Combined (Circle) Configuration   Default
•
One 3-connector SCSI cable connected from system board Channel B (CN29)
to the SCSI Backplane board (CN12 and CN13)
•
This configuration creates a SCSI chain with the host adapter in the
middle and terminators at each end.
•
The terminators on the backplane board are always Enabled, so in this
configuration the terminator on the system board must be set to Disabled
(in the SCSISelect Configuration Utility  see Chapter 5 for details).
•
The figure below shows the correlation between SCSI hard disk connectors
and switch ID settings. Note: Switch ID settings do not have to be
sequential. Do not assign the same ID number to more than one device. (See
section 3.8.3 for details.)
