├──────────────────────────────────┴───────────────────────────────────┐
│ 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. │
