The DBx Module 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 Target Diagnostics LED-to-Assembly Map. Each LED flashes the Morse Code dot/dash pattern shown in LED Morse Code patterns and descriptions 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.
