Ventilation
Ventilation for the frame is provided by a fan mounted in the center of the rear panel. The fan
draws air through the frame and exhausts it to the rear. Ventilation slots are provided in the
chassis and cards front panels to allow air to flow into the frame.
Important Note: to ensure proper cooling, the front panel of the LUMO frame must be closed at all
times when cards are installed and operating. As well, blank card front panels must be installed if no
card is present in a slot.
Ensure that the front panel ventilation slots of the chassis and the cards are not obstructed.
Field-Serviceable Items
Field-serviceable items on the LUMO frame itself include the power supplies, the status or
controller card, and the ventilation fan.
The power supplies and status or controller card are located behind the door on the front panel.
The door must be opened to change the power supplies, and it must be removed to change the
status or controller card.
Opening and removing the front panel
The front panel of the LUMO frame is attached by swivel brackets. Two spring-loaded sliders
secure the panel in the closed position. To open the panel, pull the sliders toward the center of
the panel, and then pull the panel out until the support brackets allow it to move down below
the level of the power supplies. The supplies can then be removed.
To remove the status card, the door must be detached from the frame. Once the door is open,
push the flexible brackets apart until the door posts slip out of the holes in the brackets.
There are no electrical connections to the panel.
Reinstall the panel by slipping the door posts into the holes in the brackets, and then move the
door into position and snap it in place. The spring-loaded sliders will hold it in position.
Note that the door must be kept closed while the frame is in use, to ensure proper ventilation.
