Enterprise Modular Library E-Series user guide 21
Expansion modules
Two expansion modules are available to increase library capacity beyond that provided by the base
module. These expansions modules are:
• Tape drive expansion module.
• Card cage expansion module.
Tape drive expansion module
The tape drive expansion module (see Figure 11) is an 8U chassis containing 94 LTO slots (84
permanent and 10 configurable). The number of usable slots depends on whether it is the lowest module
vertically placed in the library. If the library floor is attached to this module, the bottom row (containing
seven slots) is blocked and cannot be used.
The tape drive expansion module has three windows on the front for viewing the robotic motion inside the
library. To the right is a 10-cartridge configurable load port that holds two 5-cartridge magazines.
On the back, the module contains one primary power supply with a slot provided for another optional
redundant power supply. Up to four HP Ultrium tape drives can be installed on the module. Cable
management features are provided for cable routing and dressing.
