Common Issues and Troubleshooting Steps

1. Power Supply Problems

Symptoms: The miner fails to power on, or the control board shows no signs of activity.

Troubleshooting Steps:

• Check the Power Connection: Ensure the IEC C19 16A power cable is securely connected to both the control board and the power supply unit.
• Verify Power Output: Use a multimeter to confirm that the power supply is delivering the correct voltage (typically 12V or 220V, depending on your setup).
• Inspect for Damage: Look for burnt connectors or damaged cables. Replace any faulty components immediately.
• Test with Another PSU: If available, try using a different power supply unit to rule out PSU-related issues.

Preventive Tip: Regularly inspect power cables and connectors for wear and tear, especially in high-temperature environments.

2. Network Connectivity Issues

Symptoms: The miner cannot connect to the network, resulting in failed mining operations.

Troubleshooting Steps:

• Check Ethernet Cable: Ensure the Ethernet cable is securely connected to both the control board and the router.
• Test Network Port: Connect another device to the same Ethernet port to verify functionality.
• Restart Router: Power cycle your router to resolve potential network congestion or configuration errors.
• Update Firmware: Ensure the control board’s firmware is up-to-date, as outdated versions can cause connectivity issues.

Preventive Tip: Use high-quality Ethernet cables and keep your network infrastructure well-maintained.

3. Overheating

Symptoms: The control board shuts down unexpectedly, or performance drops significantly during operation.

Troubleshooting Steps:

• Monitor Temperature: Use the miner’s monitoring interface to check the temperature of the control board. If it exceeds 35°C, take immediate action.
• Improve Ventilation: Ensure adequate airflow around the control board and the entire mining rig. Consider adding additional fans or upgrading your cooling system.
• Clean Dust Accumulation: Remove dust and debris from the control board and surrounding components, as buildup can impede heat dissipation.
• Relocate Equipment: If ambient temperatures are too high, consider moving the mining rig to a cooler environment.

Preventive Tip: Regularly clean your mining setup and invest in a robust cooling system to prevent overheating.

4. Firmware or Software Glitches

Symptoms: The miner behaves erratically, fails to respond to commands, or displays error messages.

Troubleshooting Steps:

• Reboot the Miner: Power cycle the miner to resolve temporary software glitches.
• Reinstall Firmware: Download the latest firmware version from the manufacturer’s website and follow the installation instructions.
• Reset to Factory Settings: If the issue persists, perform a factory reset to eliminate corrupted configurations.
• Check Logs: Review the miner’s logs for error codes or unusual activity that could indicate the root cause.

Preventive Tip: Regularly update firmware to benefit from performance improvements and bug fixes.

5. Hardware Failures

Symptoms: The control board is unresponsive, or specific functions (e.g., hash rate monitoring) stop working.

Troubleshooting Steps:

• Inspect for Physical Damage: Look for burnt components, loose connections, or visible damage on the control board.
• Test with Another Board: If possible, replace the CB4 V10 with a spare control board to determine if the issue lies with the hardware.
• Contact Support: If the problem persists, reach out to WhatsMiner’s customer support for professional assistance.

Preventive Tip: Handle the control board with care during installation and maintenance to avoid accidental damage.
