? Terminator Power Source Options ??????????????????????????????????????????
????????????????????????????????????????????????????????????????????????
? 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. ?
????????????????????????????????????????????????????????????????????????
ST410800WD drives are shipped without terminators and have
empty terminator sockets on the PCB. You must provide
termination resistors for these drives.
