Setting SCSI IDs
There are several SCSI Hard Disk Drives that may be installed in your system. For each
of these drives, you must assign an unused SCSI ID. SCSI IDs range from 0 to 15 for
wide 16-bit SCSI.
To set the SCSI ID:
1. Assign an unused SCSI ID. See Table 6-1:
• If you are adding a SCSI hard drive to your system, consider setting the new
hard drive SCSI ID to 1. However, if you have other SCSI devices connected
externally, or have changed the SCSI ID of the currently installed hard drive,
remember that this SCSI ID must be unique.
• If you are replacing a SCSI hard drive, you can use the SCSI ID number of the
current hard drive for the replacement hard drive.
• SCSI IDs are set by jumpering pins on the disk drive
Which Pins To Jumper
First, compare your drive to the photos in Figure 6-9, Figure 6-10 ,Figure 6-11 or
Figure 6-12 to determine which drive is installed in your system. Your drive will be type
A, B, C or D. Then use Table 6-2 for the proper pins to jumper on your drive.
Using the jumpers provided, set the SCSI ID on the jumper block located on the bottom
of the hard disk drive. Do not use the 12-pin jumper block next to the power connector.
