12.4.1 Shock and Vibration
The autoloader meets the shock and vibration criteria described in the following sections.
Shock Specifications
The autoloader will operate normally after experiencing shock loads as specified in the table beneath.
The operating shoc k 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.

Shock limits
1) The autoloader is unpacked and is picking and placing cartridges from the cartridge slots and tape drive.
2) The autoloader has not been unpacked.
3) The autoloader has been unpacked, but no power has been applied.
4) A minimum of 250 shock pulses were applied to the bottom/left side/front. The shock pulses were half-sine
waves and were applied at a rate not exceeding one shock per second.
5) One 91 g shock pulse is applied to the bottom. 68 g for less than 3 ms were applied to the remaining sides of
the autoloader.
Vibration Specifications
The table below lists the vibration specifications for the autoloader during operation, non-operation,
storage, and transportation. The operating specifications indicate the amount of vibration the
autoloader can withstand while the enclosed tape drive is reading and writing data.
