The bare server is 450 × 219 × 293 mm and 20 kg net. Packaged dimensions are 680 × 390 × 450 mm and gross weight is 22 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 Pro, S21, S21+, and S21 XP are separate exact identities. Similar chassis, performance, or an S21 prefix does not establish the same PSU, controller, hashboard, firmware, recovery image, or parts fitment.
Firmware and recovery
The reviewed factory-firmware board-selection matrix does not list an S21 model. Do not invent a model-wide controller, recovery medium, or lock claim.
- Identify the exact board and installed version.
- Use only the exact current manufacturer support entry after identity is resolved.
- For no boot, package mismatch, interrupted writing, instability, or electrical and thermal symptoms, request Antminer diagnosis.
