Diagnostic Tests During Power-up and Reset
The Cavium monitor diagnostic tests can be executed during power-up or invoked from the
monitor’s command prompt. This is accomplished by changing the state of the monitor
configuration parameters that define power-up and reset diagnostics mode. If the poweron-
diags parameter is set to “on”, the monitor invokes the diagnostic tests after a reset of the
hardware. Results are displayed to the console including whether the test passed or failed.

POST Diagnostic Results
The ATCA-9305 Power-On Self-Test (POST) diagnostic results are stored as a 32-bit value in
memory accessible by the management console at location 0x80080A6C. Each bit indicates
the result of a specific test, so this field can store the results of up to 32 diagnostic tests.
