How to locate the fault part by the error code of the miner?

32

Over-temperature protection

① Whether the fan is usually working, and whether the rotation direction of the two fans is the same

② Whether the temperature of the air inlet of the fan is too high and move the miner to the lower position of the shelf

Notes: If the problem occurs massively, the abnormal miner temperature shall be taken into top priority (i.e. local fan failure).

30

Unable to connect to the mining pool

1. Some miners

① Check whether the pool is configured correctly

② Check whether the network port of the miner is tightly connected

③ Exchange network cables with normal

④ Replacing the control board

2. All miners

① Check whether the pool address is configured correctly

② Check whether the operator's network is interrupted

③ Check the local network setting (such as the setting of DNS,DHCP,ports and other settings)

22、29

Battery 12C communication is abnormal

① Restart

② Replace the power supply, you can choose the Lianli Small Steel Cannon PSU 2500W

③ Replace the control board

35、40、41

Abnormal power out put

① Restart

② Replace the power supply

③ Make sure the screws at both ends of the power terminal and the SPI cable connection are not loose.

21

Individual hash boards are not detected

① Check the power supply and cable connection of the hash board, and then plug it in again

② Put the faulty hash boards into one miner or several miners

Notes: The problem may be caused by setting up the miners and removing them off the shelf violently. Please consult the after-sales personnel before returning the faulty hash boards which are put together into one or several miners. Failure to do so many result in damage to the miner or delay in repairs.

34

The data cable connection sequence is incorrect

① Restart

② Check whether the data cable and power cable connection sequence are consistent

③ Replace the control board.

23、24、27

Hash board fault

① Power off and turn on the miner after cooling for 10 minutes

② Replace the hash board

Notes: Please consult the after-sales personnel before returning the faulty hash boards which are put together into one or several miners. Failure to do so many result in damage to the miner or delay in repairs.

25、26、28、33、36、42

Hash board fault

① No treating is needed if the hash rate is normal

② Replace the hash board

③ Restart the miner and see if the same error still occurs.

31

Individual chip abnormality

① No treating is needed if the hash rate is normal

② Replace the chip

37

The Control board or hash board does not match

Replace with the specific control board parts for this model of miner
