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 MiniLibrary system features library robotics that can load any of the
cartridges stored in any magazine in the system into any of the tape drives,
moving cartridges among as many as six modules within the MiniLibrary
system.
Bar Code Reader
The bar code reader is 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.
Advanced Design Features
The MiniLibrary system incorporates many significant improvements in tape
drive and library design. One of the most important is the use of highly
reliable DLT technology, with media rated by the media manufacturer at better
than one million head passes.
Embedded Diagnostics
The MiniLibrary system and each of its modules provide three levels of
embedded diagnostics. The Power-On Self Test (POST) performs various
verification tests on the system’s configuration and host interface and device
control functions, as well as memory tests, at power-up. The second level of
diagnostics is the user diagnostics, which is provided for displaying and
changing configuration options. The third level, Customer Engineer (CE)
diagnostics, include advanced diagnostics to be used by CEs for servicing the
MiniLibrary system. Both the User diagnostics and the CE diagnostics can be
selected from the front panel.
User diagnostics are described in greater detail in Chapter 3, “Installation.”
