Miner Faults

Troubleshooting Method

1

The miner is not powered

1.Check whether the power supply and power cables are plugged in and powered
2.Measure with a multimeter for whether the power supply 6pin line has 12V output
3.Check the control board and the hashboard for burnout marks

1. Re-plug the line
2. Replace the faulty power supply
3. Replace the control board

2

Cannot scan the miner

1.Restore to factory settings or power off, press IP report button to reset
2.Check whether the miner and computer are in the same network
3.The router does not turn on DHCP or the renewal time is too long
4.Add a wrong IP segment

1. Re-find IP
2. Connect the miner and computer to the same network
3. The router turns on DHCP and sets renewal to 2 hours
4. Re-add the correct IP segment

3

Cannot visit or enter the backstage of the miner

1.The original IP is inconsistent with the current network after the miner is relocated
2. Browser compatibility issues
3. Check if the password is correct
4. Restore to factory settings or brush the control board with card

1. Change the current network to be consistent with the previous site
2. Use Google Chrome or Firefox

4

No data on the backstage or 0 hashrate

1. Check if the fan cable is plugged in or the fan is faulty
2. Check if the miner can ping the mining pool
3. Check if the fixed IP setting of the miner is wrong
4. Check if the mining pool server address and the server of the miner is set correctly

1. Replace the fan or re-plug the fan cable
2. Network troubleshooting or replace the mining pool
3. Reset and set the fixed IP again
4. Reset the mining pool server address and the server

5

The miner has insufficient board hashrate

1. Check if the miner 6Pin power line and cable are plugged in firmly
2. Check if the PSU is faulty

1. Re-plug the line
2. Replace the faulty power supply

6

Miner’s red light flashes

1. Check if the network is normal
2. Check if the machine is in high temperature protection

1. Check if the fan is faulty
2. Lower the ambient temperature and clean the dust

7

Run for a period of time with fewer chips or partial chips. Enter X to restart normally

1. Check the power supply
2. Check grounding
3. Check the network

1. Replace the power supply
2. Conduct grounding
3. Replace the network device or change the main network

8

Run for a period of time with whole hashboard chip X to restart normally

1. Check the power supply
2. check grounding
3. Check the ambient temperature and the dust of the miner

1. Replace the power supply
2. Conduct grounding
3. Lower the ambient temperature, the miner cleans the dust

9

Batch software scans a small number of miners

1. Not add all network segments
2. Check the internal network fault, whether the switch is powered off

1. Re-add network segment
2. LAN troubleshooting and check the switch

10

The miner runs for a period of time with 0 hashrate, restart to restore hashrate

1. Check if the power supply is abnormal
2. Check if the temperature is abnormal

1. Replace the power supply
2. Lower the ambient temperature, the miner cleans the dust

11

SD card recovery system failed

1. Whether the card recovery image is wrong
2. Memory card compatibility issues
3. Whether the SD card slot looses

1. Copy the file again after formatting
2. Replace the memory card
3. Clean the card slot and press the card slot to fully contact
