and the floor limits the distance that the robot can travel. If the library floor is attached to the base
module, the bottom two rows (containing 16 slots) cannot be used.
The robotics unit is located at the top of the base module. When fully retracted (or parked), the
robot is fully contained within a 2U space. For safety reasons, the robot is parked before the center
door can be opened.
Within the robot, a lift table assembly contains a motor, pulleys, and cables to move the table up
and down to a specific level in the library. The picker assembly moves front and back, and
side-to-side along the table. A barcode scanner, attached to the bottom of the picker assembly,
scans targets on rack components for alignment, as well as barcode labels on tape cartridges, if
they are present. The picker has fingers that remove and insert tape cartridges among storage
slots, tape drives, or load ports.

The base module has two windows on the front for viewing the robotic motion inside the library.
A load port door is located to the right front (see
) where a 5-cartridge magazine can
be loaded with tape cartridges for insertion into or removal from the library. The load ports are
mechanical devices that enable you to import and export tape cartridges to and from the library
through removable magazines, or act as additional library storage slots. These two functions for
a load port cannot be mixed; you must either designate an entire load port to be import/export
slots or storage slots. The base module contains a load port capable of using one 5-cartridge
magazine. An operator control panel (OCP) is located at the bottom front of the base module.
The base module contains an autoranging power supply (a redundant power supply is optional),
card cage, cable management features, and space for mounting up to four LTO-technology tape
drives on the back.
