To install a new CD-ROM drive:

documentation for instructions.
2. Insert the new CD-ROM drive through the front panel.
3. Secure the CD-ROM drive to the chassis using the screws removed previously.
4. Connect the SCSI cable and power cable to the CD-ROM drive. The SCSI cable is
keyed to ensure proper insertion, so that the red stripe (pin 1) is adjacent to the power
connector.

the new CD-ROM drive to the connectors on the drive and the system board.
