Mechanical Vibration Specifications; Shock Specifications - HP StorageWorks XP12000 Site Prep Manual

Mechanical vibration specifications
Continuous vibration can cause a slow degradation of mechanical parts and, when
severe, can cause data errors in disk drives. Mechanical connections such as printed
circuit assembly (PCA) conductors, cable connectors, and processor backplane wiring
can also be affected by vibrations. Vibration specifications apply to all three axes.
For specification tests, see ASTM D999-91 Standard Methods for Vibration Testing
of Shipping Containers.
