2.2.6.3Internal and External Bus Connections

If you have both internal and external SCSI device connections to your host adapter, you must terminate the last internal and last external devices on the SCSI bus. You must also disable the termination on all other devices. Termination on the host adapter is automatically disabled in this case.

Figure 2.14 shows an example of how termination is determined for this

SCSI bus configuration.
