connecting external scsi devices

1The Adaptec SCSI Card 39320D enables you to connect up to 30SCSI devices—such as very large arrays of high-performancehard disk drives, external storage subsystems, Ultra320/160 harddisk drives, scanners, and CD-ROM drives—to any Intel-basedcomputer with 64- or 32-bit PCI/PCI-X expansion slots.The Adaptec SCSI Card 39320D has two independent SCSIchannels, each with a maximum throughput of 320 MB/sec. SCSIChannel A (marked CH A on the card) has one internal68-pin Low Voltage Differential/Single-Ended (LVD/SE)connector and one external very high-density cable interconnect(VHDCI) connector. SCSI Channel B (marked CH B on the card)has one external VHDCI connector.You can connect Ultra320/160 and Ultra2 SCSI devices to the68-pin LVD connectors on both SCSI channels. When connectingthese newer devices along with older legacy SCSI devices,Adaptec recommends that you dedicate them as separatechannels. See Support for Older SCSI Devices on page 2 for moreinformation.Although the Adaptec SCSI Card 39320D is a 64-bit PCI card, italso works in a 32-bit PCI slot. When installed in a 32-bit PCI slot,the card automatically runs in the slower 32-bit mode.This installation guide explains how to:• Install the Adaptec SCSI Card 39320D• Set up SCSI devices• Connect SCSI devicesI NTRODUCTION68-pin externalLVD/VHDCI connectorChannel B68-pin externalLVD/VHDCI connectorChannel A68-pin internal LVD/SEconnector Channel A
