SCSI cable configurations

The 4560SLX Tape Library supports multiple SCSI cable configurations on single and dual host systems.

SCSI interface connectors

The library should be attached to a low voltage differential SCSI bus. Each tape drive in the library and its robotics is a separate SCSI device. When two or more devices are connected to the same SCSI bus, each SCSI device must be assigned a unique SCSI ID. For information on assigning SCSI IDs, see “Setting a SCSI ID” on page 21.

To connect a library to a host system, the host system must have at least one wide LVD controller and the appropriate device driver software.

Interface cable specifications

The library is a high-performance system. To avoid degradation of performance, use the highest quality interface cables from a reputable manufacturer of computer cables. All SCSI cables used with the library should meet the following cable specifications:

vShielded or double-shielded as required to meet EMI specifications

vImpedance match with cable terminators that meet current SCSI specifications

vCharacteristic impedance 115 ohms

All SCSI cables used with the library should meet the following usage guidelines:

vEach end of a twisted pair ground connected to chassis ground

vMaximum cable length of 39 ft. (12 m) for an LVD SCSI bus

vCables of different impedances should not be used together

Additional specifications to ensure the highest SCSI performance can be found in the current version of ANSI X3.131.
