW Power Switch (Polarity doesn't matter) 9 NC / Empty Not Connected (Used for orientation) Identifying Positive (+) and Negative (-) foxconn n15235 motherboard front panel connectors
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. The Foxconn N15235 front panel connector (often labeled
Note on Model Identification: The string "N15235" is often the PCB silkscreen reference. This board is physically identical to the Foxconn G31MX Series and is frequently found in HP desktops (e.g., HP dx2400/dx2450 series). If they don't light up, simply flip the connector around

| Symptom | Likely Cause | Fix | |------------------------------|-----------------------------------------------|----------------------------------------------| | PC won’t turn on | Power SW on wrong pins | Move to pins 6 & 8 | | PC turns on but HDD LED never lights | Polarity reversed or wrong pins | Flip HDD LED connector; check pins 1 & 3 | | Power LED off (but PC works) | Polarity reversed or wrong pins | Flip Power LED connector; verify pins 2 & 4 | | Reset button doesn’t work | Connected to wrong pins (e.g., pins 7 & 9?) | Use pins 5 (GND) and 7 (RESET+) | | Short press = reset, long press = power | Power SW and Reset SW swapped | Exchange the two 2-pin connectors |
If you see "F_AUDIO" or "USB," you are in the wrong area. Those are for audio jacks and USB ports, not power/reset switches.
