SCSI Cable Specifications
Use cables that conform to SCSI-3 specifications.
Cable length for differential configurations
The total length of all internal and external cables on the SCSI bus must not
exceed 25.0 meters (82 feet).
Determining the cable length for each bus
1. For each bus, add the lengths of all external SCSI cables.
2. To that total, add the SCSI cable lengths used by the library for each bus:
For each tape drive, add 28 cm (11 in.) to allow for the cable used by the tape
drive inside the library.
For each jumper you plan to install on the library to connect sequential
devices to the same bus, add 5 cm (2 in.).
Add 13 cm (5 in.) for the internal cable used by the library itself.
