Turn the chassis upside down and position the front panel so the pins of P30 and P35 on the bottom of the
RF board just begin to engage the connectors on the lower edge of the front panel assembly as shown in Figure
14). Do not fully mate them yet.
Figure 14. Mounting the Front Panel Assembly- Mating P30 and P35.
Hold the front panel in place against the chassis assembly and turn the unit over to look at the two multi-
pin connectors on the top of the RF board. See if they are engaging the corresponding connectors on the front
panel assembly (see Figure 15). Adjust the position of the RF board or the front panel assembly to ensure they
are mating properly.
Figure 15. Mounting Front Panel Assembly - Mating P50 and P51.
With the pins of all four connectors started, press the front panel onto the RF board connectors. Press only
from the bottom of the front panel to avoid flexing the RF board. You can use your fingers to press on the back
side of each multi-pin connector on the top of the RF board while holding the front panel to engage them. There
may be small areas of pins showing even after they are mated. You will know they are properly mated when the
screw holes on the bottom lip of the front panel assembly line up with the screw holes in the 2D fasteners on the
bottom of the RF board.
Secure the front panel assembly at the bottom lip to the 2D fasteners at the forward edge of the RF board
with the two 4-40 3/16” (4.8 mm) black pan head screws you removed earlier. No lock washers are used on the
external case screws.
Fasten the top of the front panel assembly with three 4-40 3/16” (4.8 mm) black flat head screws (see
Figure 4).
Replace the 3/16” (4.8 mm) black pan head screw and, if used, lock washer in the 2D fastener (see Figure 3
on page 7).
