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.
