in an empty position, first remove the blank card front by unscrewing it and pulling the han-
dle straight out of the slot.
2 Slide the new card into the slot and push gently on the handle to seat the connectors.
Secure the card in place with the provided front panel captive screw.
Slip the lexan that was shipped with the card over the connectors ( four BNC or eight DIN) on the
rear panel that are associated with the slot into which the card was installed. The lexan identifies
the function of the connectors for that card.
Note: Detailed information about the rear panel connections is included in the chapters describing
each card type.
Installing the Power Cord Retaining Clips
Each power supply is provided with a power cord retaining clip that holds the power cord in
place to prevent inadvertent disconnections.
With the power cord removed, install the clip into the plate that extends out beneath the power
cord socket on the rear of the frame, by slipping the two ends of the clip into a pair of holes in
the plate, and rotating the clip down into a horizontal position. Several pairs of holes are
provided to accommodate different sizes of plugs. Use the holes that position the clip closest to
the body of the plug.
Once the clip is in place, insert the power cord into the socket, and press the cord into the grip-
ping loop of the clip.
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.
