Status Evidence-limited identity

Evidence-limited identity record: Bitmain official model, warranty, parts, or power-supply records confirm the exact name Antminer S21e Hyd.. The durable primary material reviewed does not provide a complete standalone specification substantiating the former 288T, 310T, or 332T bin claims.

Former performance, power, efficiency, noise, physical, electrical, cooling, release, price, lifecycle, tuning, firmware, and commercial claims have therefore been withdrawn.

Confirmed evidence boundary

The current manufacturer warranty list confirms S21e Hyd. as a product identity. This evidence confirms identity only within its stated scope. It does not establish hashrate, wall power, efficiency, input topology, coolant or oil requirements, control board, firmware compatibility, recovery medium, or parts interchangeability.

Do not collapse nearby S21 names

Plus signs, the letter “e,” XP, Hyd., Imm., and 3U are part of the hardware identity. Do not transfer a PSU, hashboard, controller, firmware package, recovery image, liquid specification, facility design, or product listing from a similarly named S21 machine.

Evidence required before installation or service

Collect the complete physical nameplate, exact manufacturer document revision, PSU label, input rating and phase, controller marking, cooling connections, and installed version. A reseller title, calculator record, arithmetic inference, or similar chassis image is not adequate evidence.

Run open-source firmware on your Antminer

DCENT_OS is D-Central’s GPL-3.0 Antminer firmware source. Guarded artifacts exist only for exact S9 XIL and S19j Pro XIL lanes; install evidence is incomplete, neither is production-ready, and a bad write can brick hardware.
