6.5.4Shock 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 10.3.
6.5.4.1Shock
a.
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding:
•1000 Gs at a maximum duration of 0.5ms (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.
Note. This specification does not cover connection issues that may result from testing at this level.
b.
The limits of
The drive subjected to nonrepetitive shock not exceeding the three values below, shall not exhibit device damage or performance degradation.
•1000 Gs at a maximum duration of 0.5ms (half sinewave) Shock may be applied in the X, Y, or Z axis.
c.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.
