About the SCSI Bus

LVD SCSI
For impedance and primary conductor, use a Ultra Wide LVD SCSI cable that
conforms to SCSI-3 specifications. However, when using a model equipped
with an AIT-3 drive, use an Ultra 160/m SCSI LVD cable.
The total allowable length of SCSI cables used in one LVD SCSI bus is as
follows. (This length includes the length of all internal and external cables.)
• The length of the AIT autoloader internal cable is 0.5 m (19.7 in.).
• If there are more than three devices on an LVD SCSI bus, the total allowable
length is 12 m (39.4 ft.).
This section describes common specifications of SCSI components and SCSI
buses.
The SCSI system is composed of the following components.
• Initiator
This is a host computer system that functions as an initiator program of
commands. The system consists of the application software, the operating
system, the device driver and the SCSI adapter card.
• Bus
By connecting the SCSI cables to the SCSI adapter card, the autoloader and
other devices, a path (or a bus) is created for transferring commands.
• Targets
The AIT autoloader and the AIT drive are peripheral devices (or targets) that
receive commands from the host computer. Up to 16 devices (including the
host computer) can be connected to the Wide SCSI bus. Also, up to 8 devices
can be connected to the Narrow SCSI bus.
When you are setting up the AIT autoloader using a SCSI bus, please note the
following precautions
The AIT autoloader is an LVD SCSI device. All SCSI devices connected to the
AIT autoloader on the SCSI bus must be LVD SCSI devices.
