5. How To Connect Cables To The DVD-ROM Drive
1. Connect the power supply cable, control cable and SCSI cable to the connectors at the rear of the DVD-ROM Drive.
Connect to the drive the power supply cable and control cable which extend from the side of the DVD-ROM drive
installation slot.
With the MC-2100U and the MC-8100U models be sure to connect a control cable with the same component No., as
the drive bay No., otherwise proper operation may not be possible.
Insert all connectors firmly.

(Terminate here)
SCSI cables should be connected as a daisy chain connection. Each connector may be connected to the drive
positions as illustrated in the diagram.
Terminate the physical end of the SCSI bus. To use the built-in drive terminator, read 6 -1.
It is recommended to use an external terminator to improve the stability of the SCSI bus communications.

When not using the built-in terminator, attach an active SCSI terminator to the OUT side of the SCSI connector.
In this case, set the TERM of all built-in drives to OFF.
