The MiniLibrary System is designed for mounting in a Compaq rack,
StorageWorks metric rack, or a standard 19-inch EIA/RETMA rack. Each
module is shipped with the inner rails installed.
Every Compaq MiniLibrary System includes:
I
One Expansion Unit
I
One expandable PTM
I
One to five MiniLibrary Base Modules or Data Units, each with one or
two DLT drives
The Expansion Unit has 16 slots and no drives, and serves as controller of the
MiniLibrary System. The MiniLibrary Base Modules each have 10 slots plus
one or two drives. The Data Unit, which acts as a storage unit, contains 16
slots and no drives. The Expansion Unit, the Data Unit, and the MiniLibrary
Base Module(s) each occupy 7 in (18 cm) of rack space height.
The PTM is composed of a motor drive assembly plus sections of track whose
combined length is equal to the combined heights of the Expansion Unit plus
the MiniLibrary Base Modules. One extension section of track is needed for
the installation of each additional MiniLibrary module.
