Acoustic Noise Limits
1
The overall, averaged A-weighted sound pressure level (in decibels) for
the autoloader does not exceed the upper limits specified in the following
table.
Shock and Vibration
1
The autoloader meets the shock and vibration criteria described in the
following sections.
Shock
Specifications
1
The autoloader will operate normally after experiencing shock loads as
specified in the following table. 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.
Operating mode LpA (1)
The autoloader is powered on and idle. 55 dBA
The autoloader is operational (the carousel or
cartridge loader is moving); the tape drive is in
streaming mode.
55 dBA (2)
(1)
LpA is the average A-weighted sound pressure level over the following
frequency range: 5 Hz to 12.5 KHz.
(1)
Represents a maximum sustained operational level.
