Adaptec SCSI Card 39160 User’s Reference
SCSI hard disk drives running under other operating systems,
see the operating system documentation.
Using Ultra160 Hard Disk Drives
■
We recommend that you connect your LVD (Ultra160 and
Ultra2) SCSI devices to SCSI Channel B and your non-LVD
SCSI devices (if any) to SCSI Channel A. This allows the LVD
SCSI devices to run at their maximum performance levels of
160 MBytes/sec or 80 MBytes/sec. Or you can connect LVD
SCSI devices to both SCSI channels. If you combine LVD and
non-LVD SCSI devices on the same SCSI channel, the data
transfer rate of the LVD SCSI devices will drop down to non-
LVD SCSI performance levels of up to 40 MBytes/sec.
■
Internal Ultra2 and Ultra160 SCSI devices come from the fac-
tory with termination disabled and cannot be changed. Proper
termination is provided by the terminator at the end of the
internal LVD SCSI cable.
Using Scanners
If you connect a scanner to the Adaptec SCSI Card 39160, you must
install the scanner manufacturer’s proprietary software drivers. See
your scanner’s documentation for details.
