Step 2. Remove Retaining Screws on top of existing FKM or Face Plates
Looking inside the unit, there is one retaining screw on the top of each FKM
module. This screw is used to secure the FKM face plate in position. This screw is
also used to secure the FKM module, which can be subjected to significant forces
from the fiber attached cables. (See Figure 3.4.1c)

Step 3. Change out the FKM or Face Plates
FKM module removal is covered in Sect.3.4.3, installation in Section 3.4.2.
3.4.2
Installing FKM Modules in Magnum 4K24F Switches
Up to two front-mounted fiber ports may be installed in one Magnum
4K24F Switch unit via an FKM. Follow these steps to install a FKM.
Step 1.
Remove top chassis cover. See procedure in Section 3.4.1 above.
Step 2.
The figure here illustrates the basic layout of an individual FKM module. Each
FKM module fits into the selected FKM
connector header. Align the connector
socket on the bottom of the FKM module
with the connector pins on the main board
header. The pins are straight and firm to
facilitate the installation.
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
