Physical-source conflict
The E9 Pro web specification publishes a 500 mm miner length, while both the English and Chinese manufacturer manuals publish 550 mm. This page uses the manual’s 550 × 195.5 × 310 mm value and visibly preserves the unresolved 500 mm web conflict. Verify the physical unit before planning clearances.
Mandatory dual-input electrical preflight
| Integrated PSU family | APW12; exact sub-model unresolved |
|---|---|
| AC input | 200–240 V AC, 47–63 Hz |
| Maximum current | 20 A under the stated maximum condition: 40°C and 0 m altitude |
| Input arrangement | Two inputs; two AC wires at 10 A each |
| Cords | Two additional cords required; exact type unresolved |
| Network | RJ45 Ethernet 10/100M |
Both power inputs must be connected simultaneously to run. Power off all inputs when shutting down. Use an earthed, readily accessible mains socket-outlet. Wrong voltage can damage the server. A qualified person must verify the exact PSU/inlet/cord labels, both paths, circuit, protection, conductors, disconnecting means, grounding, and local requirements. APW12 family identity does not establish component interchangeability.
Physical, thermal, and environmental boundaries
Exact fan record: four 12038 fans; front and rear 5,200 RPM; 12 V / 2.35 A; 360 CFM mid airflow.
| Manual dimensions | 550 × 195.5 × 310 mm, including PSU |
|---|---|
| Packaged dimensions | 722 × 322 × 427 mm |
| Net / gross weight | 20.2 kg / 22.0 kg, net including PSU |
| Operating frequency | Fixed 500 MHz |
| Thermal firmware boundary | Firmware stops at 80°C outlet temperature |
| Operating / storage temperature | 0–40°C / -20–70°C |
| Operating humidity | 10–90% RH, non-condensing |
| Operating altitude | Up to 2,000 m |
From 900 m to 2,000 m, reduce the highest permitted operating temperature by 1°C for every 300 m increase. The reviewed exact sources do not establish a sound level.
Firmware, diagnostics, and repair
- Record E9 Pro / 260-E and every installed PSU, inlet, cord, connector, and board revision.
- Select E9 Pro and the exact installed revision in Bitmain’s firmware selector.
- Use the official E9 Pro support hub and E9 Pro Server Manual.
- Keep the server powered throughout an upgrade. Bitmain warns that loss of power before completion may require returning it for repair.
- Start with Bitmain’s failure diagnostic guide for power, zero-hashrate, fan, temperature, firmware, control-board, or hashboard-signal symptoms.
- Use the ASIC fault finder to organize symptoms and logs.
- Request ASIC repair diagnosis with exact labels, photographs, logs, symptoms, and prior firmware actions.
- Open the Antminer E9 family hub.
Evidence boundaries: no sound, silicon/controller/board or memory architecture, exact APW12 sub-model, cord/connector type, tuning, third-party firmware, residential/heat/economics, coin-currentness, lifecycle, price, release, compatibility, or cross-algorithm claim is asserted.
