devices that are set to terminate the bus.
Terminator Power - The SCSI terminators require adequate voltage to
properly terminate the SCSI bus. All SCSI host adapters on the bus should
be set to supply terminator power; and where possible, be located at the
end of the bus and serve as bus terminators.The terminator resistors must
be present on the first and last device on the bus only.
