Check the SCSI address/jumper settings on the replacement drive, using the following information sections.
B-13
CD-ROM Drive
The CD-ROM drive ships with the drive set to SCSI ID address 2. We recommend keeping the address setting at 2 unless it is used by another device. CAUTION: CD-ROM drives are susceptible to mechanical and electrostatic shock. When handling the drive, always wear the static-grounding wrist strap that came in the CD-ROM drive kit. If you need to change the CD-ROM drive's address, follow these instructions, referring to Figure A6. If you do not need to change the drive's address, go to Step 10 of this installation procedure. To change the address, use needlenose pliers to set the drive's SCSI ID to an address that is not used by another SCSI device. The host SCSI controller uses SCSI ID 7.
NOTICE:
3.
Use needlenose pliers to remove the SCSI terminators, if still attached to the drive.

DDS Tape Drive
The DDS tape drive ships with the drive set to SCSI ID address 3 and the Operation Mode switches set for correct drive operation. We recommend keeping the address setting at 3 unless it is used by another device. CAUTION: SCSI tape drives are susceptible to mechanical and electrostatic shock. When handling the drive, always wear the static-grounding wrist strap that came in the DDS tape drive kit. If you need to change the DDS tape drive's address or operation mode, follow these instructions, referring to Figure A7 for the DDS-DC drive, Figure A8 for the DDS-2 drive, and Figure A9 for operation mode. If you do not need to change the drive's address or operation mode, go to Step 10 of this installation procedure. To change the jumper settings, use needlenose pliers to set the drive's SCSI ID to an address that is not used by another SCSI device. 4.
Use needlenose pliers to remove the SCSI terminators, if still attached to the drive. If you need to change the Operation Mode switches, locate the switches on the underside of the DDS tape drive. Switches 1 and 2 are used to configure the data compression operation mode. Switches 3 through 8 are used to specify drive connectivity and functionality according to host or customer requirements. Figure A9 shows the available options.
