Mechanical Specifications Environmental Specifications Environmental Specifications Environmental Specifications (System Processing Unit with Hard Disk) Storage Humidity 90% (relative, non-condensing) Operating Humidity 15% to 80% (relative, non-condensing) Storage Temperature Operating Temperature Altitude Shock Vibration Acoustics -40o C (-40o F) to 70o C (158o F) 5o C (41o F) to 35o C (95o F) • Operating: 0 to 10,000 ft. (3100m) • Non-operating: 0 to 15,000 ft. (4500m) • Operating: Maximum 20 G at less than 3 ms (1/2 sine) • Non-operating: Maximum 80 G at less than 3 ms (1/2 sine) • Operating Random: Maximum 0.21 G (RMS) • Operating Swept-Sine: Maximum 0.5 G (0 - Peak) • Non-Operating Random: Maximum 2.09 G (RMS) • +5 to +25 degrees C: Less than 5.0 Bels (sound power) • +25 to +35 degrees C: Less than 5.5 Bels (sound power) Operating temperature and humidity ranges may vary depending on the installed mass storage devices. High humidity levels can cause improper disk operation. Low humidity levels can aggravate static electricity problems and cause excessive wear of the disk surface. 124 Chapter 8
