Operation
Card-Front Status LED
The Status card monitor LED is located on the front card-edge of the LUMO Status card, and is
visible through the LUMO frame front panel. This multi-color LED indicates the health status of
the LUMO frame by color, and by flashing/steady illumination.
The table shows how the various error conditions are flagged on the LUMO status card LED.
The front LED can display only one alarm/status, so it displays only the highest priority. For
example if the fan is at low speed, it should display Yellow. But if at the same time the chassis
temperature is too high, then the LED will display Flashing RED instead.
Be aware that a high priority alarm can mask a lower priority one.
