Elite 9 Installation Guide, Rev. B 19
Setting the SCSI ID jumpers
Each device on the SCSI chain must have a unique SCSI
ID. The host system’s SCSI controller usually uses the
highest-numbered ID available (ID7 in non-wide sys-
tems); therefore the lower-numbered SCSI IDs are nor-
mally used for the other SCSI devices such as this Elite
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; refer to your system or controller
user’s manual for details about its requirements
for proper SCSI device installation.
Use connector J4A to set the SCSI ID (Figure 2). Most
Elite disc drives are factory set with the SCSI ID set at 0.
To change the SCSI ID, install jumpers on the appropri-
ate pins as shown in the illustration.
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.
