3 Common Malfunctions and Treatment

3.1 Common Malfunctions

The red and green status indicators of the mining machine can indicate the abnormal state of the main mining machine

When the miner software detects an abnormal state, the miner background page and indicator will indicate the current abnormal state at the same time.

3.2 Malfunction Elimination

3.2.1 Power Supply

Situation 1

When the miner is powered on, the fan does not rotate and the network port light does not turn on.

Tips:

• Check whether the power connector is loose or falling off, and whether the power cord is inserted firmly.
• Check whether the fan rotates, if not, the power supply needs to be replaced.
• Use the multimeter to check whether the power supply is 11-13V output.

3.2.2 Network

Situation 1

The new miner cannot obtain an IP address

Tips:

• Check whether the Ethernet interface is plugged in and whether the Ethernet status light is on.
• Ensure that the IP address of the miner and the PC are in the same network.
• Make sure that the miner network setting DHCP is turned on. If you do not confirm, press and hold the ‘Reset’ button for 7 seconds to restore the factory settings.

3.2.3 Fan

Situation 1

The fan does not rotate after power on.

Tips:

• Check whether the fan cable is inserted firmly.
• Change the fan interface crosswise to check whether it is a fan problem or a control board interface problem.

Situation 2

The fan starts after power on, but the miner software reports that the fan is abnormal.

Tips：

• Fan speed is insufficient in some gears

3.2.4 High Temperature Protection

Situation 1

The miner is closed due to high temperature protection

Tips:

• Check whether the ambient temperature is too high. (above 35℃)
• Check whether the air inlet and outlet of the fan are blocked (for example, the air inlet and outlet are facing the wall, and there are too many attachments such as dust and catkins).
• Restart at least 10 minutes after the high temperature protection, and observe whether the temperature of the miner is stable after running.

3.2.5 Low Computing Power

Situation 1

The background software prompts “Unable to start the computing board”, the computing power is 0.

Tips:

• Restart the miner to see if it can be restored.
• Change the power cord of the board to eliminate the problem caused by the power supply.
• Cross-exchange data cables with normal hashrate boards to eliminate cable problems.

Situation 2

The local average computing power is normal, but the pool computing power is low.

Tips:

• Check whether the network has high latency.
• Replacing the pool comparison test, there are currently some pools that cannot adapt to the appropriate difficulty, resulting in low computing power.
