    Introduction to SCSI-2 Introduction to SCSI-2 SCSI (Small Computer System Interface) is an I/O bus protocol that provides high performance, peer-to-peer data communications for up to 16 devices, including one or more host computers. The main advantage for using SCSI-2 is that all the initialization information is stored within the SCSI-2 device.

  • Page 22: Narrow And Wide Scsi Conþgurations

    Introduction Narrow and Wide SCSI Configurations SCSI controllers can be daisy-chained together in a narrow configuration using a 50-conductor, 8-bit cable to connect up to 8 SCSI devices on the bus. A wide configuration expands the bus to a 68-conductor, 16-bit bus that can handle up to 16 SCSI devices. Both narrow (8-bit) and wide (16-bit) devices can be intermixed on a wide SCSI bus (68-pin connector) only.

  • Page 26: Electro-Static Discharge Precautions

    Electro-static Discharge Precautions Motorola strongly recommends that you use an antistatic wrist Use ESD strap and a conductive foam pad when installing the MPMC101 or MPMC102. Electronic components can be extremely sensitive to electro-static discharge (ESD). After removing the board from the protective wrapper, place it component side up on a grounded, static-free surface.

You do not need to install the AIX driver if the carrier board has an NCR53C825 SCSI-2 controller, or if the MPMC101/MPMC102 is installed in the system when AIX is installed and configured. In these situations, the wide SCSI controller driver is installed automatically during Initial Program Load (IPL).
