Step 3: Finding the Connector

The SCSI cable should have 1 or more unused connectors on the end
opposite the adapter, as shown, find a connector not in use. We recommend
a connector at the very end of the 50 pin SCSI cable.

Note:
If no free 50 pin SCSI connector exists, see “Troubleshooting”, page 19.

Step 4: Choosing the Configuration

SCSI ID selection

If no other SCSI devices are in the system, we recommend the default
jumper settings. In this case, go on to Step 6: “Connecting the Drive”.

If one or more SCSI ID’s are assigned, you must determine if the
default ID# 6 is free. If SCSI ID# 6 is assigned, you must change the
CD-R drive to a free ID# via jumpers at rear of drive.

Termination

If CD-R drive is on end of SCSI cable, leave terminators in place.

If CD-R drive is not on end of SCSI cable or last physical device,
carefully remove the drive termination (resistors) and assure the last
physical SCSI device is properly terminated or activated.

Note:
Only the last physical SCSI device needs to be terminated.

Step 1: Opening the Computer

Remove the computer’s cover as directed in the Owner’s Manual.

Step 2: SCSI Configuration

Locate the 50 pin SCSI cable in your computer. One end of the cable is
connected to the SCSI host adapter card as shown below.

Note:
The following types of cables may be installed in your computer:

Note:
There may already be internal or external SCSI devices (HDD, Scanner,
CD-ROM) connected to the SCSI cable. If so, you must determine the
SCSI ID# of each SCSI device. This information will be required for Step
5 “Setting the Jumpers”. Refer to SCSI device(s) for ID data. In some
cases a SCSI chip set may be implemented in the motherboard.
