1.5 Remove ten screws connecting the control board to hash board, then remove the control board

2. Install the Control board

2.1 Align the pins of the control board with the holes on the hashboard and insert it slowly. Ensure the pins are aligned and not bent before inserting. Do not use excessive force.

Do not place the control board face down before all the screws are properly installed to avoid bending any components on the board!!!

2.2 Align the screw holes on the hashboard with the screw holes on the control board. Secure all the screws.

2.3 Plug the fan connector into the control board

2.4 Place the hash board inside the box, aligning its edge with the internal groove. Insulating paper is placed between the baseplate and box to prevent short circuits.
