To install a ProDAQ Function Card in any of the possible positions, use the following procedure
(See figure 3 for reference):
Remove the top cover of the module as described earlier in this chapter (Fig. 3, Pos. 1).
Remove all screws on the front-panel holding installed function cards or double filler panels in
place (Fig. 3, Pos. 2). Screws holding single filler panels don't need to be removed.
Remove the two panhead screws that mount the front panel to the modules bottom cover (Fig.
3, Pos. 6).
Please take special care of the module handles and the rings (Fig. 3, Pos. 3 and 4), which are
also fixed by those screws. The mounting angle (Fig. 3, Pos. 5) stays fixed to the front panel.
Remove the front panel by moving it forward carefully so as to avoid bending the installed
function cards.
Choose the stack and position (lower or upper) where you want to mount the function card. If
the stack, in which the function card should be installed, is covered by a double filler panel, you
have to remove it before installing the function card.
Remove the three 2.5mm panhead screws and the crinkle washers from the stack's standoffs
(Fig. 3, Pos. 9 and 10 for example).
If you want to install a function card in the upper position of a stack without having a function
card in the lower position, you need to mount both spacers (Fig. 3, Pos. 11) on each standoff. If
the stack is already populated with a function card in the lower position, mount only the bigger
spacer (Fig. 3, Pos. 8) onto each standoff.
Place a bayonet (supplied) on each standoff. Align the function card over these and slide
carefully down. The function card should be held parallel to the modules bottom cover all the
time during its way down.
Fix the function card by mounting the three 2.5mm panhead screws and the crinkle washers
onto each standoff. If you install a function card in the lower position of a stack, you need first
to mount both spacers (Fig. 3, Pos. 11) onto each standoff.
Re-mount the modules front-panel. If there is only one function card mounted in a stack, cover
the remaining opening in the front panel by a single filler panel.
Re-mount the modules top cover.
