SCSI ID Pins
Every device on the SCSI bus must have a unique SCSI ID. You must ensure that the SCSI ID of
the drive is not the same as the host adapter (typically 7 or 15), and to ascertain whether or not
the FFD shares the SCSI bus with additional drives.
After doing this, assign an unused ID to the FFD. For example, if the FFD is the only device on
the SCSI bus, use the factory default ID setting 0 (as it may be any ID except that of the host
adapter).
The FFD SCSI ID can be set via the header or via the 80-pin SCA-2 connector disk type or via
the auxiliary connector for the 68-pin.
To select the required ID using the header settings:
1.
Verify that the SCSI ID pins in the 68-pin auxiliary connector are not being used, or define
the ID as 0 for the 80-pin SCA-2 connector.
2.
Set the headers as described in Table 35.
