���������������������������������������������������������������������Ŀ
� 2 & 4 � Initiator supplies power over the SCSI Bus for terminators. �
� Drive supplies no terminator power. �
� 1 & 2 � Drive supplies power for its own terminator resistor-paks �
� but not to SCSI Bus. This is the factory setting. �
� 1 & 3 �
� AND � Drive supplies power for external terminator at end of the �
� 2 & 4 daisy chain. Terminator resistor-paks must be removed. �
� This option is recommended only for last drive on daisy �
� chain. �
������������������������������������������������������������������������
ST410800ND drives are shipped without terminators and have
empty terminator sockets on the PCB. You must provide
termination resistors for these drives.
