Notes
- The Hashrate value, Power on wall, and Power efficiency on wall are all typical values, The actual Hashrate value fluctuates by ±3%, and the actual Power on wall and Power efficiency on wall fluctuate by ±5%.
- Inlet air temperature.
- Caution: Wrong input voltage may probably cause server damaged.
- Two AC input wires, 10A per wire.
- Caution: It is strongly recommended that the power on wall of the minier does not exceed this value.
- Max condition: Fan is under max RPM(rotation per minute).
- When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.
