Hardware Verification

Master Controller Verification

When the Power-On Self Test (POST) is initiated on booting the system, two columns of information appear on the screen. The left-hand column identifies the item being tested; the right-hand column indicates PASS, FAIL, or the amount of memory allocated.

If any item has FAIL in the right-hand column, report this information when making a service call. If you are using a Master Controller II+ or Master Controller III, you may be asked to check your configuration setup parameters as described in Chapter 3 of the AT&T Applications Controller User Guide (Document No. 585-249-710) or the AT&T Master Controller III User’s Guide (Document No. 560-407-150).

To fully diagnose any problems on a Master Controller II+ or Master Controller III, use the Diagnostic Program provided with your processor. Consult the AT&T Diagnostic Program User’s Guide (Document No. 560-407-151) for comprehensive instructions on how to use the program. If you have a Customer Test disk provided with your system, use it to fully diagnose any problems. To run the Customer Test diagnostics, follow these steps:

1.Insert the Customer Test disk supplied with the system into disk drive A.

2.Boot the system by turning power ON or if the system is on, do a shutdown and press the Reset button.

The system boots from the Customer Test disk and displays the Customer Test introduction screen.

3.Press Enter to continue.

The Customer Test main menu appears.

4.Select either System Checkout or Test All Modules by using the DA key.

NOTE:

If Test All Modules appears on the main menu, Customization Screen will also appear. The interactive mode must be set to on on the Customization Screen before selecting Test All Modules for the speaker test, floppy disk drive test, keystrokes and typematic tests, and mouse tests to be performed. If the interactive mode is off these tests will not be performed.

5.Press Enter .

6.Follow the directions on the screen to run the diagnostics.
