Figure 2-5 shows where to install terminating resistors if the GPIB-SCSI-A
is at a location other than the end of a system.

Connecting the Hardware
The following are general instructions for connecting the GPIB-SCSI-A
to the Sun SPARC system. Consult the chapter on installing external drives
in the installation guide that came with your Sun SPARC system for
specific instructions and warnings.
There are two methods for connecting the GPIB-SCSI-A to the Sun SPARC
system. One method is connecting the GPIB-SCSI-A directly to the Sun
SPARC system unit by using a cable with the proper connectors at each
end. The other method is daisy-chaining.
Daisy-chaining
is a means of
connecting a number of SCSI devices to a host; thereby, a single port on
the host can serve a variable number of devices. Daisy-chaining is the
suggested method for connecting the GPIB-SCSI-A to the Sun SPARC
system.
