7.4 Environmental limits
Temperature and humidity must not cause condensation within the drive.
Altitude and atmospheric pressure specifications are referenced to a stan-
dard day at 58.7°F (14.8°C). Maximum wet bulb temperature is 79°F (26°C).
7.4.1 Temperature
a. Operating
The MTBF specification for the drive is based on operating at a local
ambient temperature of 95°F (35°C). Occasional excursions to drive
ambient temperatures of 113°F (45°C) may occur without impact to the
specified MTBF. The enclosure for the drive should be designed such that
the temperatures at the locations specified in Section 6.2.2 are not
exceeded. Air flow may be needed to achieve these temperatures.
Continual or sustained operation at case temperatures above these
values may degrade MTBF.
The drive meets all specifications within a 50° to 113°F (10° to 45°C)
drive ambient temperature range with a maximum gradient of 36°F
(20°C) per hour.
b. Non-operating
Non-operating temperature should remain between –40° to 140°F (–40°
to 60°C) package ambient with a maximum gradient of 36°F (20°C)
per hour. This assumes that the drive is packaged in the shipping
container designed by Seagate.
7.4.2 Relative humidity
The values below assume that no condensation on the drive occurs.
a. Operating
5% to 95% relative humidity with a maximum gradient of 10% per hour
b. Non-operating
5% to 95% relative humidity
7.4.3 Effective altitude (sea level)
a. Operating
–1,000 to
+
6,000 feet (–305 to
+
1,829 meters)
b. Non-operating
–1,000 to
+
40,000 feet (–305 to
+
12,210 meters)
7.4.4 Shock and vibration
Shock and vibration limits are measured directly on the drive’s chassis.
Ensure that you use an enclosure that buffers and restricts the drive’s
movements to meet the shock and vibration requirements listed below.
The limits of shock and vibration defined within this manual are specified
with the drive mounted in one of the two methods shown in Figure 10.
