  1. Select a location for your Antminer(s) that:
    1. Has access to adequate electrical service. A single Antminer S9 typically consumes between 1400 - 1650 watts depending on it’s electrical setup.
    2. Is capable of providing adequate ventilation and cold air. A single Antminer significantly increases a rooms ambient temperature as the chips temperatures can run over 80°C (176°F). If the rooms temperature is allowed to approach and exceed 37°C (100°F), hashing efficiency will degrade and the miners will automatically shut down or restart.
    3. Secure from theft and vandalism. Antminers are valuable electronics and grand theft of the devices is being reported around the world. Be safe and secure your assets.
    4. Able to accommodate extreme noise. A single Antminer can produce up to 90 decibels; roughly the same as a portable gas generator.
  2. Purchase Bitmain Antminers
  3. Bitmain URL in chrome browser.
    1. Select and add Antminers to your cart directly on The Official Bitmain website. At time of writing Bitmain offers:
      1. The Antminer S9 is a 13.5TH/s SHA256 Miner.
      2. The Antminer T9+ is a 10.5TH/s SHA256 Miner.
      3. The Antminer V9 is a 4TH/s SHA256 Miner.
      4. The Antminer L3 is a 504MH/s Scrypt Miner.
      5. The Antminer A3 is a 815GH/s Blake2 Miner.
      6. The Antminer D3 is a 15GH/s X11 Miner.
      7. The APW3++ Power Supply Unit (PSU) powers most Antminers and works on 100V - 240V electrical systems. Most Antminers do not include PSUs.
  4. Setup your Antminer according to the manufacturer's specifications, find manuals and firmware for Bitmain's Antminers at
  5. Attain the Antminer’s IP address. There are a few methods to get the Antminers IP. Such as logging into the local network router as an admin. Using the IP discovery tool provided by Bitmain (only functions on Windows 7 or 8). If those don’t work you can guess by proximity of your computer’s local network IP or try googling other techniques.
    1. Use a computer on the same network as the Antminer.
    2. Access your router’s administrator dashboard by inputting your network’s gateway IP address or the routers default URL into your web browser. (ie. or for Netgear routers, etc.)
    3. Netgear router admin URL.
      1. To find your Gateway IP address using the Windows command prompt type “$ ipconfig | findstr /i "Gateway"”, on the linux terminal type “ip route | grep default” and in MAC OS X type “netstat -nr | grep default”.
      2. Login to your router's administrator dashboard. Check your router's manual for it’s default username and password, which your strongly advised to change.
      3. Admin login for Netgear router.
      4. SECURITY NOTE: Make sure that your router has the most up to date firmware and security patches. It’s also strongly advised to change the default router passwords.
      5. Update Firmware for your router.
        Update your router’s password.
    4. Navigate to your router’s “Attached Devices”.
    5. Identify and copy your wired Antminer’s IP address(es).
    6. Netgears attached devices tab.
  6. Enter and go to the Antminer’s IP address into the web browser.
  7. Antminer’s IP in the web browser.
  8. Upon being prompted for a login and password, enter the default username and password, “root” and “root”. Make sure to update and secure the default login information by visiting the “Administration” tab.
  9. Login popup for an Antminer.
    The Bitman Antminer administration tab to change the password.
  10. Navigate to the Antminer’s “Miner Configuration” tab and input your stratum URLs with port numbers, your workers and random passwords. Then click “Save & Apply”, then wait another 10-15 minutes, while the antminer restarts.
  11. The Bitmain Antminer Miner configuration tab to change the pool URL and worker information.
  12. Navigate to the Antminer’s “Miner Status” tab.
  13. The Bitmain Antminer Miner Status tab to change the password.
    1. Wait. The Antminer takes about 10 - 15 minutes to fully startup. Once completely started up the “Kernel Version” should be displayed on the “Miner Status” tab, instead of a “socket connection error” and the “Load Average” should have 3 positive decimal numbers, one for each chip blade.
    2. Confirm that the Antminer is reporting hashing under the GH/S(RT) and GH/S(avg) column.
    3. Confirm that the Antminer is communicating with the network by displaying “Alive” under the pools status column while also displaying accepted shares.
  14. Monitor and confirm the status of your Antminer’s workers by visiting your workers page.
