Removing Drive Screws 12. Check the SCSI address/jumper settings on the replacement drive, using the following information sections. B-15 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 B­8. If you do not need to change the drive's address, go to Step 10 of this installation procedure. Locate the jumpers at the back of the CD-ROM drive. 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. Check that the other jumpers are set correctly. Do not use SCSI ID 7 for your CD-ROM drive's SCSI address. The host SCSI controller uses SCSI ID 7. NOTICE: 3. Use needlenose pliers to remove the SCSI terminators, if still attached to the drive. B-16 SCSI ID 0 1 2 default SCSI ID 4 5 6 3 Figure B­8.
