External SCSI Devices

The SCSI Cable Terminator II provides proper termination for external SCSI devices attached to a Macintosh IIfx computer. If an external device has built-in termination, you must disable the built-in terminator and install the SCSI Cable Terminator II.

Caution: Never install more than one SCSI Cable Terminator II on a Macintosh llfx SCSI daisy chain or you could damage the equipment.

Internal Hard Drives

The internal SCSI filter provides proper termination capacitance for third-party drives and Apple internal hard drives that shipped before March 1 9, 1 990. Connect the SCSI filter between the hard drive data cable and the connector on the hard drive.

Caution: When you install an internal hard drive in a system that shipped without a drive, you must connect the SCSI filter to the drive. Connecting the filter directly to the logic board will cause SCSI failures.
