8.3.1 52-6120A - XR Dual MADI Module, multimode

Meaning of the LEDs of the 52-6120 Module.
1. This LED is permanently on if the module is powered.
2. Indicates, that the module is running. This LED blinks. Seen from left to right over the entire system, these LEDs should
blink as a moving light.
3. LED 3 indicates, that routing kernel no. 1 is sending data to the outputs of the upper MADI port. This LED is blinking if
the first kernel starts malfunctioning. That means, the first kernel should send data to the outputs of the upper MADI
port, but it does not. If a second, redundant routing kernel is available, LED 4 indicates, that the second routing kernel
is operating now.
4. Normally, the first kernel should send data to the outputs of the upper MADI port. If the first kernel is malfunctioning,
LED 4 indicates, that routing kernel no. 2 is sending data to the outputs of the upper MADI port.
5. The LED indicates, that routing kernel no. 1 is locked to the inputs of the upper MADI port.
6. If a redundant kernel is installed, this LED indicates, that routing kernel no. 2 is locked to the inputs of the upper MADI
port.
7. LED 7 indicates, that routing kernel no. 1 is sending data to the outputs of the lower MADI port. This LED is blinking if
the first kernel starts malfunctioning. That means, the first kernel should send data to the outputs of the lower MADI
port, but it does not. If a second, redundant routing kernel is available, LED 8 indicates, that the second routing kernel
