-197 to 5906 ft (-60 to 1800 m) at 122°F (50°C), short-term
Up to 13,123 ft (4000 m) at 104°F (40°C) or below
47,408 BTU per hour (maximum) fixed configuration DC2
51,180 BTU per hour—(maximum) fixed configuration AC3
50,042 BTU per hour (maximum) modular configuration DC4
48,955 BTU per hour—(maximum) modular configuration AC5
Air exhaust temperature
129°F (54°C)—at room temperatures of 95 to 102°F (35 to 39°C)
149°F (65°C)—maximum exhaust temperature on a fully loaded system during worst-case operating conditions (50°C and 6000 ft altitude)
Note Air temperature rise is 59°F (15°C) on a fully loaded system with fans running at maximum speed (5150 RPM).
At room temperatures below 95°F (35°C), exhausted air is 66.2°F (19°C) higher than room temperature. At temperatures above 102°F (39°C), exhausted air is 59°F (15°C) higher than room temperature.
Air velocity (at exhaust)
1400 ft per minute (426.7 m per minute) at normal room temperature, low fan speed (4000 RPM)
1800 ft per minute (548.6 m per minute) at high temperature or altitude, maximum fan speed (5150 RPM)
Note Software controls the speed of the fans based on measurements from the chassis thermal sensors.
