____ 1. | PnP SCSI subsystems use PnP compliant host adapters and peripheral subsystems. |
____ 2. | All PnP devices implement SCSI Bus parity. |
____ 3. | PnP SCSI subsystems use single-ended electrical interface. |
____ 4. | External cable assemblies meet SPI electrical characteristics. |
____ 5. | All terminators used in the system configuration are regulated and meet SPI requirements. |
____ 6. | The host and all Peripheral Subsystems supply terminator power to the SCSI bus with a self resetting current limit device - not fuses. |
____ 7. | If there is an internal SCSI bus, it must be terminated correctly:
7.1 An internal terminator is located at one end of the internal SCSI bus.
7.2 A second internal terminator / exit point terminator is located at the other end of the internal SCSI bus
7.3 Effective 7-1-94, systems which support mixed SCSI configurations (both internal and external buses) must automatically disable the exit-point terminator when an external cable is attached. |
