Setup Guide
How to Set Up the
Industrial installation requires professionally prepared electrical and cooling infrastructure. Follow the manufacturer’s manual and use qualified installers; this is not a household plug-and-play setup.

📦 Unboxing
Industrial installation requires professionally prepared electrical and cooling infrastructure. Follow the manufacturer’s manual and use qualified installers; this is not a household plug-and-play setup.
2
🔌 Power Connection
The Antminer S21e Hydro 332T requires a 380-415 V three-phase AC supply and draws 5,644 W continuously. Do not use a single-phase household supply. A qualified electrician must size the supply, breaker and cabling to local code and the manufacturer’s manual. Never share the circuit. This hydro-cooled model also requires a water-cooling loop.
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.

Troubleshooting
Common Issues & Fixes
🚫 Miner Not Turning On
Symptoms
No LEDs, no fan noise after connecting power.
Fix
Do not try other household outlets or improvise wiring. Stop and have a qualified technician check the manufacturer-specified supply, protection devices and cooling system.
🌡️ Overheating / High Temps
Symptoms
Chip temps above 85°C, automatic throttling, warning LED.
Fix
- Improve ventilation — ensure 30cm clearance
- Reduce ambient temperature below 35°C
- Clean dust from heatsinks/fans with compressed air
🌐 Pool Connection Issue
Symptoms
Dashboard shows rejected shares or pool offline. Worker not appearing in pool dashboard.
Fix
- Double-check stratum URL and port number
- Check for typos in worker name
- Try a different pool port (3333, 443, 25)
- Check pool status page for outages
📉 Lower Than Expected Hashrate
Symptoms
Miner hashing significantly below spec (>10% below nominal).
Fix
- Check chip temperatures — overheating causes throttling
- Allow 10+ minutes for pool hashrate to stabilise
- ±5% variance from spec is normal
- Update to latest firmware
