NTRODUCTION
The Adaptec SCSI Card 39160 enables you to connect up to 30
SCSI devices—such as very large arrays of high-performance
HDDs, external storage subsystems, clustered configurations,
Ultra160 hard disk drives, scanners, and CD-ROM drives—to
any Intel-based computer with 64- or 32-bit PCI expansion slots.
The Adaptec SCSI Card 39160 has two independent SCSI chan-
nels, each with a maximum throughput of 160 MBytes/sec. SCSI
Channel A (marked "CH 1/A" on the card) has two internal con-
nectors and one external connector. SCSI Channel B (marked
"CH 2/B" on the card) has one internal and one external
connector.

You can connect Ultra160 and Ultra2 SCSI devices to the 68-pin
Low Voltage Differential/Single-Ended (LVD/SE) connectors on
both SCSI channels. Or you can operate the newer Ultra160 and
Ultra2 devices at their maximum speed on Channel B while at
the same time using legacy SCSI devices on Channel A.
Although the Adaptec SCSI Card 39160 is a 64-bit PCI card, it
also 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.
