Library with Mixed-Media Storage Cells

Mixed-Media Library Configurations 

Firmware problems: You can not mix LTO and mixed-media arrays and 

magazines within the same library. If you add expansion modules, the new modules 

must have the same type arrays as the existing modules.

Your robotics unit must be part number 314558705 or higher to read SDLT 

cartridge labels.

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 42

 

storage cells (see note), one or two tape drives, and a 

four-cell cartridge access port (CAP).

The base unit can be ordered originally as a 24- or 42-cell unit. If you received 

the 24-cell version, only 24

 

of those storage cells can be used unless the upgrade 

conversion bill has been installed. Without a conversion bill, the first

 

24

 

cells after the 

reserved cells can be used for cartridge storage. If the reserved cells are configured for 

storage, the numbering starts with the first physical cell on the left.

An upgrade conversion bill allows the other 18

 

storage cells in the base unit to be 

used, for a total of 42. This conversion bill is for customers who want only the base 

unit and do not expect to order an expansion module.
The CAP cells can also be configured as storage cells.

■

Drive expansion modules (DEMs) and Cartridge Expansion Modules (CEMs) can be 

added to a standard rack to accommodate various storage cell and tape drive 

configurations. 

You must have a 42-cartridge capacity base unit before you can order an 

expansion module. 

See 

 for detailed diagrams and 

dimensions. 

Mixed-Media 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.
