Step-by-Step Guide to Changing Power Settings

The Antminer S21+ is equipped with an intuitive interface that makes adjusting power settings straightforward. Here’s a detailed guide to help you navigate the process:

Step 1: Access the Miner’s Web Interface

1. Connect to the Miner: Ensure your Antminer S21+ is powered on and connected to your local network via Ethernet.
2. Find the IP Address: Use your router’s admin panel or a network scanning tool to locate the miner’s IP address.
3. Log In: Open a web browser and enter the miner’s IP address. Use the default credentials (usually root for both username and password) to log in.

Step 2: Navigate to the Power Settings

1. Dashboard Overview: Once logged in, you’ll see the miner’s dashboard, which displays real-time data such as hashrate, temperature, and power consumption.
2. Go to Configuration: Look for the “Configuration” or “Settings” tab in the menu. This is where you can adjust various operational parameters.

Step 3: Adjust Power Consumption

1. Power Mode Selection: The Antminer S21+ typically offers multiple power modes, such as Low Power, Normal, and High Performance. Select the mode that aligns with your goals:

• Low Power: Reduces energy consumption and heat output but may slightly lower the hashrate.
• Normal: Balances performance and efficiency, ideal for most operations.
• High Performance: Maximizes hashrate but increases power usage and heat generation.

1. Custom Settings: For advanced users, there may be an option to manually set the power limit. Enter a value (in watts) that suits your requirements.

Step 4: Save and Apply Changes

1. Save Configuration: After making adjustments, click “Save & Apply” to implement the new settings.
2. Monitor Performance: Return to the dashboard to observe how the changes affect the miner’s performance. Keep an eye on metrics like hashrate, temperature, and power consumption.

Step 5: Test and Optimize

1. Run Tests: Allow the miner to operate under the new settings for a few hours to assess stability and performance.
2. Fine-Tune: If necessary, revisit the power settings to make further adjustments. The goal is to find the optimal balance between efficiency and performance.

Practical Tips for Optimizing Power Settings

While the above steps provide a basic framework, here are some additional tips to help you get the most out of your Antminer S21+:

1. Understand Your Electricity Costs: If electricity is expensive in your area, prioritize energy efficiency by using the Low Power mode or setting a conservative power limit.
2. Monitor Environmental Conditions: In hot climates, reducing power consumption can help prevent overheating and extend the miner’s lifespan.
3. Leverage Remote Monitoring: Use Bitmain’s official app or third-party tools to monitor your miner remotely and make adjustments as needed.
4. Regular Maintenance: Keep the miner clean and ensure proper ventilation to maintain optimal performance, especially when running at higher power settings.
5. Stay Updated: Firmware updates from Bitmain can introduce new features or optimizations. Regularly check for updates to keep your miner running at its best.
