Connecting SCSI Cables and Devices
SCSI devices are connected by cables in one continuous line called
the SCSI chain. A SCSI chain consists of an accelerator card and the
SCSI cables and devices connected to it. The SCSI chain can
include both internal and external devices.
The PowerDomain 2940UW has one internal and one external
16-bit (68-pin) Wide connector and one internal 8-bit (50-pin) Fast
connector. You can connect up to 15 SCSI devices (seven of which
can be 8-bit Narrow devices) to a maximum of two connectors in
various configurations.
Caution: Do not connect SCSI devices to all three
connectors of a PowerDomain 2940UW.
