When the Antminer S19 Pro kernel log shows that the miner failed to obtain the power supply type version, the power supply model used does not match the miner. You can troubleshoot by the following methods.
Solution:
1. You should use the APW12 PSU 12V-15V EMC power supply for Antminer S19 Pro. This power supply is also suitable for Antminer S19, T19, and S19j Pro.
2. It is recommended to restore the miner to factory settings. For details, please refer to Antminer S19 Pro Manual.
