3-22 Compaq StorageWorks TL881/TL891 Family MiniLibrary System Reference Guide 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 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 singleended interface, as a combination single-ended/LVD interface, or as a HVD differential interface. Each uses two parallel female high-density 68-pin DSeries 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.
