Power-on Self Test (POST)
This section describes the POST and its various tests and also explains
how to perform diagnostic tests from the front panel and from the On-
board Remote Management interface.
The Power-on Self Test (POST) and diagnostic tests are helpful tools for
testing the autoloader’s functionality and for troubleshooting errors.
With the results from the POST and diagnostic tests, you can determine
how well the autoloader is working and locate any problems
Every time you turn on the autoloader, the POST checks all of the
autoloader’s basic components. If you experience problems with the
autoloader, the POST is a good method to determine if any major parts
are malfunctioning.
