APPENDIX A—SPECIFICATIONS
ACOUSTIC NOISE LIMITS
The overall, averaged A-weighted sound pressure level (in decibels) for the
autoloader does not exceed the upper limits specified in Tabl e A -5 .
SHOCK AND VIBRATION LIMITS
The autoloader will operate normally after experiencing shock loads as
specified in Tab le A-6. The operating shock levels indicate how much shock
the autoloader can withstand while the enclosed tape drive is reading and
writing data. The non-operating and storage shock levels indicate how much
shock the autoloader can withstand when it is not operating. After
experiencing this amount of shock, the autoloader will operate normally.
