Chapter 2 Installation
Connecting the SCSI Bus Cable
Connect the S-AIT library and the host computer with a SCSI cable. This
section describes how to do so. Use an Ultra 160/m SCSI LVD cable commonly
sold in stores to connect the unit to the SCSI bus. The S-AIT library uses a 68-
pin half pitch connector.
Caution
• The S-AIT library does not support single-ended.
• Do not connect the S-AIT library to an HVD (High Voltage Differential)
SCSI bus. If you do, the unit or other devices on the SCSI bus may be
damaged.
• Turn off all the connected devices before connecting the SCSI cable,
including the S-AIT library and the host computer.
• If the S-AIT library is the last or only device on the SCSI bus, make sure that
you connect the supplied terminator to the open connector.
• Make sure that the SCSI connectors are securely connected.
• With LVD (Low Voltage Differential) SCSI, make the total length of the
SCSI cable (internal and external) connecting the host computer and the
device at the end of the SCSI bus shorter than 12 m (39.4 ft.). The S-AIT
library internal cable length is 2 m (80 in.).
• SCSI cables cannot be branched.
A SCSI bus allows you to connect up to fifteen peripherals to the host computer,
including the unit.
Notes
• The default factory settings of the SCSI IDs are as follows.
- Library: 0
- S-AIT Drive 1: 1
- S-AIT Drive 2: 2 (with two drives installed)
• Do not use repetitive SCSI IDs on the same SCSI bus.
• For details about the SCSI ID settings, see “Setting the SCSI ID” (page 27).
