After the POST completes and the system is idle, the console outputs a ‘‘rotating
bar’’ to the LED display.
Refer to Chapter 4 for more information about these tests.
2.4 Troubleshooting
The Digital Alpha VME 4 modules include extensive diagnostic (POST)
capabilities that are normally executed on power-up. These include both
SROM and flash ROM-based code.
SROM-based diagnostics are always executed on power-up and use decreasing
numeric codes (8, 7, ...1) to indicate status on the dot matrix display. All SROM-
based tests must pass successfully before the flash ROM-based diagnostics and
console diagnostics are run. If one or more SROM diagnostics fail, the flash
ROM-based diagnostics and the console diagnostics will not be loaded and a
single > prompt will be displayed on the console terminal. The code of the failing
diagnostic will be on the dot matrix display. Additional information appears on
the console terminal if present.
Once the SROM diagnostics complete successfully, the flash ROM diagnostics will
be loaded, decompressed and executed. Flash ROM diagnostics use an ascending
(A, B, ..., I) character-based code to indicate progress. If one or more flash ROM-
based diagnostics fail, the code representing the FIRST error will remain on the
dot matrix display and alternate between dim and bright intensity.
