2Support for Older SCSI DevicesIf you have single-ended Ultra SCSI and earlier SCSI devices,Adaptec recommends that you connect them together on onechannel of the Adaptec SCSI Card 39320D and that you connectnewer Ultra320/160 SCSI and Ultra2 devices to the otherchannel. This allows the Adaptec SCSI Card 39320D to dedicateone SCSI channel to support a slower transfer rate for the Ultra(legacy) devices, while the second SCSI channel can support LVDdevices in Ultra320, Ultra 160, or Ultra2 speeds. It also allows youto use longer cable lengths for the newer SCSI devices.Discharge any static electricity build-up before handling yourSCSI card by touching a grounded metal object (like the exposedmetal parts on the back of your computer).If you connect Wide Ultra/Ultra SCSI devices to thesame SCSI channel as Ultra320/160 and Ultra2 SCSI devices,the data transfer rate for the Ultra320/160 and Ultra2 SCSIdevices will drop to Ultra SCSI performance levels. To achievemaximum data transfer rates for the newer SCSI devices, besure to connect them on their own SCSI channel.NOTEI NSTALLING THE ADAPTEC SCSI CARD 39320DSTEP 1Turn OFF power to the computer and disconnect thepower cord.WARNING
