Zero basic learning of Innosilicon T2 miners work process, maintenance tools use maintenance process, focusing on T2 miner troubleshooting, practical operation, in-depth detection, and easy-to-understand courses, making everyone an absolute miner maintenance master. The course focuses on the operation and maintenance of the Innosilicon T2, the principle and repair of the domain voltage, the judgment and replacement of the hash board chip, the signal flow and detection of the ASIC chip test point. In addition, the use of the test stand (maintenance jig), and the common faults of T2 miners such as low hash rate, high temperature, chip NG, voltage imbalance in the voltage domain, etc., do detailed explanation and processing.

Innosilicon T2 hash board repair tutorial basics
Innosilicon T2 hash board is made up of 34 voltage domains in series, with a total of 68 T1558 ASIC chips. Un the Innosilicon T1 hash board, the T2 hash board does not have a step down circuit, and the power input voltage is directly transmitted to the No. 68 chip, and then transmitted back to the No. 1 chip in turn. On the T2 hash board, there are a total of 3 crystal oscillators, which are used to generate the CLK signal. -
Innosilicon T2 hashboard main powering unit voltage measurement method
This video mainly demonstrates the voltage measure method of the power supply unit of Innosilicon T2 hash board. The main powering input voltage is 12V, the voltage of the boost circuit is 14V, the voltage of the domain powering is 0.4V, and the 1st or 3rd pin of the LDO chip is 3V, and the output voltage of pin 5 is 1.8V. Any abnormal voltage may cause the entire hash board to fail to work properly.
