Step 2: Connect to the Internet
- Plug one end of the Ethernet cable into the miner.

The Antminer S21 XP does not support Wi-Fi, so a wired connection is required for stable mining performance.
Step 3: Power On the Miner
Once power and internet are connected:
- Turn on the PSU.
- The miner’s fans will start spinning loudly — this is normal.
- Wait 1–2 minutes for the system to boot.

Step 5: Log Into the Miner Dashboard
- Open a browser on your computer.
