To ensure your computer boots up safely and the status lights function correctly, map your case wires to the pins according to this breakdown: 1. Power Switch (PW_SW) Pin 6 and Pin 8
: If you are moving this motherboard into a non-Dell case, you can use standard 2-pin DuPont connectors for the Power Switch and LEDs. The Power Switch (pins 5 and 6) is the most critical; the PC will boot even if LEDs are not connected. Polarity Matters for LEDs
Flashes to show read/write activity on your storage drives. 4. Power LED (PWR_LED) Pins to use: Pin 2 (Positive / +) and Pin 4 (Negative / -) dell mih61r mb front panel pinout
Plug the connector into Pins 1 and 3 . Ensure the positive wire (usually marked with a small triangle or colored wire) goes to Pin 1.
The power switch is the most critical connection. Locate . Slide the Power SW connector onto these two pins. Because it is a simple momentary switch, it does not matter which side faces left or right. Step 3: Connect the LEDs (Polarity Matters)
If the board fails to post after adapting the pinout, the CMOS battery should be removed and the "CLR_CMOS" jumper (usually a 2-3 pin pad near the battery) should be shorted. This resets the BIOS, which may be confused by the absence of the proprietary Dell daughterboard sensors. He carefully slid the exposed copper of the

Typically, this header is labeled F_PANEL or FRONTPANEL and is found on the front right corner of the motherboard, near the SATA ports. Dell MIH61R Front Panel Pinout Diagram

Micro-ATX (though mounting holes are standard, the front panel and fan headers are proprietary). 2x DDR3 Slots (Supports up to 16GB). Case Swap Considerations
Switches do not have polarity. You can slide the 2-pin PWR_SW connector over pins 6 and 8 in either direction.
