Library with LTO Storage Cells
LTO Library Configurations 
Caution – 
Firmware problems: You can not mix LTO and mixed-media arrays and 
arrays within the same library. If you add expansion modules, the new modules must 
have the same type arrays as the existing modules.
For each library:
The Base Module contains the robotics unit and the base unit:
The robotics unit has the robotic components and the keypad
The base unit has up to 50 storage cells (see note), one or two tape drives, and a 
five-cell cartridge access port (CAP).
Note – 
Only 30 of those storage cells can be used unless the cartridge upgrade 
conversion bill has been installed, allowing the other 20 storage cells to be used. With 
no upgrade, the first 30 storage cells after the reserved cells can be used for cartridge 
storage. If the reserved storage cells are configured for storage, the numbering starts 
there. The CAP cells also can be configured as storage cells.
Drive expansion modules and Cartridge Expansion Modules can be added to a 
standard rack to accommodate various storage cell and tape drive configurations. 
Note – 
You must have a 50-cartridge capacity base unit, either from the initial order or 
with the upgrade conversion bill, before you can order an expansion module.
See 
 for detailed diagrams and 
dimensions. 
LTO Library Internal Addressing
The numbering scheme uses the library, module, row and column scheme. Four 
integers are used to represent the cartridge and tape drive slots, as viewed from the 
front of the library. 
1. Library number (always 0)
2.  Library module number 1 (top of rack) through 5 (bottom of rack)
3.  Row number 1 through 9 (Base Module) or 1 through 12 (expansion module)
4.  Column number 1 through 9 for Base Module and Drive Expansion Module, 1 
through 11 for Cartridge Expansion Module See 
 for more information.
