Environmental and Mechanical Screening

The following list details the environmental specifications.

• Temperature:

  • Operating: ASHRAE Class A4: 5°C to 45°C. The maximum ambient temperature decreases by 1°C for every 125 m (410 ft) increase in altitude above 900 m (2,953 ft).

  • Board off: 0°C to 60°C

  • Shipment and storage: -40°C to 85°C

• Maximum altitude: 3,050 m (10,000 ft)

• Relative humidity (non-condensing):

  • Operating: ASHRAE Class A4: 8% to 95%; maximum dew point: 45°C

  • Shipment and storage: 8% to 95%

  • Non-operating (unpacked) storage: 5% to 95% at 45°C maximum dry-bulb temperature for 48 hrs.

• Vibration and shock values - board operation

  • Shock: 40 G, 6ms, half-sine, ±X, ±Y, ±Z

  • Shock: 30 G, 11ms, half-sine, ±X, ±Y, ±Z

  • Vibration: 3.0 G rms, 3-500 Hz, 60 mins/axis

• Non-operation vibration data is as follows:

  • Single board: 7.7 G rms at 20 - 2000 Hz for 60 minutes across 6 surfaces

• Non-operation shock data is as follows:

  • Single board: 50 G for 11ms, square wave, in each direction (±X, ±Y, ±Z axes)
