drive activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the drive accepts all commands and returns to Active mode when disc access is necessary.

2.9Environmental specifications

2.9.1Ambient 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 for standard models. Recommended measurement locations are shown in Figure 6.

Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 44°C (112°F) at 10,000 feet (3,048 meters).

Operating:	0° to 60°C (32° to 140°F)

Nonoperating:	–40° to 70°C (–40° to 158°F)

2.9.2Temperature gradient

Operating:	20°C per hour (68°F per hour max), without condensation

Nonoperating:	30°C per hour (86°F per hour max)

2.9.3Humidity

2.9.3.1Relative humidity

Operating:	5% to 90% noncondensing (30% per hour max)

Nonoperating:	5% to 95% noncondensing (30% per hour max)

2.9.3.2Wet bulb temperature

Operating:	37.7°C (99.9°F max)

Nonoperating:	40°C (104°F max)

2.9.4Altitude

Operating:	–60.96 m to 3,048 m (–200 ft. to 10,000+ ft.)

Nonoperating:	–60.96 m to 12,192 m (–200 ft. to 40,000+ ft.)

2.9.5Shock

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 63 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second.
