HP Compaq StorageWorks TL881 DLT Mini-Library - Manual (Page 69)

Operation 2-43
Integral Fan Cooling
A single forced-air fan is mounted inside each module to provide optimum
cooling for critical parts, and to prevent the drive and robotics electronics,
motors and power supply from overheating.
Library Robotics
The DLT MiniLibrary system features library robotics that can load any of the
cartridges stored in any magazine in the system into any of the DLT tape
drives, moving cartridges among as many as nine modules within the DLT
MiniLibrary system. The robotics design utilizes the Compaq Library
Robotics, which is known for ruggedness and reliability.
Bar Code Reader
The optional bar code reader may be mounted on the cartridge shuttle in each
module. It reads bar code labels attached to each cartridge, and maintains the
bar code data in memory as part of the library System Map. Upgrade kits to
add the bar code reader are available for the MiniLibrary Expansion Unit, the
MiniLibrary Base Module and the Data Unit.
