2.9Environmental specifications

2.9.1Drive case temperature

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

Drive case temperature should be measured at the location indicated in Figure 4 on page 21.

Operating (Drive case temperature)	0° to 70°C (32° to 158°F)
Nonoperating (Drive case temperature)	–40° to 70°C (–40° to 158°F)

Nonoperating:	40.0°C	(104°F max)

2.9.4Altitude

Operating:

Nonoperating:

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

–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 mount- ing screws. Shock may be applied in the X, Y or Z axis.

2.9.5.1Operating shock

The 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 milliseconds. Shocks should not be repeated more than two times per second. For the 2TB model, the maximum operating shock is 80 Gs based on a half-sine shock pulses of 2 milleseconds.
