ST15150N/ND/W/WD/WC/DC Product Manual, Rev. D 37 7.4.3 Effective altitude (sea level) a. Operating -1,000 to +10,000 feet (-305 to +3,048 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 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 18. 7.4.4.1 Shock a. Operating in a normal environment The drive as installed for normal operation operates error free while subjected to intermittent shock not exceeding: 2.0 Gs at a maximum duration of 11 msec (half-sinewave) Shock may be applied in the X, Y, or Z axis. b. Operating in an abnormal environment The drive as installed for normal operation does not incur physical damage while subjected to intermittent shock not exceeding: 10 Gs at a maximum duration of 11 msec (half-sinewave) Shock occurring at abnormal levels may degrade operating performance during the abnormal shock period. Specified operating performance continues when normal operating shock levels resume. Shock may be applied in the X, Y, or Z axis. Do not apply shock more than two times per second. c. Non-operating The limits of non-operating shock apply to all conditions of handling and transportation. This includes both isolated drives and integrated drives. The drive does not cause drive damage or performance degradation while subjected to non-repetitive shock not exceeding: 50 Gs at a maximum duration of 11 msec (half-sinewave) Shock may be applied in the X, Y, or Z axis. d. Packaged The drive as packaged by Seagate for general freight shipment withstands a drop test against a concrete floor or equivalent with specifications not exceeding: 20 pounds (8.95 kg) for pack's gross weight 48 inches (1,070 mm) for distance dropped Drop test applies to a single or multiple drive pack.

Shock and vibration
Shock and vibration limits are measured directly on the drive 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 18.
7.4.4.1
Shock
a.
Operating in a normal environment
The drive as installed for normal operation operates error free while
subjected to intermittent shock not exceeding:
2.0 Gs at a maximum duration of 11 msec (half-sinewave)
Shock may be applied in the X, Y, or Z axis.
b.
Operating in an abnormal environment
The drive as installed for normal operation does not incur physical
damage while subjected to intermittent shock not exceeding:
10 Gs at a maximum duration of 11 msec (half-sinewave)
Shock occurring at abnormal levels may degrade operating performance
during the abnormal shock period. Specified operating performance
continues when normal operating shock levels resume.
Shock may be applied in the X, Y, or Z axis. Do not apply shock more than
two times per second.
c. Non-operating
The limits of non-operating shock apply to all conditions of handling and
transportation. This includes both isolated drives and integrated drives.
The drive does not cause drive damage or performance degradation
while subjected to non-repetitive shock not exceeding:
50 Gs at a maximum duration of 11 msec (half-sinewave)
Shock may be applied in the X, Y, or Z axis.
d. Packaged
The drive as packaged by Seagate for general freight shipment with-
stands a drop test against a concrete floor or equivalent with specifica-
tions not exceeding:
20 pounds (8.95 kg) for pack’s gross weight
48 inches (1,070 mm) for distance dropped
Drop test applies to a single or multiple drive pack.
