7.5.4Shock 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 11, and in accordance with the restrictions of Section 11.3.

7.5.4.1Shock

a.Operating—normal

The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding 70 Gs at a maximum duration of 2ms (half sinewave). Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.

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 11ms (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 once every 2 seconds.

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 11ms (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 2ms (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 200 Gs at a maximum duration of 0.5ms (half sin- ewave) does not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or Z axis.

d.Packaged

Disc drives shipped as loose load (not palletized) general freight will be packaged to withstand drops from heights as defined in the table below. For additional details refer to Seagate specifications 30190-001 (under 100 lbs/45 kg) or 30191-001 (over 100 lbs/45 Kg).
