This section provides the basic rules and considerations for setting up
the library on the SCSI bus.
6LQJOHHQGHGRUGLIIHUHQWLDO
Every SCSI device attached to the SCSI bus must be of the same type:
either
single-ended
or
differential
. On a single-ended SCSI bus, one
signal line is used to transmit a bus signal between devices. On a
differential bus, two signal lines are used.
Your library is differential; all devices must be differential. These other
devices include the tape drives installed in the library, the adapter card
installed in your host computer, and terminators.

The Scalar AIT 220 supports AIT tapes drives with wide SCSI
configurations.
)DVW6&6,
The library supports AIT tapes drives with fast SCSI, which does not
require any special cabling or configuration. However, proper cable
lengths, stub length, and termination are more important on a fast SCSI
bus than on a regular SCSI bus.

When connecting the library and other devices on the SCSI bus, follow
these guidelines for SCSI cabling:
