4. For each channel, set the SCSI ID on each internal drive to a unique
address between 0 and 15, but do not use address 7, as it is reserved for
the controller. See the documentation that comes with your drives for
instructions on how to do this.
m Caution
If internal and external drives are used, be sure that no
drive addresses on a given channel are duplicated.
External SCSI cabinets usually automatically assign
drive addresses according to where in the cabinet the
drives are located.
5. Be sure termination is disabled on all disk drives connected to the
controller or connected to the system board. See the documentation that
comes with your drives for instructions on how to do this.
6. Be sure that termination power is enabled on all disk drives connected
to the controller or connected to the system board. See the
documentation that comes with your drives for instructions on how to
do this.
7. Connect a wide, 68-pin, high-density SCSI ribbon cable to the internal
SCSI connector on the AcceleRAID 150 or 250 and connect the other
cable connectors to any internal SCSI drives as required. See Figure 10.
