the QPM card with the connector socket inside the unit.
Step 5. Be sure the QPM front panel is guided into the front slot cut-out first and then
precisely aligned the header pins with the holes in the socket slot mounted on
the board. Slowly and carefully apply enough pressure on both rear corner of
QPM Module to insert the QPM card’s pins into position. A click sound will
determine the proper lockup of the two, see Figure 3.9.2b. (If you force the
QPM down when the pins are not properly aligned with the holes in the header,
the pins will become bent and the QPM is damaged).
Step 6. Once inserted, the QPM card will be secured by the header connector, the front
panel port slot cut-out, and retaining screws. Use #4-40 Pan Head retaining
screws to secure the module rear part and #4-40 Flat Head (Black color)
retaining screws for front panel.
NOTE: If a QPM is difficult to install, try it in another port slot. Some of the
port modules may fit easily in one port slot and be very hard to install in
another.

NOTE: All QPM slots need not be filled in order for the Magnum Q-Series
unit to be operational. When leaving QPM slots empty, always use a face
plate (Magnum QPM-FP) to cover the slot opening in the front panel. This
will maintain proper cooling air flow, safety, and operation as required by
FCC, CE, and other regulations.
