Set SCSI IDs as shown in the above figure. Set the terminating resistor (Enabled/Disabled) for the last-connected device in the SCSI chain. Set "Disabled" for all the middle devices. A terminating connector may be installed depending on the internal SCSI cable. If the SCSI cable ends with a terminating resistor, set "Disabled" for all the terminating resistors of connected devices. For the settings, see the manual provided with each device.

A file device needs settings such as a SCSI transfer rate. For the transfer rate, see the manual provided with the file device. Use the BIOS utility of the SCSI controller to make the settings. For details, see the manual provided with the SCSI controller.

An onboard Ultra320 SCSI connector can be used to connect with internal SCSI file device.
