Environment Requirements

• Operation Temperature: 0~45°C
• Storage Temperature: -20~70°C
• Operation Humidity (no condensation): 10%~90% RH
• Operation Altitude: 2000m (temperature decreases by 1°C for every increase of 300m)

Notes

1. NEM: Normal Energy Mode; HEM: High Energy Mode.
2. The Hashrate value, Power on the wall, and Power efficiency on the wall are all typical values,
3. The actual Hashrate value fluctuates by + 3%, and the actual Power on the wall and Power efficiency on the wall fluctuate by £5%.
4. Inlet air temperature.
5. Caution: Wrong input voltage may probably cause server damage.
6. The noise is loudest when the fan is under maximum RPM(rotation per minute).
7. When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1°C for every increase of 300m.

Installation Guide

Safety Precautions

• Ensure you’re operating in an environment with temperatures between 0°C and 45°C and humidity levels between 10% and 90% (non-condensing).
• The T21 requires a three-phase AC power supply with an input voltage range of 380V to 415V. Using a voltage outside this range can damage the miner.

Setup Steps

• Positioning: Place the miner on a flat, stable surface in a well-ventilated area to ensure optimal cooling.
• Power Connection: Connect the miner to the appropriate power source using the provided power cables. Ensure the power supply unit (PSU) is securely connected to the miner.
• Network Connection: Use an Ethernet cable to connect the miner to your network via the RJ45 Ethernet port.
• Configuration: Access the miner’s user interface through your web browser by entering the miner’s IP address. Configure your mining pool settings and other parameters as needed.

FAQs

What should I do if the miner’s hash rate is lower than expected?

• Potential Causes:
  • Unstable network connection.
  • Interference or unstable power supply.
  • Faulty cables or connections.
  • Issues with hashboards or chips.
• Solutions:
  • Replace or check the network cable and ensure a stable internet connection.
  • Ensure proper grounding and consider replacing the power supply if necessary.
  • Reinsert or replace any faulty cables.
  • If hardware issues are suspected, contact Bitmain support for repair services. support.bitmain.com

The miner restarts automatically or has an unstable hash rate. What could be the issue?

• Potential Causes
  • Interference or unstable power supply.
  • Low or unstable voltage.
  • Unstable chips or a damaged control board.
  • Network instability.
• Solutions:
  • Ensure proper grounding and consider replacing the power supply.
  • Consult an electrician to troubleshoot voltage issues.
  • If hardware issues are suspected, contact Bitmain support for repair services.
  • Check the network connection and consult with your network provider if necessary. support.bitmain.com

The miner cannot connect to the mining pool. What steps should I take?

• Potential Causes:
  • Incorrect configuration settings.
  • Network issues.
  • Mining pool server problems.
• Solutions:
  • Restore the miner to factory settings and reconfigure.
  • Check your network connection or contact your internet service provider.
  • Try connecting to a different mining pool to see if the issue persists.
