Notes:
\r\n\r\n(1-1) 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%.
\r\n\r\n(1-2) Inlet air temperature.
\r\n\r\n(2-1) Caution: Wrong input voltage may probably cause server damaged.
\r\n\r\n(2-2) The noise is loudest when the fan is under maximum RPM(rotation per minute).
\r\n\r\n(2-3) When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.
