Control Cables
Connect each MiniLibrary Base Module or Data Unit to the Expansion Unit
using one of the cables with a DB-9 male connector at the base end and a
DB-9 female at the Expansion Unit end. A cable is required for each
MiniLibrary Base Module.
NOTE:
Any of the control cables can be connected to any of the DB-9 connectors on the
back panel of the Expansion Unit. The Expansion Unit determines the location of each
module during power-up tests.
Power Cord
The detachable AC power cord is a standard grounding AC cord that attaches
to an IEC-compatible connector on the rear panel. Connect a cord to the
connector on each module, and connect the other end to a reliably grounded
AC outlet or rack power outlet.
To maintain safety compliance, use a power cord with a suitable rating that is
approved for the country in which the product is used. In the USA, cords must
be UL listed, in Canada, CSA certified, and in Europe use a harmonized cord
marked <HAR> or a nationally certified cord. Compaq specified power cords
are available as part of the associated country kits (ordered separately.)
SCSI Interfaces
Depending on the DLT drive type, fast-wide SCSI is available as a single-
ended interface, as a combination single-ended/LVD interface, or as a HVD
differential interface. Each uses two parallel female high-density 68-pin D-
Series connectors per bus. Fast Wide SCSI cables and terminators are secured
to the connectors by jackscrews.
NOTE:
Compaq strongly recommends that you use differential controllers and
high-quality SCSI cables to ensure the highest performance of your MiniLibrary. Bus
errors caused by excessive length or poor quality cables can significantly degrade
performance and reliability.
