Terminating a SCSI bus
If the integrated SCSI bus does not include external storage
subsystems or stand–alone devices, you must terminate the bus at
its rear panel connector. (Internal tape and disk drives will not
operate correctly unless the bus is properly terminated.)
IMPORTANT: In most cases, your computer is shipped with a SCSI bus
terminator (DGC part number 111–3468) already installed in the
integrated SCSI rear panel connector.
You terminate each expansion SCSI bus with a terminating plug
that you install on the unused bulkhead connector on the outside of
the last unit. Do not terminate any of the SCSI devices within an
external subsystem.
IMPORTANT: You do not need to terminate any unused SCSI
connectors on expansion I/O board(s).
To locate the SCSI bus terminators and connectors for a stand-alone
drive or storage subsystem, refer to the device–specific manual for
that drive or subsystem.
Recording your SCSI configuration
IMPORTANT: Record your system configuration in the blank SCSI Configuration
Worksheets provided at the end of this chapter.
In the example worksheets (Figures 3–5 and 3–6), we’ve recorded
the SCSI configuration for a sample AViiON 5500 system.
Figure 3–4 illustrates this sample SCSI configuration. Figure 3–5
records the sample configuration for the integrated bus; Figure 3–6
records the expansion bus configuration for the sample
configuration.
