Setup Guide
How to Set Up the
From unboxing to first hash in under 30 minutes.
1
📦 Unboxing
Your Canaan Avalon Nano 3S 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
The Canaan Avalon Nano 3S draws 140 W from the supplied manufacturer adapter (28 V DC). Plug that adapter into an ordinary household wall socket and use only that adapter. For information only: 140 W / 28 V is approximately 5 A on the DC side, not the mains input current. Follow the adapter’s stated AC input range and the manufacturer’s instructions.
3
🌐 Network Setup
Connect via WiFi (Ethernet via USB-to-LAN adapter, not included). 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 around the miner. At 33–36 dB, it is very quiet — virtually any room is fine. Avoid enclosed spaces without airflow.
