SCSI Device Jumper Settings 
No two SCSI devices connected to the same SCSI controller can have the same SCSI ID. If 
another SCSI device is connected to the controller, check its SCSI ID before beginning the 
installation procedure for the additional device. Jumpers located on each device set the 
SCSI ID. For more information, refer to the SCSI device option documentation. 
IDE Device Jumper Settings 
When installing any IDE devices (ATA hard drives, ATAPI CD-ROM drives, or ATAPI tape 
drives), be sure that the jumper on the device is set to Cable Select (CS). This setting allows 
the cable to automatically assign the device ID of an IDE drive attached to the cable. For 
information on installing and cabling IDE devices, refer to the setup and installation guide.
