Vibration specifications
The following table shows 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.

(1) A 0.3 g rms random vibration spectrum is applied to the bottom/top axis for a
minimum of 20 minutes per axis.
(2) A 1.06 g rms random vibration spectrum is applied to each of three orthogo-
nal axes for a minimum of 20 minutes per axis.
(3) The autoloader has been unpacked, but is not operating.
(4) The autoloader is packaged in its original shipping container.
(5) Three sweeps at one octave per minute are applied to each axis at 0.75 g
(0 . peak) input.
(6) Three sweeps at one octave per minute are applied to the top/bottom axis at
0.3 g (0 . peak) input.
