Using the Adaptec SCSI Card 19160 and SCSI Devices
Using Ultra160 Hard Disk Drives
■
We recommend keeping your Ultra160 SCSI devices separate
from your non-Ultra160 SCSI devices. Connecting a non-
Ultra160 SCSI hard disk drive to the Ultra160 SCSI connector
on the Adaptec SCSI Card 19160 causes the Ultra160 SCSI
segment of the SCSI bus to drop down to Ultra SCSI
performance levels (40 MBytes/sec).
■
Be sure to connect your Ultra160 SCSI hard disk drives to the
LVD/SE SCSI connectors on the Adaptec SCSI Card 19160 if
you want Ultra160 performance (160 MBytes/sec)
■
Internal Ultra160 SCSI devices come from the factory with
termination disabled and cannot be changed. Proper
termination is provided by the terminator at the end of the
internal Ultra160 SCSI cable.
Using Scanners
If you connect a scanner to the Adaptec SCSI Card 19160, you must
install the scanner manufacturer’s proprietary software drivers. See
your scanner’s documentation for details.
