: These two pins occupy the top left (pins 1 and 2). Unlike the switch, polarity matters! The positive (+) cable must hit pin 1 to make the front light glow blue (or green).
Ensure you didn't accidentally bump a RAM stick or your graphics card out of its slot while working near the front panel header.
| Pin Numbers | Signal / Connection | Case Wire Label | Description | | :--- | :--- | :--- | :--- | | | HDD-LED (+) / (-) | HDD LED, HD LED, IDE LED | This is the Hard Disk Drive activity light. Pin 1 is usually the positive (+) lead, indicated by a colored wire, and Pin 3 is the negative (-) lead, often white or black. | | 5 & 7 | RESET-SW | RESET SW, RST SW | This connector is for the Reset button on your case. This switch is non-polarized, meaning it can be connected in either orientation. | | 2 & 4 | PWR-LED (+) / (-) | POWER LED, PLED, PWR LED | This controls the main power indicator light on the computer's front panel. Like the HDD-LED, Pin 2 is usually positive (+) and Pin 4 is negative (-). | | 6 & 8 | PWR-SW | POWER SW, PWR SW, POWER BTN | This is the most important one: the Power Switch. It connects to the case's power button. This switch is also non-polarized and can be plugged in either way. | | 9 | NC / KEY | N/A | This pin is Not Connected (NC) and is often missing or serves as a key to prevent incorrect insertion of a header. | | 10 | EMPTY | N/A | This pin is absent from the header, leaving a gap. Its absence is a key physical guide for aligning the plugs correctly. | Foxconn N15235 Front Panel Connectors - Google

The motherboard POSTed with a single, glorious beep. The screen lit up with the Foxconn logo—a silver fox leaping over a circuit-traced globe. | Row (Left to Right) | Pin Numbers
Locate all the small, two-pin connectors coming from the front of your computer case. The wires are typically bundled together. Each connector should be labeled. Common labels include POWER SW , RESET SW , HDD LED , and POWER LED .
The following pin configuration is standard for many Foxconn G31/G41 boards using this identifier: Polarity Sensitive?

: Located on Pins 1 (+) and 3 (-) . This connection is directional; if plugged in backward, the light simply won't blink during disk activity. Ensure you didn't accidentally bump a RAM stick
The header is usually arranged in two rows. Pins are numbered from left to right.

The motherboard’s "heartbeat" depended on a small cluster of pins, usually found in the bottom-right corner. To make sense of the chaos, the Foxconn followed a classic map:
Look closely at the plastic connector piece. A tiny stamped triangle indicates the positive (+) wire pin. Troubleshooting Common Connection Issues
Connect to Pin 1 and Pin 3 (Top row, leftmost two pins).
