2.2.5.2 External SCSI Terminations
If you are making external SCSI device connections on your host
adapter, you must terminate the last external device on the SCSI bus.
Termination on all other devices must be disabled. Termination on your
host adapter is automatically enabled in this case if there are no internal
devices connected through J4.
Figure 2.13 shows an example of how termination is determined for this
SCSI bus configuration on your host adapter.
