Detailed Installation Procedure 2-15
2.2.4.1 Internal SCSI Connections
If you make only internal SCSI device connections to the host adapter,
you must terminate the last internal 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 external connector J3 on the host adapter.
Figure 2.12 shows an example of how termination is determined for this
SCSI bus configuration.
