Installing Your Controller
The following figure shows various SCSI cabling examples.
Terminate your SCSI devices as shown in the examples, ensuring
that the devices at the ends of the cables are terminated and the
devices in the middle are not terminated. If only one cable is
attached, then one end is the controller, and must have its
termination enabled, as indicated in the diagrams where the circled
T is in the controller.
Note: SCSI only—
Each channel being used on a multi-channel
RAID adapter must be terminated properly for its configuration
.
