Adaptec 39106 manual Using Ultra160 Hard Disk Drives, Using Scanners

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.
