2.9Environmental 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.

Operating:	0° to 60°C (32° to 140°F)
Non-operating:	–40° to 70°C (–40° to 158°F)

2.9.2 Temperature gradient

Operating:	20°C per hour (68°F per hour max), without condensation
Non-operating:	30°C per hour (86°F per hour max)

2.9.3 Humidity

2.9.3.1Relative humidity

Operating:	5% to 95% non-condensing (30% per hour max)
Nonoperating:	5% to 95% non-condensing (30% per hour max)

2.9.3.2Wet bulb temperature

Operating:	37.7°C (99.9°F max)
Non-operating:	40°C (104°F max)

2.9.4 Altitude

Operating:	–304.8 m to 3,048 m (–1000 ft. to 10,000+ ft.)
Non-operating:	–304.8 m to 12,192 m (–1000 ft. to 40,000+ ft.)

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.

2.9.5.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating 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.

2.9.5.2Non-operating shock

1000 and 750GB models

The non-operating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 300 Gs based on a non-repetitive half-sine shock pulse of 2 ms duration.
