D Manufacturing Diagnostics



This appendix contains instructions for using Manufacturing Diagnostics.

You will seldom, if ever, need to use this mode. It is used in a manufacturing environment to achieve repetitive burn-in testing. The Manufacturing Diagnostics mode runs POST in a continuous loop.

Caution -

In order to run manufacturing diagnostics, you must halt the system in an orderly manner. When the operating system or any other stand- alone program has already booted, do not use the L1-A key.

Entering Forth Toolkit

To enter Forth Toolkit do the following:

    1. Save all your work and quit all applications.
    2. As root, halt the system by entering:
    /usr/etc/halt

    You are presented with either the > or the ok prompt.

If you see the > prompt, go to the step 3. If you see the ok prompt, go to next procedure.

Figure D-1 summarizes the steps you need to take to halt the system.

    3. Enter n to enter the Forth Toolkit.

    The ok prompt shows that you are in the Forth Toolkit.

Running Manufacturing Diagnostics

To run Manufacturing Diagnostics:

    1. As root, halt the system in an orderly manner.

    To do this, see the previous procedure and Figure D-1.

    2. Set the manufacturing switch to true.

    Enter setenv mfg-switch? true to set the manufacturing switch to true.

    3. Review the Manufacturing diagnostic results.

    To view the Manufacturing Diagnostics results, attach a terminal to a serial port. To do this, see the SPARCstation IPX Installation Guide.

    4. Enter reset to reboot the system.

Figure D-2 summarizes the commands you need enter to run Manufacturing Diagnostics.

    Figure D-2 Entering Manufacturing Diagnostics

At this point, the Manufacturing Diagnostics are run. These diagnostics consist of POST run in a continuous loop.

Exiting Manufacturing Diagnostics

To leave Manufacturing Diagnostics and boot SunOS:

    1. Press the Break key to leave Manufacturing Diagnostics.

    This step assumes you have connected a terminal to the system. If you did not attach a terminal to the system, press the L1-A keys simultaneously.

    Either the > or the ok prompts appears. The > prompt is the default prompt. You will see the ok prompt if you reset the system to have the ok prompt as the default prompt. To have the ok prompt as the default, see the Introduction to Open Boot 2.0.

    If you see the > prompt, go to the next step. If you see the ok prompt, go to Step 4.

    2. Enter n to enter the Forth Toolkit.

    The ok prompt shows that you are in the Forth Toolkit.

    3. Set the mfg-switch to false.

    Enter setenv mfg-switch? false to set the manufacturing switch to false.

    4. Enter reset to reboot the system.

Figure D-3 summarizes the steps you need to take to leave Manufacturing Diagnostics and boot the SunOS Operating System.
