Environmental specifications

All temperature ratings shown are for sea level. An altitude derating of 1.0°C per 304.8 m (1.8°F per 1,000 ft) to 3,048 m (10,000 ft) is applicable. No direct sunlight allowed. Maximum rate of change is 20°C per hour (36°F per hour).

All temperature ratings shown are for sea level. Good for 40°C operation up to 1,828 m (6,000 ft) with no altitude de-rating. No restriction on product configurations. Abnormal configurations, allowed for up to 96 hours at one time, no more than 15 days maximum per year. Operation above 40°C (104°F) up to 55°C (131°F), no altitude de-rating, 1,828 m (6,000 ft) limit. Some components could be outside the thermal maximum limits. System must be kept running, processor throttling is allowed. Abnormal conditions allow for operation down to -5°C (23°F).

All temperature ratings shown are for sea level. An altitude derating of 1.0°C per 125 m (1.8°F per 410 ft) to 900 m (2,953 ft) is applicable. No direct sunlight allowed. Maximum rate of change is 20°C per hour (36°F per hour). No restrictions on product configurations except for rotating hard drives. PCI cards must be rated for continuous operation with 60°C cooling air. Not rated for operation over 3,030 m (10,000 ft).
