The logs showed that one of the hashboards was not performing at its total capacity. After the hashboard replacement, the logs confirmed that all hashboards function correctly and the hash rate is stable.

Troubleshooting the Hashboard Issue

Here’s how to troubleshoot the hashboard issue:

  1. Check the Miner’s Status: Connect the miner to the internet and start mining. If the miner’s interface is not available after a while, the control board may have failed. Try to recover your current control board by holding the Reset or IP Report button for over 5 seconds or consider buying another one.
  2. Check the Logs: If the miner’s interface is accessible, check logs and make sure fan tests pass through. If they don’t pass and the process gets stuck on a particular fan, replace the bad fan.
  3. Try with Fewer Hashboards: Sometimes when the first hash board is not booting, the miner won’t attempt to boot the rest. So it’s recommended to try if it works with just 2 or 1 hash board before you conclude that a particular board is broken.
  4. Update the Firmware: If you had hash board failures and rebooting / resetting / re-installing / upgrading firmware did not help, then it is almost sure there is a problem within that hash board. Be careful to only install firmware that’s intended to be used with your type of S9 miner.
  5. Use a Test Fixture: You need to power on your hash board and press a button on the test fixture to begin the first test. It will report to you which chip is broken. When the failed chip is found, you need to replace it with the new one. It’s recommended to check three times using the test fixture before marking it as good.
  6. Check the Hashboard with a Multimeter: Often pretty 2-3 chips burn at the same time. You should press a button on the test fixture and then test the hash board with a Fluke 15b+ multimeter. The hash board will be tested for a while. If the hash board becomes too hot, tests should be stopped, and the hash board needs to be cooled down.

Remember, always disconnect your S9 hash board from the power source and the test fixture and let it cool before starting any repair work. Also, ensure the necessary tools and miscellaneous things are available for the repair work.

Advanced Troubleshooting Techniques

Here is some general advanced troubleshooting techniques that are often used for various issues with Antminer machines:

  1. Inspecting the Hashboard: Physically inspect the hashboard for any visible damage or burn marks. This can often indicate a hardware failure.
  2. Checking Connections: Ensure all cables are properly connected and the power supply is functioning correctly. A loose connection or faulty power supply can cause a variety of issues.
  3. Using Diagnostic Tools: Tools such as Awesome Miner can provide detailed information about the performance of your Antminer machine and can help identify any issues.
  4. Flashing the Firmware: Sometimes, issues can be resolved by updating or re-flashing the firmware of the Antminer machine.
  5. Seeking Professional Help: If the issue persists after trying the above steps, it may be best to seek help from a professional repair service.

Always take necessary precautions when handling hardware to avoid any risk of electrocution or further damage to the machine.

Preventive Measures and Best Practices

Regular Maintenance

  1. Hashrate Check: Regularly check the hashrate of the miner every two hours. Use batch management software like BTC Tools to view or log in to the corresponding mining pool website to check the hashrate status. Regularly check the miner’s information to find out whether there are errors or omissions.
  2. Power Check: Use a multimeter daily to check whether the voltage of the PDU socket of the miner is within the normal value of 220V±10%. Regularly check whether there is electric leakage in the miner. Regularly check the plant shelf and the miner socket are grounded.
  3. Network Check: Regularly check whether the spare broadband line is normal, and check it from the backend of the router or the laptop spare cable. Use the “Ping” command to test whether the delay of the mining pool used by the current miner is stable.
  4. Temperature and Humidity Check: Measure the temperature at the air inlet of the miner every day, and try to control it at 10 to 25 degrees Celsius. Measure the humidity near the air inlet of the miner every day, check whether there is condensation at the position of the shelf, miner, power line, etc.
  5. Environmental Check: Check the operation of the plant’s negative pressure fan every day to see if there is a slow speed or suspension. Regularly check the dust of the miner every month.
  6. Visual Check: Check whether the air inlet of the miner is blocked by any garbage or paper scrap every day. Check whether the indicator light of the miner is normal every day, and the red light indicates abnormality that shall be processed.

Installation and Disassembly

  1. Installation: Check the appearance of the miner for signs of violent bumping, and shake the miner to check whether there is a heat sink falling out. Before putting the miners on the shelf, check whether the cables (fan, power supply 6pin, and hashboard) are plugged in place without loosening.
  2. Disassembly: Before taking the miner out the shelf, confirm whether the miner fault can be restored to normal at the site. Before putting the miners on the shelves and taking them out the shelves, it is necessary to power off and then operate.


There are various reasons for the failure of the miner. First, check the network, upgrade the firmware, reset, check the cable, replace the power supply, reflash the control panel, clean the dust, and lower the ambient temperature, etc. If it is still not solved, it is necessary to check the power and environment. If it can’t be solved on site, it shall return to after-sales service.

Daily Operation and Maintenance Inspection

The items that need to be inspected in daily operation and maintenance of the mining farm should be recorded and improved accordingly to reduce the failure rate. These include hashrate situation, power situation, network situation, temperature and humidity, environmental check, and visual check.

By following these preventive measures and best practices, you can ensure the longevity and optimal performance of your Bitcoin miners.
