SCS I Devices
No two SCSI devices connected to the same SCSI controller can have the same SCSI ID. If
another SCSI device is connected to the same controller, check its SCSI ID in the Compaq
System Configuration Utility before beginning installation procedures for an additional drive
(see Chapter 3). The SCSI ID is set by jumpers ID 2, ID 1, and ID 0 located on each SCSI
device.
The following chart provides the SCSI ID jumper settings for Compaq SCSI hard drives.
