Installation guide

Determine SCSI termination
Follow these simple rules and use the table to determine where you
need to provide SCSI termination.
• In a SCSI chain the first and last device in the chain must be
terminated with no termination in between.
• Termination is either internal or external. External termi-
nation requires a termination block. The first device is
always
the Macintosh, which is terminated internally.
If you are not sure if your other SCSI device is internally ter-
minated, check the documentation for the particular SCSI
device.
