The Iron Pi requires a 12 to 24 volt DC power supply capable of delivering at least 1 amp to the Iron Pi. Connect the power supply's positive terminal to the Iron Pi's +12-24V terminal, and the power supply's negative terminal to the Iron Pi's GND terminal. When using a typical AC/DC power supply with a floating DC output, connect the power supply negative output to ground.

To ensure equipment and operator safety, connect a properly sized fuse between the AC power entrance and the AC/DC power supply, bond the enclosure or backplate to the ground wire, and connect the Iron Pi's CHAS terminal to chassis ground.

When you apply power to the Iron Pi, the Power/CPU light should immediately turn green, and then blink orange to indicate disk activity:
