How to Set Up AntMiner S9 (13.5T–14T, 1350W) SHA-256 Bitcoin Miner

The AntMiner S9 is a widely-used SHA-256 ASIC miner capable of delivering 13.5T–14T hash rate with 1350W power consumption. It’s ideal for home or small-scale miners seeking an efficient and reliable Bitcoin mining experience.

This guide provides step-by-step instructions to unbox, connect, configure, and optimize your S9 for maximum performance.

1. Required Equipment

Before starting, ensure you have:

  • AntMiner S9 unit

  • Compatible power supply (PSU) capable of handling 1350W

  • Stable internet connection (Ethernet recommended)

  • Mining pool account (e.g., Antpool, F2Pool, ViaBTC, SlushPool)

  • Computer or mobile device for configuration

  • Adequate cooling and ventilation

  • Surge protector or UPS for power stability

⚠️ Ensure your power source can safely handle 1350W to avoid PSU failure or damage.

2. Unboxing and Inspection

  1. Carefully remove the miner from its packaging.

  2. Inspect for physical damage, including fans, connectors, or casing.

  3. Verify all accessories are included (power cables, screws, manual).

  4. Place the miner on a stable, flat surface with good airflow.

3. Connecting the Power Supply

  1. Connect the PSU to the miner’s input ports.

  2. Ensure the PSU supports 1350W continuous output.

  3. Plug the PSU into a stable electrical outlet, ideally on a dedicated circuit.

  4. Confirm proper grounding to avoid electrical hazards.

💡 Tip: Using a UPS or surge protector helps prevent downtime or damage from power surges.

4. Network Connection

  1. Connect the miner to your router using an Ethernet cable.

  2. Avoid Wi-Fi; Ethernet provides a stable connection for mining.

  3. Ensure DHCP is enabled so the miner receives an IP address automatically.

5. Accessing the Miner Interface

  1. Locate the miner’s IP using your router’s admin panel or the Bitmain IP Reporter tool.

  2. Enter the IP in a web browser.

  3. Log in using default credentials:

    • Username: root

    • Password: root

  4. Navigate to the Miner Configuration page.

6. Mining Pool Configuration

  1. Enter your mining pool URL(s).

    • Example for Antpool: stratum+tcp://btc.antpool.com:3333

  2. Input your Worker Name (usually walletaddress.workername).

  3. Enter a password if required (often “x”).

  4. Save and apply the settings.

Your S9 will begin hashing and submitting shares to the pool.

7. Monitoring Miner Performance

  1. Check the Miner Status page for:

    • Hashrate (should be close to 13.5T–14T)

    • Fan speeds and temperatures

    • Accepted/rejected shares

  2. Adjust cooling if the miner gets too hot.

  3. Enable automatic restart in case of network or power failures.

8. Firmware Updates

  • Regularly check Bitmain’s website for firmware updates.

  • Update via the System tab in the miner interface to improve performance, security, and efficiency.

9. Safety and Maintenance

  • Keep the miner in a cool, dust-free area.

  • Ensure proper airflow to prevent overheating.

  • Check power connections periodically.

  • Avoid overloading your electrical circuit; a dedicated line is recommended for multiple miners.

10. Troubleshooting

  • Miner not powering on: Check PSU and electrical connections.

  • Low hashrate: Verify pool settings, network stability, and firmware version.

  • Overheating: Improve airflow and clean dust from fans.

  • Network issues: Use IP Reporter to reconnect or reset the miner.

Conclusion

The AntMiner S9 remains a reliable, energy-efficient SHA-256 miner for Bitcoin mining. By following this setup guide, you can safely and efficiently run your miner at 13.5T–14T, maximizing uptime and profitability.
