Step 3. Remove the daughter board. The daughter board is connected to the controller board through two board-to-board connectors. To disconnect the failed daughter board from the controller board, gently lift it up.

Step 4. Install the new daughter board. Correctly align the board-to-board connectors on the daughter board with those on the controller. Place the daughter board onto the controller board and push down gently, ensuring that the board-to-board connectors are properly connected. Use the previously removed retention screws to secure the daughter board to the controller board.

Step 5. Replace the chassis top cover. Once the new daughter board has been properly installed, reinstall the chassis top cover. For further instructions on how to reinstall the chassis top cover, please refer to Section 2.6.2.
