3 Setting up and configuring a
SCSI bus
This chapter describes how to plan and configure a Small Computer
System Interface (SCSI) bus for AViiON 5500 and 550 series
systems. In addition to instructions for connecting external
SCSI–based devices, this chapter includes the following:
D
default and recommended SCSI identification numbers
D
operating parameters for a SCSI bus and individual drives
D
operating parameters for individual drives
D
cabling restrictions
D
bus terminating rules
D
worksheets to help you prepare your SCSI configuration
IMPORTANT: If your system does not include external SCSI storage subsystems
or stand–alone SCSI devices, you probably do not need the
information in this chapter. However, you do need to terminate the
internal SCSI bus at the computer unit, as described in Chapter 2.
To ensure that your system components work together, you should
fill out the worksheets in this chapter, and make certain that your
SCSI bus adheres to the device identification and cable rules
described here. Before adding any new internal or external SCSI
devices to your system, read this chapter to plan your SCSI bus
configuration.
If your system includes external devices (drives or subsystems
housed outside the computer unit), follow the steps in the
“Connecting an external SCSI bus to the computer unit rear panel”
section of this chapter to connect those devices to your computer
unit.
