3. Computer or device with a web browser (for accessing the Antminer web interface)
4. The latest firmware update file for the Antminer S21+ (available for download on the Bitmain website)
Downloading the Firmware Update
The first step is to obtain the latest firmware update file for the Antminer S21+. You can find this on the Bitmain website， typically under the “Support” or “Downloads” section. Make sure to download the correct firmware version that is compatible with your specific Antminer model.
Once you have the firmware update file， save it to a location on your computer or device that you can easily access during the update process.
Accessing the Antminer Web Interface
To begin the firmware update， you’ll need to access the Antminer S21+ web interface. Follow these steps:
1. Connect your Antminer S21+ to your local network using the Ethernet cable.
2. Determine the IP address of your Antminer. This is typically displayed on the LCD screen of the device or can be found through your network router’s administration page.
3. Open a web browser on your computer or device and enter the IP address of your Antminer S21+ in the address bar.
4. The Antminer web interface should load， prompting you to enter the login credentials. The default username is “root” and the default password is “admin”.
Initiating the Firmware Update
With the Antminer web interface open， follow these steps to begin the firmware update process:
1. Locate the “System” section in the web interface.
2. Click on the “Firmware Upgrade” option.
3. In the “Firmware Upgrade” page， click on the “Choose File” button and navigate to the firmware update file you downloaded earlier.
4. Once the file is selected， click the “Upgrade” button to start the update process.
The Antminer S21+ will now begin the firmware update process. This may take several minutes， so be patient and do not interrupt the update or power off the device during this time.
Verifying the Firmware Update
After the firmware update is complete， you’ll want to verify that the new firmware version has been successfully installed. Follow these steps:
1. Refresh the Antminer web interface to ensure the page has been updated.
2. Locate the “System” section again and check the “Firmware Version” information. This should now display the new firmware version you just installed.
3. Alternatively， you can check the LCD screen of the Antminer S21+， which should also display the updated firmware version.
Congratulations! You have now successfully installed the latest firmware update on your Antminer S21+. This process helps ensure that your mining rig is operating at peak efficiency and security， maximizing your returns and protecting your investment.
