4479 Desserte Nord Autoroute 440, Laval, QC H7P 6E2

This troubleshooting guide applies to all auto frequency S9 and T9 series ANTMINERs.

If the miner overview screen does not display a hardware version or BMMiner version, this indicates the mining program has not started yet. The error might appear in your miner’s kernel log as “bmminer not found, restart bmminer”.

If you encounter this issue, follow these troubleshooting steps:

  1. Reload the Firmware: Download and install the latest firmware from our official website. Run the miner for at least 20 minutes after reloading the firmware.

  2. Check Your Mining Pool Settings: Ensure there are no errors, including spelling mistakes or spaces, in the pool URLs on the Miner Configuration tab. Also, verify your miner’s connection with the mining pools as issues with these connections can cause the error.
  3. Check Network Stability: Confirm your internet and network connections are stable. Network configurations or router settings could be causing the error. Use the Ping button under “Network” and then “Diagnostic” to verify your miner can receive data.
  4. Check Fan Voltage: Compare the voltage of the front and rear fans. If the front fan’s voltage is lower, swap the positions of the fans. Also, check the kernel log for the message “Fatal Error: some Fan lost or Fan speed low”. This message indicates an issue with the fans. Replace them if necessary.

  6. Check the Control Board: Disconnect all hash boards from both the power supply unit and the control board. Reboot the miner with only the control board connected. If the error message still appears, the control board may need to be replaced.
