Target Diagnostics
------------------

The |product| incorporates Target Diagnostics, a six-LED matrix on the rear panel that mirrors the status indicators located on each major internal assembly. The Target Diagnostic LEDs are readable with the unit rack-mounted and with the covers attached. Target Diagnostic LEDs correspond to the internal assemblies listed in :ref:`table-target-diagnostics-led-map`. Each LED flashes the Morse Code dot/dash pattern shown in :ref:`table-target-diagnostics-morse-code` to report the assembly's state (heartbeat, configuration notice, or fault).

When combined with the MagnaCTRL EPROM Editor, Target Diagnostics enables off-site personnel to interpret codes and issue corrective actions, reducing mean time to repair. Typical end-users will not reference these codes during normal operation; they are intended for Magna-Power service teams or qualified technicians.
