2.9 Environmental specifications
2.9.1 Ambient temperature
Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual
drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions.
2.9.2 Temperature gradient
2.9.3 Humidity
2.9.3.1 Relative humidity
2.9.3.2 Wet bulb temperature
2.9.4 Altitude
2.9.5 Shock
All shock specifications assume that the drive is mounted securely with the input shock applied at the drive
mounting screws. Shock may be applied in the X, Y or Z axis.
2.9.5.1 Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum
o
perating shock of 70 Gs based on half-sine shock pulses of 2 ms during read operations. Shocks should not be
repeated more than two times per second.
2.9.5.2 Non-operating shock
1000 and 750GB models
The non-operating shock level that the drive can experience without incurring physical damage or degradation in
pe
rformance when subsequently put into operation is 300 Gs based on a non-repetitive half-sine shock pulse of 2
ms duration.
