Electrical and cooling boundary
This is high-power equipment requiring a qualified installation. Verify the complete model/bin and both miner and PSU nameplates before selecting the circuit, protection, conductors, connector, cord, or ventilation. The 185–285 V AC miner range does not make different plugs, circuits, PSU revisions, or A11-series parts interchangeable.
Firmware and repair
Use only a firmware package selected for the exact A1166 Pro model and hardware revision. Similar model names and shared update utilities do not establish firmware, controller, hashboard, fan, or PSU compatibility.
- Record the exact bin, serial label, hardware revision, and installed version.
- Select A1166 Pro through Canaan’s exact-model picker.
- Use Canaan’s download guidance and FMS, AvalonBuddy, or upgrade-tool guidance only where the package explicitly supports the unit.
- For hardware faults, request A1166 Pro diagnosis.
Known boundaries: no ASIC model/count, universal controller, cross-model parts compatibility, tuning, economics, home-suitability, price, or lifecycle status is asserted.
