7.5.3

Effective altitude (sea level)

a. Operating

–1000 to +10,000 ft (–304.8 to +3048 m)

b. Non-operating

–1000 to +40,000 ft (–304.8 to +12,192 m)

7.5.4

Shock and vibration

Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is

installed in an enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur

internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent,

it may be necessary to modify the enclosure to minimize drive movement.

The limits of shock and vibration defined within this document are specified with the drive mounted by any of

the four methods shown in Figure 8, and in accordance with the restrictions of Section 11.3.

7.5.4.1

Shock

a. Operating—normal

The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not

exceeding 15 Gs at a maximum duration of 11 ms (half sinewave). The drive, as installed for normal opera-

tion, shall operate error free while subjected to intermittent shock not exceeding 40 Gs at a maximum dura-

tion of 2 ms (half sinewave). Shock may be applied in the X, Y, or Z axis.

b. Operating—abnormal

Equipment, as installed for normal operation, does not incur physical damage while subjected to intermit-

tent shock not exceeding 40 Gs at a maximum duration of 11 ms (half sinewave). Shock occurring at abnor-

mal levels may promote degraded operational performance during the abnormal shock period. Specified

operational performance will continue when normal operating shock levels resume. Shock may be applied

in the X, Y, or Z axis. Shock is not to be repeated more than two times per second.

c. Non-operating

The limits of non-operating shock shall apply to all conditions of handling and transportation. This includes

both isolated drives and integrated drives.

The drive subjected to nonrepetitive shock not exceeding 80 Gs at a maximum duration of 11 ms (half sine-

wave) shall not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or Z

axis.

The drive subjected to nonrepetitive shock not exceeding 300 Gs at a maximum duration of 2 ms (half sine-

wave) does not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or Z

axis.

The drive subjected to nonrepetitive shock not exceeding 150 Gs at a maximum duration of 0.5 ms (half

sinewave) does not exhibit device damage or performance degradation. Shock may be applied in the X, Y,

or Z axis.

d. Packaged

Seagate finished drive bulk packs are designed and tested to meet or exceed applicable ISTA and ASTM

standards. Volume finished drives will be shipped from Seagate factories on pallets to minimize freight

costs and ease material handling. Seagate finished drive bulk packs may be shipped individually. For less

than full shipments, instructions are printed on the bulk pack carton for minimum drive quantities and proper

drive placement
