If your Power LED connector is 3-pin (common on older cases), the middle pin is unused. You may need to split it into two 1-pin connectors or carefully plug the 3-pin so that the two active wires go to pins 2 and 4, leaving the middle hole over pin 3 (which is HDD_LED− – no conflict but may cause odd behavior if connected). Convert to 2-pin by removing the unused middle wire.

Connecting the front panel cables of a computer case to the motherboard is often considered the most tedious part of building or upgrading a PC. If you are working with a classic , locating the correct pins for your power button, reset switch, and LED lights can be challenging. Foxconn boards frequently use standardized layouts, but the labels printed directly on the board can be incredibly small or difficult to read.

Your motherboard will have several internal headers. These are 9-pin blocks that can each support two USB ports. These pins are keyed to prevent incorrect connection, so plugging in your front-panel USB cable should be straightforward as it only fits one way. A user tip for the N15235 board is to try plugging into a different USB header if a port isn't working.

HDD/Activity LED (HDD_LED)

The "front panel connector" (often labeled ) is the crucial link between your computer case and the motherboard. It's a small block of pins, usually at the bottom-right corner of the board, that controls your power button, reset button, hard drive activity light, and power-on light.

The standard 9-pin layout on this motherboard follows a universal Intel-style front panel design. Here is how the grid is numbered and mapped:
