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. The hostÕs operating system can obtain all the pertinent information about the device without referencing external setup files or software drivers.

Introduction to SCSI-2 Multiple-Device Configuration The SCSI-2 architecture allows for multiple devices on the bus where more than one host computer can communicate with more than one target at a time.

1 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.
Introduction to SCSI-2 a terminator. Where possible, the SCSI devices serving as initiators should supply terminator voltage. This is implemented with a hardware jumper on the MPMC101/MPMC102.
2Installation 2 Introduction This chapter contains instructions for installing the MPMC101 and MPMC102 SCSI-2 adapters onto a carrier board. Installation and Configuration Tasks Perform the following tasks to install and configure the MPMC101/MPMC102: ❏ Install the MPMC101/MPMC102 on the carrier board per the instructions in Installing the Adapter on the Carrier Board on page 2-2. ❏ Connect the SCSI cables per the instructions in Connecting to the SCSI Bus on page 2-6.
Installation 2 Electro-static Discharge Precautions Use ESD Wrist Strap Motorola strongly recommends that you use an antistatic wrist 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. Do not slide the board over any surface.
Installing the Adapter on the Carrier Board 5. Set the jumpers on the PMC adapter as described in Table 2-1. Table 2-1. MPMC101/MPMC102 Adapter Jumper Settings Jumper Setting JA1 When jumper is installed, the adapter supplies terminator power to the SCSI bus. Default = jumper installed JA2 The SCSI bus terminators are enabled by this jumper, as follows: Default = MPMC101 jumper installed; MPMC102 jumper not installed JA3 No user capabilities.
Installation 7. Remove the screws from the stand-offs on the component side of the MPMC101/MPMC102. 2 8. Turn the MPMC101/MPMC102 component-side down, and position it above the carrier board as shown in Figure 2-1 (an MVME160x carrier board is shown). ! Avoid touching areas of integrated circuitry; static discharge can damage these circuits. Caution Note Refer to Figure 2-1 when performing steps 9, 10, and 11. 9.

Installation 2 Connecting to the SCSI Bus You are now ready to connect the MPMC101/MPMC102 to the SCSI bus. Table 2-2.
Starting the MPMC101/MPMC102 SCSI devices on the same bus can cause permanent damage to both the peripherals and the MPMC101/MPMC102 adapter. ! 2 Cables of different impedance should not be mixed on the same physical bus. Caution 1. Attach the appropriate SCSI bus connector to the MPMC101/ MPMC102 adapter front panel connector, which is shown in Figure 2-2 below. 2. Secure the bus connector to the front panel connector with lug screws. Do not over tighten. 11668 9612 Figure 2-2.
Installation 2 Installing the AIX Driver The NCR53C825 SCSI-2 controller requires a wide SCSI controller AIX driver. If the carrier board does not have an NCR53C825 SCSI2 controller on board, install and configure the AIX driver per the instructions in Chapter 3. 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.
3AIX Driver Installation 3 Overview This chapter describes installation of the AIX SCSI-2 device driver. Before installing the AIX device driver, install the MPMC101/ MPMC102 on the carrier board per the instructions in Chapter 2, and install the carrier board into the system chassis. Installing the AIX Driver Follow these steps to install the SCSI-2 device driver using the AIX System Management Integration Tool (SMIT): 1. Log into host system as root. 2.
AIX Driver Installation 7. Answer the following questions as shown: SOFTWARE to install [devices.pci.00100300] AUTOMATICALLY install requisite software?: [yes] 3 Leave the default values in the other fields. 8. Press Enter. SMIT returns an ok command status message when the process is complete. 9. After the driver installation is complete, return to the Devices menu. 10. From the Devices menu, select Install/Configure Devices Added After IPL. A fill-in form appears, prompting you for the input device.
4Troubleshooting 4 Overview This chapter provides possible solutions for common problems encountered while installing and operating the MPMC101/MPMC102 SCSI-2 adapters. The following sections describe various symptoms and corrective actions for your computer and for the cards. If you are unable to resolve the problem after performing the tasks listed in this chapter, contact Motorola. Start-up Table 4-1. Start-up Troubleshooting Problem Possible Solution Computer will not start 1.
Troubleshooting Boot-up Table 4-2. Boot-up Troubleshooting 4 4-2 Problem Possible Solution Computer does not boot up 1. Check to see if the system is plugged in. 2. Check to see if your monitor is plugged into your video adapter. 3. Make sure the adapter is seated properly on the carrier board. 4. Remove the adapter and see if the system boots up and returns to a normal state of operation. 5. Try a known, good adapter card in your system.
PMC Adapter PMC Adapter Table 4-3. PMC Adapter Troubleshooting Problem Possible Solution Host adapter not found The PCI system in your computer is suppose to automatically configure the bus address locations. An address conflict is probably not the problem. If the driver is correctly installed, a driver message should appear on the screen during boot-up of your computer. 1. Make sure the adapter is seated properly on the carrier board. 2. Check for correct configurations of the SCSI bus cable.
