Key features include:
- High Hash Rate: Achieves a total hash rate of 14.00 TH/s, distributed across three hash boards, each containing 63 hash chips.
- Efficient Power Consumption: Designed for optimal power efficiency with a rating of 94 J/TH + 10%.
- Robust Cooling: Features an air cooling method to maintain optimal operating temperatures.
2. Setup and Installation
Follow these steps to properly set up your Antminer S9i:
- Unpacking: Carefully remove the Antminer from its packaging. Inspect for any visible damage.
- Power Connection: The device requires power to all three PCI-E ports on the hash boards. It is recommended to power the control board before connecting power to the hash boards. You can use one Power Supply Unit (PSU) to power several boards, but avoid powering a single board with two PSUs.

- Placement: Place the Antminer in a well-ventilated area to ensure proper airflow for cooling. The operating temperature range is 0 to 40°C.
3. Operating Instructions
Once the Antminer S9i is powered on and connected to the network, it will begin its initialization process. You can typically access the miner's web interface via its IP address to configure mining pools and monitor performance.
- Hash Rate: The device is designed to achieve a hash rate of 14.00 TH/s.
- Power Specifications:
- DC Voltage Input: 11.60 to 13.00V
- DC Input Current (at 12V): 102.3 A +10%
- DC Input Power (at 12V): 1228 W +10%
- 220VAC Power @25°C, 93% conversion efficiency of APW3: 1320 W +10%
- Noise Level: The typical noise level during operation is 76 dB. Consider this when choosing a location for the miner.

4. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your Antminer S9i:
- Environmental Conditions:
- Storage Temperature: -40 to 85°C
- Operation Humidity: 5%RH-95%RH (non-condensing)
- Dust Removal: Periodically clean the fans and heatsinks to prevent dust buildup, which can impede airflow and lead to overheating. Use compressed air for best results.
- Cable Management: Ensure all power and network cables are securely connected and not obstructing airflow.
5. Troubleshooting
If you encounter issues with your Antminer S9i, consider the following:
- No Power:
- Verify that all three PCI-E power connectors are securely plugged into the hash boards and the control board is powered.
- Ensure the Power Supply Unit (PSU) is functioning correctly and providing adequate power.
- No Network Connection:
- Check the Ethernet cable connection to both the miner and your network device.
- Confirm your network router/switch is operational.
- Observe the network indicator lights on the control board (refer to Figure 3).
- Low Hash Rate:
- Ensure the miner is operating within the recommended temperature range (0 to 40°C). Overheating can lead to performance degradation.
- Check for dust buildup on fans and heatsinks.
- Verify mining pool configuration and internet connectivity.
- Physical Condition: Minor scratches and rust on the surface do not typically affect the functionality of the device. All hash boards are tested to ensure they are in good working condition before shipment.
