This T21 hash board troubleshooting training course differs from the advanced course. It only explains common fault symptoms of this hash board, such as finding only 0 ASIC chips, finding only 105 chips (or other quantities), and abnormal temperature. For these different faults, the course explains in detail the troubleshooting steps and how to complete the repair by replacing the main components. This reduces maintenance and downtime, allowing faulty hash boards to quickly return to normal operation.
