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 250 and connect the other cable

connectors to any internal SCSI drives as required. See Figure 7.

Figure 3-9. Connecting Internal and External Drives

8. Connect an active terminator to the end of the SCSI ribbon cable at the

end farthest from the controller. See Figure 7.

9. Connect a wide, round, 68-pin VHDCI cable to the external SCSI

connector on the AcceleRAID 250 and connect the other end of the

cable to an external drive cabinet as required. See Figure 7. External

drive cabinets usually have termination built into the end of the SCSI

bus.

10. Connect a wide, 68-pin, high-density SCSI ribbon cable to the SCSI

to any internal SCSI drives as required.

Note

If a narrow SCSI connector is available on the system

board, this should be used for non-disk SCSI

peripherals, such as tape or CDROM drives which

will not be a part of a RAID array.
