(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%. (1-2) Inlet air
temperature. (2-1) Caution: Wrong input voltage may probably cause server
damaged. (2-2) The noise is loudest when the fan is under maximum RPM(rotation
per minute). (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.
