Inspect all items for any sign of damage during shipping. Check that model numbers match on the miner and power supply. Contact support if any issues. Keep all packaging materials until setup is complete.

Necessary Additional Equipment

To operate the Antminer S19J Pro, you will need:

  • 220V/240V 30A power source
  • Heavy duty PDU power strip
  • Ethernet switch and router
  • Mining pool account
  • Computer for web interface

Procure all additional equipment before placement and installation. Use enterprise-grade networking hardware for best stability.

Location and Environment

Proper placement is crucial for optimizing performance and lifetime of the S19J Pro. Ideal conditions include:

  • Temperature: Under 40°C
  • Humidity: Under 60%
  • Well-ventilated, dust-free room
  • Near dedicated 20-30A circuit power source

Avoid placing in home environments. Excess dust, humidity and heat buildup will throttle performance. Setup in a clean data center or mining farm facility for best results.

Setting Up the Hardware

With all equipment and space ready, begin hardware setup:

  1. Mount miner hardware securely in racks or shelves. Allow 6-12 inches rear clearance.
  2. Connect LAN cable from router to miner Ethernet port.
  3. Plug in the heavy duty PDU power strip nearby.
  4. Connect miner power supply unit to power strip.
  5. Finally, connect power cable to miner power port to complete the hardware setup.

Connecting to Power Supply

Begin powering up the hardware:

  1. Turn on the facility or room circuit breaker for the miner's electrical circuit.
  2. Flip the power switch on the PDU to energize the outlets.
  3. Toggle the power supply unit switch to turn on the miner's power.
  4. The miner will automatically boot up when powered on.
  5. Led lights on the front confirm power status.

Start with powering the miner alone to verify stability initially. Monitor power draw and temps closely at first.

Configuring Network Settings

In order to connect with the miner, LAN network settings must be properly configured:

  1. Ensure the router DHCP server is enabled to assign IP addresses.
  2. Identify the IP address assigned to the miner in the router admin interface.
  3. If needed, you can assign a static IP address manually via the miner's web UI.
  4. Configure port forwarding on the router if remotely accessing the miner over the internet.

Double check cabling and VLAN settings if the miner is not obtaining an IP address as expected. Proper network configuration is critical.

Accessing the Web Interface

With network settings completed, you can now connect to the miner's web UI:

  1. Open a browser on your management computer.
  2. Enter the miner's IP address in the address bar.
  3. Log in with username “root” and the default password “admin”.
  4. You will see the dashboard showing device information and status.

This web interface is vital for configuring, monitoring, and managing the Antminer S19J Pro.

Configuring Mining Pool Settings

Proper setup allows pushing mined blocks to your desired bitcoin mining pool:

  1. Under the “Miner Configuration” menu, select “Mining Settings”.
  2. Enter your preferred mining pool URL, port, username and password.
  3. Scroll down and click Save and Apply to set the pool parameters.
  4. Double check pool account setup before starting actual mining operations.

Successful pool connectivity means steady mining payouts down the road.

Updating Firmware

It is highly recommended to upgrade the S19J Pro firmware for the latest features and security:

  1. In the web UI, go to the Firmware Update page.
  2. Download the latest firmware file from
  3. Select the downloaded file and click Update.
  4. The miner will install the firmware and automatically reboot.

Schedule firmware upgrades for off-peak hours to minimize mining interruption. Keep firmware updated for optimal stability.

Monitoring and Maintaining

Ongoing maintenance is key for maximizing the operational lifetime and profitability of your Antminer S19J Pro:

  • Check temperature and fan speeds using the dashboard.
  • Keep the intake vents free of debris and dust buildup.
  • Regularly reboot and verify configuration settings.
  • Schedule periodic firmware updates.
  • Replace the air filter as needed.
  • Monitor the pool dashboard to validate active mining.
  • Keep ethernet cabling in good condition.
  • Diagnose and address any performance issues promptly.

With proper monitoring and care, your S19J Pro will deliver years of optimized bitcoin mining results.

Tips for Optimal Performance

Follow these tips for keeping your S19J Pro hashing at peak efficiency:

  • Keep the ambient temperature under 30°C.
  • Maintain ventilation and free airflow around the miners.
  • Use enterprise-grade networking hardware for stability.
  • Keep humidity low to avoid condensation inside.
  • Apply updated firmware frequently.
  • Set fan speeds at optimal levels, not 100%.
  • Use the same pool for all your ASICs.
  • Leave space between miners to prevent overheating.
  • Set clocks and voltage to factory settings.
