Expansion Modules
Expansion modules enable the library to expand by adding space for tape drives, I/E stations, and
cartridges. Each expansion module can add several hundred LTO cartridge slots, depending on the
number of tape drives installed and whether an I/E station is installed. See
Figure 3 and Figure 4 .
The library maximum configuration includes 11 expansion modules for a total of 12 modules. Expansion
modules can only be added to the right of the control module.
NOTE:
Expansion modules in positions 9-12 are storage-only modules and do not contain I/E stations or
drives.
The expansion modules can accommodate the following components:
• I/O management unit (optional)
• Tape drives (optional)
• I/E station (optional)
