that only 32 cartridges can be loaded. As modules are added above this module, the numbering
continues, starting with the lower left slot of the left magazine, and adding 40 storage slots for each
additional module.
Each module can be configured to contain an I/O Station, or one I/O Station can be accessed by several
modules. I/O Stations consist of five slots in the front column of the right magazine of each module,
except for the lowest module. The lowest module in a library can contain a 4-slot I/O Station only. To
enable or disable I/O Stations, go to Library > Modules and Magazines > Actions > Enable or Disable
I/O Station in the Management GUI.

Power supply

The library provides a single power supply with each library. However, a secondary redundant power
supply for the base module can be added. In addition, each expansion module with drives installed
requires a power supply.

Bar code reader

The high-speed bar code reader is a part of the Base Module. The bar code reader provides inventory
feedback to the host application, Operator Panel display, and Management GUI by reading cartridge bar
code labels. The library stores the customized inventory data in memory.
Library firmware supports a 6 or 8 character volume serial number (VOLSER) on the bar code label on
the tape cartridge. It is highly recommended to use bar code labeled cartridges. See "Labeling tape
cartridges" on page 145.
