SCSI Bus Termination 2-21

Figure 2.15 External SCSI Device Termination

2.3.3 Internal and External SCSI Connections

If you have internal and external SCSI device connections to the host

adapter, you must terminate the last internal and external devices on the

SCSI bus. You must disable the termination on all other devices.

Termination on the host adapter is automatically disabled in this case.

Figure 2.16 shows an example of how termination is determined for this

SCSI bus configuration.
