External Bus Connections

If you have only external SCSI device connections to your host adapter,
you must terminate the last external device on the SCSI bus. You must
disable the terminators on all other devices. Termination on the host
adapter is automatically enabled in this case.

Figure 2.13

shows an example of how termination is determined for this

SCSI bus configuration.
