SCSI IDs are normally used for other SCSI devices such as this Cheetah disc drive.

Note. Most SCSI controllers (host adapters) allow you to skip a SCSI ID. For example, you can have ID0, ID1, and ID3 (skipping ID2). Other controllers do not allow this so be sure to refer to your system or controller user’s manual for details about its requirements for proper SCSI device installation.

Note. This drive is SCAM (SCSI Configured Auto Magically) compliant. If the system into which you are installing this drive requires SCAM compliant drives, you do not need to be concerned about the drive ID jumper settings, as the system automatically assigns your new drive the ID it wants it to have. The system may or may not use the existing drive ID jumper settings. Setting the drive ID doesn’t hurt anything, but is not necessary in a SCAM compliant system.

Most Cheetah disc drives are factory set with the SCSI ID set at

0.To change the SCSI ID, refer to the appropriate drive section for your model.

If, after completing the installation process, the drive’s LED does not show on/off activity when the host is trying to communicate with the drive, a duplicate SCSI ID may be the problem. If this is the case, change the ID so that each device on the SCSI chain has its own unique ID. Also check your system or controller user’s manual to ensure that you have not violated its SCSI ID numbering recommendations.
