Changing FKM modules in a RFL 3000 4K24F Switch is a complex procedure that
requires great care. Please read the Port Module Insertion Guide and this 4K24 Manual
thoroughly before doing any field changes of FKM modules.
If you are installing an FKM, make sure the FKM Module package has all
necessary accessories to install it properly. The FKM Module package for field
installation comes along with an FKM Module and instructions enclosed, the Fiber Port
Module Insertion Guide.
3.4.1 Preparation for Changing FKM Fiber Port Modules
Step 1.
Remove Chassis Cover
RFL 3000 4K24F chassis has top and bottom parts that are factory assembled
using 22 Philips-head screws. There are 7 screws located on the front-top of the unit and
three screws each on the left and right edges. Remove these screws. Once these are
removed, the top cover is easily lifted off the chassis base. When the chassis top cover
has been removed, the interior of the 4K24F unit is exposed.

Caution: Be careful not to disturb the power supply.
Looking down into the RFL 3000 4K24F unit, notice that there are two FKM
connector headers located inside on the main PC board, next to Port 2C, for FKM
Module mounting. These headers are located directly behind the Fiber port cut-out.
