System Testing Information
Note: Tests are run only on the installed options in your IBM 5531 Industrial Computer.
Before a test runs, the test number is displayed on the screen along with instructions. Follow the
instructions as they appear. If you receive an error message during any of the tests, record the
error message and have the system unit serviced, unless otherwise stated.
The minimum configuration required to perform customer diagnostics is:
• System unit with 128Kb memory
• One diskette drive
• Display adapter
• Display
Some of the tests ask you IS THIS SCREEN CORRECT? Turn to the reference screen under
the corresponding test number in this manual to compare the screens.
If the screen is correct, press Y and then the Enter key to continue to the next screen or test.
If the screen is incorrect, press N and then the Enter key. Record any error message that appears
and have the system unit serviced, unless otherwise stated.
