If internal SCSI device connections to both internal connectors (J2 and
J4) on your host adapter have been made, then terminate the internal
devices on each end of the SCSI bus. You must disable the termination
on all other devices. Termination on Channel A of your host adapter is
automatically disabled in this case. Remember, you must not use the
external connector J3 if you use both internal connectors.
Figure 2.15 shows an example of how termination is determined for this
SCSI bus configuration
