NOTE
When a MIX 56 system used as a multiplexer is operating normally, the High Speed and Low Speed LEDs on the LED panel and the active M13 card LED are all green. If the system is redundant, the standby card LED is orange. Any LED configuration other than this indicates the system is not operating normally.
