Shipping and clearance cost during the warranty period

Refer to official website policy. Customer bears the shipping & clearance cost to the company, the company bears the back shipping & clearance cost.

Question 1: If the red light of miner long on

1. Normal startup, the miner dashboard is not configured, and turns off after configuration.

Solution: Use the group control software to scan the miner IP and enter the dashboard to configure the mining pool address and wallet address. After selecting the corresponding currency mode, it can work normally.

2. The dashboard configuration is incorrect and a valid pool cannot be detected.

Solution: Check whether the mining pool status is "In use", if it is "Dead", change the valid mining pool address

3. Misoperation or power outage midway.

Solution: Check whether the miner is powered on normally and whether the voltage is stable

4. Control board damaged.

Solution:Check to see if the indicator light on the control panel is red

5. Hashboard is damaged

Solution: Enter the log to view

6. Not working at high temperature.

Solution: There is a high temperature warning in the log. The temperature threshold exceeds 70 degrees Celsius and requires physical cooling.

Question 2: If the miner keeps rebooting

1. The DAG file inside the miner is updated 2-3 times a week and will be restarted at that time. This is normal.

Notice: Usually the frequency is once a week. If the frequency is too high, please contact after-sales service.

2. Detected that the hashrate is too low

Solution: Check the log or after-sales help

Notice: Contact after-sales service.

6. high temperature

Solution: Ensure that the indoor temperature is within 25 degrees Celsius, that there are no obstructions in the vents, and that indoor air circulation is normal.

Question 3: If the miner keep low hashrate

1. Based on the 24-hour average hashrate, instantaneous low hashrate is not a reference value.

Solution: Continue observation for at least 24 hours

Solution: The 10% fluctuation based on the rated model of the miner is normal.

3. The chip itself is defective and the internal circuit is short-circuited.

Solution: Return to factory

4. Lose a chip

Solution: Return to factory

5. The cable is not inserted securely and the contact is insufficient.

Solution: Disassemble the miner and replace the cables

Notice: Before disassembling the miner, you need to take photos and send the SN code of the miner and the torn off non-warranty label.

6. There is a commission on the mining pool side.

Solution: Confirm with the official mining pool

7. high temperature

Solution: Ensure that the indoor temperature is within 25 degrees Celsius, that there are no obstructions in the vents, and that indoor air circulation is normal.

8. Firmware defects

Solution: Update to latest firmware

9. Altercoins

Solution: The currency algorithm is not supported or not fully supported

10. Dual Mining

Solution: The hashrate of dual mining is relatively low

11. The pool does not support

Solution: Replace the pool

12. Algorithm not supported

Solution: Not support

13. DAG file does not have enough memory

Solution: Not support

14. The network link is unstable

Solution: Check network

15. Voltage is unstable

Solution: Check voltage

Question 4: If the hashrate of miner keep 0

1. Pool error

Solution: Replace the pool

2. Network Error

Solution: Check network

3. Network segment IP address change

Solution: Self-check the network segment to see if there are two routers. Group control can be used to manually add network segments.

4. The hashboard is damaged

Solution: Return to factory

5. Wrong mode selected

Solution: Select the mode corresponding to the currency

6. Configuration error

Solution: Reconfigure

Question 5: If the temperature of the miner is too high

1. Fans damaged

Solution: Replace fans

2. The air outlet is blocked

Solution: Check if there is anything blocking the air outlet

3. Cooling tower damaged

Solution: Symptoms of abnormally high temperature and feeling hot to the touch

Notice: Need to cut off the power immediately

4. The cooling tower is loose and misaligned

Solution: Disassemble and inspect, re-fix and apply silicone grease

Notice: Need to cut off the power immediately

5. Improper indoor temperature control

Solution: Ensure that the indoor temperature is within 25 degrees Celsius, that there are no obstructions in the vents, and that indoor air circulation is normal.

6. Hashboard short circuit

Solution: Return to factory

Notice: The indicator light of the hashboard flashes white.

7. Accumulating dust

Solution: Clean up dust regularly

Notice: Once a year in normal environment, wind cleaning is recommended

8. Short circuit

Solution: Return to factory

Question 6: If the miner' DAG loading takes too long

1. Chip reading program error

Solution: Return to factory

2. Pool link is unstable

Solution: Replace the pool

Notice: This is manifested by frequent switching between pools and a high rejection rate.

3. Short circuit inside the chip

Solution: Return to factory

4. chip not working

Solution: Return to factory

5. Individual differences in chips

Solution: Wait for the miner to show hashrate

Notice: Within 40 minutes is usually normal

Question 7: If the power consumption of the miner is too high
