The Z15 hash board replacement board is used to replace the faulty hash board of the Antminer Z15. Timely replacement of the faulty Z15 hash board can ensure the quick recovery of the miner. It is an essential part of the operation of the Z15 miner and is mainly responsible for calculating and generating data during the miner's operation. Its single Z15 hash board contains 3 Antminer BM1746AA ASIC chips and some essential components. Therefore, when they fail, it is recommended that you replace them with a new hash board immediately, which can reduce the loss caused by the downtime of Z15 miners.
