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.
Alarm/Status Priority Class LED
Chassis temperature over limit 1 Critical Flashing RED
Frame fan stopped 2 Critical Flashing YELLOW
12VA or 12VB missing with
PSUA or PSUB present 3 Redundancy problem RED
Frame fan low speed 4 Maintenance problem YELLOW
All good All good Green
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.
