are supported on all SCSI buses
Terminating SCSI Devices
You must attach a regulated SCSI terminator to the SCSI port at the end of the
SCSI bus. A terminator holds the bus at a predetermined signal level when the
bus is not active and maintains impedance matching.
All SCSI daisy chains must be terminated at the last unit attached to the SCSI
bus. Also, a terminator is built in to all SBus SCSI cards and to all host systems
to terminate that end of the bus. The regulated terminators must be used for all
50-pin SCSI buses having fast SCSI drives on a fast SCSI host.
