Step 3.
Be sure the pins are precisely aligned with the holes in the header, and the FKM
front panel is guided into the front slot cut-out. Then, slowly and carefully apply just
enough pressure to insert the FKM module socket into position, see Figure 3.4.2b. (If you
force the FKM down when the pins are not properly aligned with the holes in the header,
the pins may become bent and the FKM damaged accordingly).
Once inserted, the FKM module will be secured by the front panel port slot cut-out, and
the retaining screw.

Figure 3.4.2b: Inserting PM Modules into a RFL 3000 4K24F
NOTE: The optional FKM slots need not be filled in order for the RFL 3000
4K24F unit to be operational. When leaving FKM slots empty, always use a
face plate (RFL 3000 FKM-BLNK) to cover the slot opening in the front panel.
This will maintain proper cooling air flow, provide required safety, during
operation as required by FCC, CE, and other regulations.
Step 4.
Once FKM modules have been installed, the chassis cover should be replaced.
To do this, reverse the procedure in Section 3.4.1.
3.4.3 Removing FKM Modules from RFL 3000 4K24F Switches
Step 1. Remove chassis cover
See procedure in Section 3.4.1 above.
Caution: Be sure the power cord is unplugged.
Step 2. Remove retaining screw holding the FKM and Face Plate
On top of the FKM module, there is one retaining screw for each FKM module,
used to secure the FKM module in position (see Figure 3.4.3a). Remove the retaining
screw of the FKM to be removed.
