limits the distance that the robot can travel. If the library floor is attached to the base module, the bot tom
two rows (containing 16 slots) cannot be used.
The robotics unit is l o cated at the top of the base mod ule. 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 desired level in the library. The picker assembly moves front and back, and side-to-side along
the table. A bar code scanner, attached to the bottom of the picker assembly, scans targets on rack
components for alignment, as well as bar code 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.

port door is located to the right front (see Figure 1 on pa ge 19) where a 5-car tridge magazine can be
loaded with tape cartridges for inser tion 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 bot tom front of the base module.
The
base mod ule contains an autoranging power supply (a redundant power supply is optional), card
cag
e, cable management features, and space for mounting up to four LTO-technology tape drives on the
back.
The card cage in the base module (see Figure 4 on page 22) provides six cPCI slots for the following:
