Common manufacturer-published details are two 12 V fans rated at 2.4 A, front/rear fan speeds of 6,000/4,500 rpm, 0–40°C operation, 5–95% non-condensing surrounding humidity, 76 dB noise, ten PCIe power connectors, three hashboards, 189 chips, 4.2 kg net weight, and dimensions of 350 × 135 × 158 mm.
Electrical boundary
The published 11.6–13 V figure is the miner’s DC input, not a facility AC-input specification. The external PSU determines permissible AC input, circuit loading, cords, connectors, and protection. Confirm the exact PSU model and revision from its physical label and its own manufacturer documentation.
Firmware and recovery
The S9i model name does not identify one universal control board or authorize a particular image. Record the complete miner label, board markings, installed firmware version, visible recovery interface, and failure symptom before firmware or recovery work. A similar connector or slot is not proof of compatibility.
- Identify the exact control-board revision.
- After both model and board match, use the current manufacturer entry and the board-scoped recovery boundary.
- For no boot, missing hashboards, instability, interrupted writing, or electrical or physical damage, request Antminer diagnosis.
Unknown or revision-dependent: the specification page does not establish one universal control-board revision, firmware image, recovery medium, external PSU, facility AC requirement, or present retail configuration.
