Here’s a step-by-step guide on how to disassemble and assemble the control board from your ANTMINER S9 SE/S9k:


  1. Power down the miner: Always ensure the miner is completely powered down before you begin any hardware adjustments. This will prevent accidental damages from power surges.
  2. Remove the casing: Most miners have a shell or casing that houses the internal components. You will usually need to remove some screws to take off this casing.
  3. Identify the control board: The control board is usually located at the top or side of the miner. It has several cables and connectors leading into it.
  4. Detach the connectors: Carefully remove all the connections leading into the control board. These may include power cables, data cables, and fan connectors. Be gentle to avoid damaging the connectors.
  5. Unscrew the control board: Once all the connections are removed, you can unscrew the control board from the miner’s frame.


  1. Attach the control board: Place the control board back onto the miner’s frame and secure it with the screws.
  2. Connect the cables: Reconnect all the cables that you previously detached. Make sure each connector is secure and fits snugly into its socket.
  3. Replace the casing: Once everything is connected, you can replace the miner’s casing. Screw it back in place to secure it.
  4. Power up the miner: Now you can power up your miner. Check the miner’s interface to ensure everything is working correctly.

Remember that handling the control board and other components of a miner requires some degree of technical knowledge. If you are unsure about any of these steps, consider reaching out to a professional or the support team of your miner’s manufacturer.
