The autoloader will operate normally after experiencing shock loads as
specified in Table 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.
