The provided document is a service manual for the MinerVa MV7, a mining device manufactured by Raft.Global. This manual focuses on troubleshooting and provides detailed information about the miner's components, operation, and maintenance.
Function Description:
The MinerVa MV7 is a cryptocurrency mining machine designed to participate in mining pools. Its primary function is to perform computational tasks required for cryptocurrency mining, contributing to the network and earning rewards. The device is equipped with a control panel that allows for basic interaction and status monitoring, and it connects to a network via an Ethernet port to communicate with mining pools. It operates by continuously performing hashing operations, and its performance is indicated by a hashrate.
Important Technical Specifications:
While specific numerical technical specifications like power consumption, hash rate capacity, or dimensions are not explicitly listed in the provided excerpts, the manual does highlight several functional and interface specifications:
- Ethernet Port: Supports a 100 Mbit Ethernet connection, essential for network connectivity and mining pool communication.
- Power Connection: Uses a C20 socket for the power cable, requiring a C19 plug.
- Cooling: Features two large fans for cooling, which are critical for maintaining optimal operating temperatures and preventing overheating.
- Firmware: The device runs on firmware, with the example version shown as
minerva_mv7_clover_20210823. Firmware upgrades are possible through the web interface.
- Login Credentials: The default login for the miner's web interface is "admin" (case sensitive).
- Mining Pool Address Format:
stratum+tcp://[pool address]:[port number] (e.g., stratum+tcp://eca.ss.greatpool.ca:1800).
- Worker Name Format:
[account name].[worker name] (e.g., MinervaLab.default1).
Usage Features:
The MinerVa MV7 offers several features for user interaction and management:
- Control Panel: Located on the device, it includes:
- IP Report button: Used to broadcast the miner's IP address to the local network, aiding in discovery.
- Reset button: Allows restoration of the miner to factory settings by pressing and holding for 10-12 seconds while the miner is running.
- Red indicator light: Illuminates or flashes to indicate special events, errors, hashboard faults, or fan failures. It also lights up when the IP report or reset button is pressed.
- Green indicator light: Indicates the normal state of the mining machine. It flashes at regular intervals when operational and can be solid during startup or reset.
- Ethernet port: For network connection.
- SD card slot: Primarily for factory use or professional repair; users are warned against inserting SD cards to prevent damage or machine failure.
- Web Interface: The primary method for managing the miner, accessible via its IP address. Key functionalities include:
- Rebooting the Miner: A dedicated "Reboot" page allows for easy restarting of the device.
- Configuring Mining Pools: Users can add, modify, or delete mining pool URLs, worker numbers, and passwords. The miner automatically restarts with new configurations.
- Monitoring Status: The "Status" page provides an overview of the miner's operation, including real-time and average hashrate, reject rate, acceptance rate, network status (ms), fan status, and miner temperature. It also displays the current pool details.
- Firmware Upgrade: A "Upgrade" section allows users to upload new firmware files (with a ".bin" extension) to update the miner's software.
- IP Address Discovery: Multiple methods are provided to find the miner's IP address:
- Viewing the router's DHCP server or web interface.
- Using the "IP Report button" in conjunction with Miner Manager software on a computer within the same local area network.
- Utilizing third-party network scanning software like Advanced IP Scanner.
Maintenance Features:
The manual outlines several troubleshooting and maintenance steps:
- Quick Troubleshooting Checklist: A series of initial checks to resolve common issues before contacting support:
- Power cycling the device.
- Checking for overheating if the miner restarts unexpectedly.
- Verifying power cable connections.
- Ensuring fans are spinning.
- Interpreting LED indicator lights for errors.
- Confirming Ethernet connection and internet access.
- Verifying login credentials for the web interface.
- Checking mining pool addresses and worker names for correctness.
- Confirming connection to the mining pool via the pool dashboard or miner's web interface.
- Restoring to Original Settings: The reset button on the control panel allows users to revert the miner to its factory default configuration.
- Firmware Upgrades: The web interface facilitates updating the miner's firmware, which can be a maintenance step to improve performance or fix bugs. Users are cautioned against powering off the miner during an upgrade to prevent failure.
- Support Contact: If problems persist, users are advised to contact
servicedesk@lakeparime.com with a detailed description of the issue.
The manual emphasizes safety precautions throughout and warns against using SD cards in the dedicated slot or using firmware from unknown sources, as these actions could damage the device. It also notes that the last running mining pool cannot be deleted from the configuration.
