Detailed Installation Procedure 2-21

2.2.6.3 Internal 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.
