Unit Environment and Operating Conditions
General Unit Operating Guidelines
Keep the computer away from excessive moisture, direct moisture and the extremes of heat and cold, to ensure that unit
is operated within the specified operating range.
Leave a 10.2 cm (4 in) clearance on all vented sides of the computer to permit the required airflow.
Never restrict airflow into the computer by blocking any vents or air intakes.
Do not stack computers on top of each other or place computers so near each other that they are subject to each other's
re-circulated or preheated air.
Occasionally clean the air vents on the front, back, and any other vented side of the computer. Lint, dust and other
foreign matter can block the vents and limit the airflow.
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be provided on the
enclosure, and the same operating guidelines listed above will still apply.

Non-operating: –22° to 140° F(–30° to 60° C)
Relative Humidity
Operating: 10% to 90% (non-condensing at ambient)
Non-operating: 5% to 95% (non-condensing at ambient)
Maximum
Altitude (unpressurized)
Operating: 10,000 ft (3048 m)
Non-operating: 30,000 ft (9144 m)
*Operating temperature is de-rated 1.0 deg C per 300 m (1000 ft) to 3000 m (10,000 ft) above sea level, no direct sustained
sunlight. Maximum rate of change is 10 deg C/Hr. The upper limit may be limited by the type and number of options installed.
