- │ 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. (This option only on Single-Ended drives) │
