Latest Generation Hardware
This is a newer generation of mining hardware using recent ASIC chip technology. Compare efficiency, hashrate, and power draw against older generations before choosing a deployment plan.
Lower J/TH means lower electricity cost per unit of hashrate. Compare efficiency alongside purchase cost, noise, voltage, firmware support, and current network difficulty.

Electrical and acoustic requirements
The official input is 220–277 V AC single phase, 50–60 Hz and 20 A, with a 4,000 W adapted AC-output requirement. The product manual publishes 76 dBA at maximum fan speed. Treat this as industrial equipment and validate the actual electrical and acoustic environment.
Physical and environmental reference
The server is 449 × 219 × 293 mm and 18.7 kg net. Packaged dimensions are 640 × 360 × 450 mm and gross weight is 21.5 kg. Network access is RJ45 Ethernet.
The official operating range is −20–45°C, storage is −20–70°C, relative humidity is 10–90% non-condensing, and altitude is up to 2,000 m. Maximum operating temperature derates by 1°C per 300 m above 900 m.
Exact-name boundary
S21 XP is distinct from S21, S21 Pro, S21+, S21 XP Hyd., and S21 XP Imm. Cooling suffixes are not packaging options and do not share facility or firmware assumptions.
Firmware and recovery
The official S21 XP support hub provides general upgrade, reload, and reset navigation, but the reviewed board-selection matrix does not establish a controller-specific S21 XP image. Do not infer a recovery medium or cross-flash route.
- Identify the complete label, board, and installed version.
- Use only the exact current manufacturer support/download entry.
- For no boot, package mismatch, interrupted writing, instability, or electrical and thermal symptoms, request Antminer diagnosis.
