2. Safety Information

• High Voltage Warning: This device operates on 220V AC power and will not function on standard residential 110V outlets. Ensure your power source meets the 220V requirement.
• Power Consumption: The miner draws approximately 3400W. Verify your electrical infrastructure can safely support this load.
• Heat Generation: The Antminer L9 generates significant heat during operation. Ensure adequate ventilation to prevent overheating and maintain optimal performance. Do not obstruct air vents.
• Electrical Connections: Always ensure all power connections are secure before powering on the device. Use only the provided power supply and cord.
• Placement: Place the miner on a stable, non-flammable surface, away from moisture, dust, and direct sunlight.

3. Package Contents

Verify that all items are present in your package:

• Bitmain Antminer L9 Unit
• Dedicated Power Supply Unit (PSU)
• P13 to C20 Power Cord

4. Setup

4.1 Power Connection

1. Connect the P13 end of the provided power cord to the Antminer L9 unit.
2. Connect the C20 end of the power cord to the dedicated Power Supply Unit (PSU).
3. Plug the PSU into a 220V AC power outlet. Do not attempt to use a 110V outlet.

4.2 Network Connection

1. Connect an Ethernet cable (RJ45) from your network router or switch to the Ethernet port on the Antminer L9.
2. Ensure your network provides low latency for optimal mining performance.

4.3 Initial Power On

Once power and network are connected, the miner will automatically power on and begin its initialization sequence. The LED display on the unit will indicate its status.

7. Troubleshooting

• Miner Not Powering On:
  • Ensure the power cord is securely connected to both the miner, PSU, and the 220V power outlet.
  • Verify the 220V power source is active and providing sufficient power.
• Overheating Issues:
  • Check that the cooling fans are operating at their specified RPM (6000-7000 RPM).
  • Ensure air intake and exhaust vents are clear of obstructions.
  • Reduce ambient room temperature if necessary.
• Network Connectivity Problems:
  • Verify the Ethernet cable is properly connected.
  • Check your router/switch for network issues.
  • Confirm the miner's IP address and try accessing the web interface again.
• Low Hash Rate:
  • Review network latency and stability.
  • Check for any environmental factors affecting performance (e.g., high temperature).
  • Ensure the power supply is delivering stable power.
