2.1 What Is in This Chapter?
Introduction In the first stage of the troubleshooting sequence, it is important to correctly interpret the error code on
the remote controller display. The error code helps you to find the cause of the problem.
Shutdown For some errors, the system only shuts down when the error occurs several times. This means that
you have to wait until the system shuts down to be able to see the flashing LED on the front panel and
the error code on the remote controller.
