You can connect a total of 30 SCSI devices to the Adaptec SCSI
Card 39160,with up to 15 devices on each SCSI channel. Before
connecting devices, be sure to review Setting Up SCSI Devices on
page 4.
Connecting Internal Ultra160 and Ultra2 Devices
A special 68-pin internal LVD cable is needed to connect internal
Ultra160 or Ultra2 SCSI devices. If your cables are not marked,
you can identify most LVD cables as having twisted pairs of the
flat ribbon cable between the device connectors. Some cables are
laminated so that they lay flat. Internal LVD cables usually have a
terminator built into the end of the cable.
The Adaptec SCSI Card 39160 has two separate Ultra160 SCSI
channels, as shown in the figure on page 1. Each channel has an
internal LVD/SE connector to which you can connect internal
SCSI devices. Follow these steps to connect your internal
Ultra160 and Ultra2 devices:

Ultra2 SCSI devices on a separate SCSI channel from your
Ultra SCSI devices. This allows the newer Ultra160 and
Ultra2 SCSI devices to transfer data at their maximum speed.
Locate a 68-pin internal LVD SCSI cable, which may have either

twisted wires or flat wires, as shown here.
