Boot Loop

Summary

In the event an exception occurs during initialization the equipment will boot loop.  Boot loop is when the machine attempts to complete it's startup procedure but can't.  Generally this can occur if there is an error with a previous test file.

After completing the procedure below please verify that your equipment is using the latest firmware available.  The latest firmware can be found here (select Elite Series Firmware tab).

Please feel free to email the TESTS folder from step 7 below to [e-mail] if you would like Humboldt to give you details about why the equipment failed to boot.  You will also need to export the log file and indicate the equipment model that failed to boot.

If the problem persists please email [e-mail].  Indicate the equipment you are using and that this article did not resolve the issue.  We will likely need you to send the log file and TESTS folder contents (see previous paragraph).
