SCSI Cabling Guidelines 0
Refer to these SCSI cabling guidelines when completing the SCSI
cabling:
• Each device on the SCSI bus must have a unique SCSI ID. The
default settings are: library robotics = 0, tape drive 1 = 1, tape drive
2 =2. You can change these SCSI ID settings using the
Drive ID and
Library ID options on the GUI Configuration screen.
• Termination must be provided at each end of the SCSI bus (see
Terminator Power
).
• Do not mix low voltage differential (LVD) and high voltage
differential (HVD) SCSI devices on the same bus. Ensure that the
host adapters match the devices on the bus.
• All SCSI cables must be shielded or double shielded to meet EMI
specifications.
• The maximum total SCSI bus length for an LVD SCSI bus is 40 feet
(12 meters).
• The maximum total SCSI bus length for an HVD SCSI bus is 82 feet
(25 meters).
(Interlibrary and
StackLink motor
cables omitted for
clarity)
The number of drives per bus is determined by the
data transfer performance of the host and drives.
