Oscilloscope Module Replacement Procedure

1.If you have not already done so, pull the installed boards half way out of the card slots (refer to steps 1 through 3 of the preceding procedure "Oscilloscope Module Removal").

2.Determine which modules you want to install in the mainframe, and the slots where you want them installed.

3.Starting with the bottom slot, slide each module to be installed approximately halfway into the main- frame card slot.

4.Firmly seat the bottom card into the backplane connector. Keep applying pressure to the center of the card endplate while tightening the thumb screws finger tight.

5.Repeat step 4 for all cards and filler panels in a bottom-to-top order. See figure 6-12.

Figure 6-12. Endplate Overlap - Bottom Sequence

6.Any filler panels that are not used should be kept for future use. Filler panels must be installed in all unused card slots for correct air circulation.
