1.16 Tests and Diagnostics
The EMS may command tests to be performed on system equipment to support the operator diagnostic
processes. The results of these tests are reported to the system console and update the status display of the
equipment (if currently active). Only System Administrators or System Managers may perform tests and
diagnostics.
Test results that indicate hardware faults prompt for a work order to be generated to correct the problem.
This equipment can then be tested interactively by the operator on inactive equipment and, to a limited
degree, during active use.
