Base Module

The Base Module controls the operation of the library. There must be one Base Module per library.

  • A standalone Base Module is the smallest possible configuration.
  • For best performance, place the Base Module at the center of the library.
  • Comes standard with a rotational CAP, operator panel, one drive array (8 drive bays), two LTO drives, one PDU, two DC drive power supplies, and two DC rail power supplies.
  • The Base Module contains the card cage. It ships standard with one library controller, a root switch, three library storage cards, a video card, two DC converters, two fan assemblies, safety controller, and network patch panel.
  • Optional second and third drive array (for 24 drive bays max).
  • Optional web camera.
  • Optional feature card.
  • 205 to 431 tape capacity depending on the number of drive arrays.
