Chassis environmental specifications Specification Value Temperature range* Operating Non-operating - 10°C to 35°C (50°F to 95°F) -30°C to 60°C (-22°F to 140°F) Maximum Wet bulb temperature Operating - 28ºC (82.4ºF) Non-operating 38.7ºC (101.7ºF) Relative humidity (noncondensing)** - Operating Non-operating 10% to 90% 5% to 95% * All temperature ratings shown are for sea level. An altitude derating of 1°C per 304.8 m (1.8°F per 1000 ft) to 3048 m (10,000 ft) is applicable. No direct sunlight allowed. Upper operating limit is 3,048 m (10,000 ft) or 70 kPa/10.1 psia. Upper non-operating limit is 9,144 m (30,000 ft). ** Storage maximum humidity of 95% is based on a maximum temperature of 45°C (113°F). Altitude maximum for storage corresponds to a pressure minimum of 70 kPa (10.1 psia). Rack and accessory footprints When accessories such as extensions and stabilizing kits are added to a particular rack, the footprint of the rack extends into the rack rear row and infringes upon necessary clearances. Footprint for a 600 mm rack configuration with an extension kit installed (598 mm wide x 1184.9 mm deep): Environmental requirements 14
