2-36 Compaq TL881 Minilibrary System Users Guide performs and maintains an inventory of all media residing in the system, including bar code data, if the modules are equipped with bar code readers. All necessary system control operations can be performed from the control panel of the Expansion Unit, as well as from the host through software. The SCSI interface for the library robotics is designed for high-speed communication with the host, and is available in standard SCSI-2, Fast SCSI-2 or Fast/Wide SCSI configurations. In addition to system control functions, the Expansion Unit has a 16-cartridge magazine with a random access robotic mechanism. The module robotics moves cartridges between the Pass-Thru Mechanism and any of the 16 cartridge storage locations. You can designate a magazine in one of the slave modules as a mail slot for inserting or removing one or more single cartridges, which implements the SCSI Import/Export commands. NOTE: a magazine reserved for Import/Export service may not be used for data storage. The MiniLibrary Base Module The MiniLibrary Base Module has either one or two DLT drives and a 10cartridge magazine with a random access robotic mechanism. The Data Unit The LXC0016 Data Unit has a 16-cartridge magazine, a random access robotic mechanism , and no tape drives. The module robotics, under control of the Expansion Unit, moves cartridges between the Pass-Thru Mechanism and any of the 16 cartridge storage locations. SCSI Interface Configurations The MiniLibrary system standard SCSI interfaces are SCSI-2 for systems equipped with 2000XT drives and Fast SCSI-2 for systems equipped with 4000 drives. Both of these use high-density 50-pin D-series connectors. Also available, in systems equipped with 7000 series drives, is a Fast/Wide SCSI interface using high-density 68-pin D-series connectors.

The MiniLibrary Base Module
The MiniLibrary Base Module has either one or two DLT drives and a 10-
cartridge magazine with a random access robotic mechanism.
The Data Unit
The LXC0016 Data Unit has a 16-cartridge magazine, a random access robotic
mechanism , and no tape drives. The module robotics, under control of the
Expansion Unit, moves cartridges between the Pass-Thru Mechanism and any
of the 16 cartridge storage locations.
SCSI Interface Configurations
The MiniLibrary system standard SCSI interfaces are SCSI-2 for systems
equipped with 2000XT drives and Fast SCSI-2 for systems equipped with
4000 drives. Both of these use high-density 50-pin D-series connectors. Also
available, in systems equipped with 7000 series drives, is a Fast/Wide SCSI
