4.4 Tatarajah Awal
After connecting power and network, power on the miner. You will typically access the miner's web interface via its IP address to configure mining pool settings, worker names, and passwords. Refer to the official BITMAIN documentation or support resources for detailed instructions on accessing and configuring the web antara muka.
5. Operasi
5.1 Starting the Miner
Once configured, the miner will automatically begin the mining process. Monitor the status indicator lights on the control board. A 'Normal' light indicates proper operation, while a 'Fault' light suggests an issue.
5.2 Pemantauan Prestasi
Regularly check the miner's performance through its web interface or your chosen mining pool dashboard. Key metrics to monitor include hashrate, temperature, and fan speed. Ensure these values remain within acceptable operating ranges.
5.3 Algorithm and Cryptocurrency
The Antminer L7 is designed to mine cryptocurrencies that utilize the Scrypt algorithm, primarily Litecoin (LTC) and Dogecoin (DOGE). It can mine both simultaneously, contributing to a diversified mining output.
6. Penyelenggaraan
6.1 Pembersihan
Periodically clean the miner to prevent dust buildup on fans and heatsinks, which can impede cooling efficiency. Use compressed air to gently remove dust from the exterior and fan blades. Ensure the miner is powered off and unplugged before cleaning.
