Setup Guide
How to Set Up the Antminer S21e Hydro 332T
From unboxing to first hash in under 30 minutes.
1
📦 Unboxing
Your Antminer S21e Hydro 332T arrives with the miner unit, power cable, and documentation. No tools required. Inspect for shipping damage and ensure all connectors are seated firmly before powering on.
2
🔌 Power Connection
Connect the power cable. The Antminer S21e Hydro 332T requires 380-415V AC (3-phase) and draws 5644W. Use a dedicated circuit for safe continuous operation.
3
🌐 Network Setup
Connect via Ethernet RJ45. The miner gets an IP via DHCP automatically. Find its IP in your router DHCP client list, then open that IP in your browser to access the dashboard.
4
🏊 Configure Pool
Log into the miner dashboard (default: root/root — change this immediately). Go to Pool Configuration and enter your pool stratum address and wallet/worker name. Set a backup pool for redundancy.
5
🔊 Ventilation
Ensure at least 20–30cm clearance. Best suited for a dedicated space. Avoid enclosed spaces without airflow.
Troubleshooting
