2.2.4.2 External SCSI Connections
If you make only external SCSI device connections to the host adapter,
you must terminate the last external device on the SCSI bus. You must
disable the termination on all other devices. Termination on the host
adapter is required in this case. Insert the plug-in HVD terminator into
the internal connector J2 on the host adapter.
Figure 2.13 shows you how to enable or disable termination for this SCSI
bus configuration.
