3. Setup Guide

1. Unpacking: Carefully remove the Antminer S19Kpro 120Th from its packaging. Inspect for any signs of damage during transit.
2. Placement: Place the miner on a stable, flat surface in a well-ventilated area. Ensure there is at least 20 cm of clear space around all sides for proper airflow.
3. Power Connection:
   • Connect the power supply unit (PSU) to the miner using the provided cables.
   • Ensure the power source provides a stable 220V supply.
   • Plug the PSU into a grounded power outlet.
4. Network Connection: Connect an Ethernet cable from your router or network switch to the Ethernet port on the miner.
5. Initial Power On: Once all connections are secure, switch on the power button on the miner. The indicator lights should illuminate.
6. IP Address Configuration:
   • Use an IP scanner tool on your network to find the miner's assigned IP address.
   • Alternatively, some miners have a default IP or a button to broadcast their IP. Refer to the specific Bitmain documentation for detailed IP discovery methods.
7. Web Interface Access: Open a web browser and enter the miner's IP address to access its web management interface.
8. Login: Enter the default username and password (typically 'root' for both, or as specified in Bitmain's general Antminer documentation). Change these credentials immediately after the first login for security.

4. Operating Instructions

1. Pool Configuration:
   • Navigate to the 'Miner Configuration' or 'Pool Settings' section in the web interface.
   • Enter the URL, Worker Name, and Password for your chosen mining pool. It is recommended to configure at least two backup pools.
2. Saving Settings: After entering the pool information, save the settings. The miner will automatically restart or begin mining shortly.
3. Monitoring Performance:
   • Access the 'Miner Status' or 'Dashboard' page to monitor the miner's hash rate, temperature, and fan speed.
   • Ensure the hash rate is stable and close to the advertised 120 TH/s.
   • Monitor temperatures to ensure they remain within safe operating limits (typically below 80°C for hash boards).
4. Firmware Updates: Periodically check the official QIO TECH or Bitmain website for firmware updates. Updating firmware can improve performance and stability. Follow the provided instructions carefully when updating.

5. Maintenance
