SCSI IDs
In addition to recognizing the ends of the SCSI chain, your computer needs
to designate the order of the links. For this reason, each device on the SCSI
chain requires a unique device ID. This ID can be any number between 0 and
15 (for Ultra Wide SCSI) other than 7, which is the factory preset for the host
adapter. The ID number (address) can be set on most SCSI devices by adjusting
jumpers on pins.
Setting the SCSI jumpers
SCSI drives contain a jumper block. A jumper block is a set of pins located on
the drive. On SCSI drives, a jumper is placed over two of the pins to configure
the SCSI drive’s termination setting. Other jumpers are placed over additional
sets of pins to configure the ID setting.
To set the jumpers for a SCSI drive:
1
Start your computer. During startup, SCSI ID numbers are identified on the
screen.
2
Make note of the SCSI ID numbers in use, then turn off your computer.
3
Look at the new drive’s jumper label to find the jumpers for setting the
SCSI drive’s termination and ID. The label is either a sticker on the drive,
or it is printed directly on the drive.
4
Set the drive’s SCSI ID to a number that is not being used by another SCSI
device.
