Maximum rate of change is 10° C/Hr. The upper limit may be limited by the type and number of options installed. Shock The level of shock the product can withstand with no damage being incurred is 35 G peak input acceleration during an 11-millisecond trapezoidal shock pulse. Vibration Operating Non-operating 5 Hz to 300 Hz (0.25 G nominal 5 Hz to 500 Hz (2 G nominal) NOTE: Listed are the levels of vibration the product can withstand with no damage being incurred. The values represent a flat random vibration input acceleration profile across the given frequency range. Acoustic noise Idle, fixed disk drive spinning DVD-ROM sequential reads LWAd = 43 dB LWAd = 55 dB Desktop average LpAm = 32 dBA Deskside average LpAm = 44 dBA NOTE: Listed are the declared A-weighted sound power levels (LWAd) and declared average desktop seated operator position A-weighted sound pressure levels (LpAm) when the product is operating in a 23°C (73.4°F) ambient environment.
