Environmental specifications
2.9.1
Drive 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.
2.9.2
Temperature gradient
Operating:
20°C per hour (68°F per hour max), without
condensation
Nonoperating:
30°C per hour (86°F per hour max)
2.9.3
Humidity
2.9.3.1
Relative humidity
Operating:
5% to 90% noncondensing (30% per hour max)
Nonoperating:
5% to 95% noncondensing (30% per hour max)
2.9.3.2
Wet bulb temperature
Operating:
37.7°C (99.9°F max)
Nonoperating:
40.0°C (104°F max)
2.9.4
Altitude
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.)
2.9.5
Shock
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.
2.9.5.1
Operating 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.
Operating (Drive case temperature)
0° to 70°C (32° to 158°F)
Nonoperating (Drive case temperature)
–40° to 70°C (–40° to 158°F)
