Figure 6. Jumper Settings for an Internal Drive
SCSI Address Selection (Pins 1 through 8)
You can select the SCSI address used by the drive by placing the appropriate
jumpers on pins pairs 1-2 through 7-8, as shown in Figure 6. The SCSI address
can also be selected remotely by connecting a SCSI address-selection switch to
pins 1 through 8.
Each SCSI device on a bus must have a unique SCSI ID. The SCSI controller or
host adapter generally uses ID 7. In some systems, the boot drive uses ID 0.
Note:
In an 8-bit SCSI mode, the drive only uses SCSI addresses 0 through 7.
Parity Checking (Pins 9 and 10)
If a jumper is installed on pins 9 and 10 (the default setting), parity checking is
enabled. If no jumper is installed, parity checking is disabled, but parity is still
generated by the drive.
