Using Ultra160 Hard Disk Drives; Using Scanners - Adaptec 1821900 Reference

Using Ultra160 Hard Disk Drives

We recommend that you connect your LVD (Ultra160 and
Ultra2) SCSI devices to the two 68-pin connectors on the
LVD-SE SCSI segment and that you connect your non-LVD
SCSI devices (if any) to the two SE (single-ended) connectors
on the SE SCSI segment. This allows the LVD SCSI devices to
run at their maximum performance levels of 160 MBytes/sec
or 80 MBytes/sec. If you combine LVD and non-LVD SCSI
devices on the same SCSI segment, the data transfer rate of the
LVD SCSI devices will drop down to non-LVD SCSI perfor-
mance levels of up to 40 MBytes/sec.

Internal Ultra160 SCSI devices come from the factory with ter-
mination 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 29160, you must
install the scanner manufacturer's proprietary software drivers. See
your scanner's documentation for details.
