Planning for Installation and Operation
5.7.5 Vibration and Shock Tolerances
Table 5.21 lists the vibration and shock tolerance data for the 9900 subsystem. The 9900 can
be subjected to vibration and shock up to these limits and still perform normally. The user
should consider these requirements if installing the 9900 near large generators located on
the floor above or below the 9900 subsystem. Generators or any other source of vibration, if
not insulated or shock-mounted, can cause excessive vibration that may affect the
subsystem.
