Adaptec 29160 Installation Guide - Page 4

Installation Guide NOTE The Adaptec SCSI Card 39160 is designed for computer system original equipment manufacturers (OEMs). Use this product with the original computer system designed by the OEM; each OEM tailors their product specifications for their specific design needs. Adaptec assumes no responsibility for incompatibility or consequential damages if you use the Adaptec SCSI Card 39160 in another computer system. All product support and services are provided by the OEM. Support for Older SCSI Devices We recommend that if you have single-ended Ultra SCSI and earlier SCSI devices you connect them to Channel A of the Adaptec SCSI Card 39160 and that you connect newer Ultra2 and Ultra160 SCSI devices to Channel B. This allows the Adaptec SCSI Card 39160 to support newer Ultra160 and Ultra2 SCSI devices at speeds up to 160 MBytes/sec while at the same time supporting Ultra (legacy) devices at speeds up to 40 MBytes/sec. It also allows you to use longer cable lengths for the newer SCSI devices. (For more information about the maximum cable lengths see the Adaptec SCSI Card 39160 User's Reference.) NOTE If you connect Wide Ultra/Ultra SCSI devices to the same SCSI channel as Ultra160 and Ultra2 SCSI devices, the data transfer rate for the Ultra160 and Ultra2 SCSI devices will drop to Ultra SCSI performance levels. To achieve maximum data transfer rates for the newer SCSI devices, be sure to connect them on their own SCSI channel. 2
