Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Bitmain Antminer S19j is a high-performance server designed for cryptocurrency mining, specifically for algorithms compatible with SHA256/BTC/BCH. As the newest iteration in Bitmain's 19 server series, it is engineered for ease of setup, with all units undergoing testing and configuration prior to shipment. The server integrates an APW12 power supply unit, which is an integral part of its design.

Function Description

The primary function of the Antminer S19j is to perform the intensive computational tasks required for cryptocurrency mining. It operates by processing complex algorithms, contributing to the blockchain network and earning cryptocurrency rewards. The server is equipped with multiple hash boards housed within a robust casing, and its operation is managed by a dedicated controller.

The control panel, available in two versions, provides essential interfaces for monitoring and managing the device. Key components include an IP Report Pushbutton, an Ethernet Connector for network connectivity, and a Fault Indicator to signal operational issues. For user interaction, there's a Reset Button and a Normal Operation Indicator. Both control panel versions also feature an SD Card Slot, though their physical appearance may differ. The server's cooling system comprises both front and rear fans, crucial for maintaining optimal operating temperatures during continuous, high-load mining operations.

Powering the device requires connecting two power supply sockets simultaneously, as the equipment has two power inputs. It's critical to ensure both are connected for the server to run. When powering off, all power inputs must be disconnected. The server is designed to be connected to an earthed mains socket-outlet, which should be easily accessible and located near the equipment.

Usage Features

Setting up the Antminer S19j involves a straightforward process. Users begin by downloading and extracting the IPReporter tool, which is compatible with Microsoft Windows. This tool helps in identifying the server's IP address on the network. Once the IP address is obtained by pressing the IP Report button on the controller board, users can access the server's web interface through a browser.

The web interface allows for configuration of mining pools, which are essential for collaborative mining. Users can set up to three mining pools, with a defined priority order. The server will prioritize the first pool and only switch to lower-priority pools if the higher-priority ones become offline. This feature ensures continuous mining operations even if a primary pool experiences downtime. Users can input the mining address, worker ID, and an optional password for each pool.

The server offers two working modes: Normal mode and Sleep mode. In Sleep mode, the control board remains powered, but the hash boards are not, which can be useful for reducing power consumption when full mining capacity is not required. The fan speed percentage can be adjusted, though the default setting is recommended as the server automatically regulates fan speed for optimal cooling.

Monitoring the server's status is facilitated through the dashboard in the web interface. This provides real-time information such as the real-time hashrate, average total hashrate, network status, fan speed, and miner temperature. It also displays the number of chips detected in the chain, ASIC frequency settings, inlet and outlet temperatures, and the state of each chip (indicated by green for normal or red for abnormal). This comprehensive monitoring allows users to quickly assess the server's performance and identify any potential issues.

Maintenance Features

The Antminer S19j incorporates several features for maintenance and administration. Users can check the firmware version of their server through the web interface, which displays the date of the installed firmware. This is important for ensuring the device is running the latest software for optimal performance and security.

Firmware upgrades are a key maintenance feature, allowing users to update their server's software. The upgrade process is initiated through the web interface, where users can upload a new firmware file. It is crucial that the server remains powered throughout the upgrade process; any power interruption before completion may necessitate returning the device to Bitmain for repair. Users have the option to "keep settings" during an upgrade, preserving their current configurations, or to unselect this option to reset the server to default settings.

Password modification is also available through the web interface, allowing users to enhance the security of their server by changing the default login credentials.

For troubleshooting or to revert to a known good state, the server can be restored to its initial factory settings. This is achieved by pressing and holding the Reset button on the controller front panel for 10 seconds after the server has been running for at least 5 minutes. A successful reset is indicated by the red LED flashing automatically every 15 seconds, and it will reboot the server, restoring all default settings.

Environmental requirements are critical for the longevity and stable operation of the Antminer S19j. The server should be operated within specific temperature and humidity ranges, and at altitudes below 2000 meters. For every 300-meter increase in altitude above 900 meters, the highest operating temperature decreases by 1°C. It is also important to keep the server away from industrial pollution sources, such as smelters, chemical industries, and high-power electrical or radio equipment, to prevent harmful interference and maintain air quality. The server running room should be free of explosive, conductive, magnetically conductive, and corrosive dust, with specified limits for sand, suspended dust, and deposited dust. Additionally, the concentration of corrosive gases like H2S, SO2, Cl2, NO2, HF, NH3, and O3 must be kept below defined thresholds to prevent damage to the equipment.
