3. Setup Instructions
Proper setup is crucial for the performance and longevity of your hydro-cooled miner. Ensure all components are handled with care.
- Unpacking: Carefully remove the miner from its packaging. Inspect for any visible damage during transit. Keep all packaging materials for potential future transport or warranty claims.
- Physical Placement: Place the miner in a stable, level environment with adequate space for air circulation around the unit, even though it is hydro-cooled. Ensure the location is free from excessive dust and humidity.
- Cooling System Connection:
- Connect the coolant inlet and outlet hoses from your external hydro cooling system to the corresponding ports on the Antminer U3S23Hyd. Ensure connections are secure and leak-free.
- Fill the cooling system with the recommended working coolant (Antifreeze, Pure water, or Deionized water) ensuring the pH value is within the specified range (refer to Specifications).
- Bleed any air from the cooling system according to your external cooling unit's instructions to ensure optimal coolant flow and pressure (8.0-10.0 L/min flow, ≤3.5 bar pressure).
- Power Connection: Connect the miner to a suitable power supply using the provided power cables. The miner requires a 380-415V power source. Ensure your electrical infrastructure can support the 11020W power consumption. Use appropriate circuit breakers and wiring.
- Network Connection: Connect an Ethernet cable from your router or network switch to the Ethernet port on the miner. Ensure a stable internet connection for mining operations.
- Initial Configuration: Power on the miner. Access the miner's web interface via its IP address (usually found using an IP scanner tool on your network). Configure your mining pool settings, worker name, and password as required.
4. Operating Instructions
Once set up, operating the Antminer U3S23Hyd. involves monitoring and occasional adjustments.
- Powering On: After all connections are secure, switch on the power supply to the miner. The miner will initiate its boot sequence.
- Monitoring: Regularly access the miner's web interface to monitor its status. Key metrics to observe include:
- Hashrate: Ensure it is close to the specified 1160TH.
- Temperature: Monitor the operating temperature, which should ideally be within the 20-50 °C range.
- Power Consumption: Verify it is consistent with the 11020W specification.
- Coolant Flow/Pressure: Ensure the hydro cooling system is functioning correctly.
- Powering Off: To safely shut down the miner, first stop mining operations through the web interface if possible, then switch off the power supply.
5. Maintenance
Regular maintenance is essential for optimal performance and longevity, especially for hydro-cooled systems.
- External Cleaning: Periodically clean the exterior of the miner to prevent dust buildup, which can hinder heat dissipation and affect components. Use a soft, dry cloth.
- Coolant System Check:
- Coolant Level: Check the coolant reservoir level regularly and top up as needed.
- Coolant Quality: Monitor the coolant's pH value and clarity. Replace coolant according to the manufacturer's recommendations for your specific cooling fluid to prevent corrosion and buildup.
- Leak Inspection: Regularly inspect all hoses and connections for any signs of leaks. Address any leaks immediately to prevent damage to the miner or surrounding equipment.
- Pump/Radiator Maintenance: Follow the maintenance schedule for your external cooling pump and radiator, including cleaning fins and checking pump operation.
- Firmware Updates: Check the official Bitmain website periodically for firmware updates. Apply updates as recommended to improve performance, stability, or security.
6. Troubleshooting
This section provides solutions to common issues you might encounter.
- Miner Does Not Power On:
- Check all power cable connections.
- Verify the power supply unit (PSU) is functioning correctly and receiving power.
- Ensure the circuit breaker has not tripped.
- Low Hashrate or No Hashrate:
- Check network connectivity; ensure the miner can access the internet and mining pool.
- Verify mining pool settings (URL, worker name, password) are correct in the web interface.
- Check for high temperatures; overheating can cause performance throttling.
- Inspect the cooling system for proper coolant flow and pressure.
- Overheating:
- Ensure the hydro cooling system is operating correctly, with adequate coolant flow and pressure.
- Check coolant levels and quality.
- Verify that the ambient temperature is within the recommended operating range (20-50 °C).
- Ensure there are no blockages in the coolant lines or radiator.
- Network Connection Issues:
- Check the Ethernet cable connection.
- Restart your router/switch.
- Verify the miner's IP address and network settings.
- Error Lights/Indicators: Refer to the miner's specific LED indicators (if any) for diagnostic information. Consult the manufacturer's online resources for detailed explanations of error codes.
