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.
