Figure 3.4.3b: Removing an FKM Module
If the slot from which the FKM module has been removed is to remain unused, be
sure to install an FKM-BLNK face plate to cover it. If another FKM module is replacing
the one that has been removed, follow the steps as described for installing a FKM
module, discussed in Section 3.4.1.
Step 4.
Once FKM modules have been removed, the chassis cover should be replaced.
To do this, reverse the procedure in Section 3.4.1.

Manual settings for Fiber ports (HDX or FDX)
The factory default settings on RFL 3000 4K24’s optional fiber ports are at full-
duplex (FDX). Each fiber port can be set as half-duplex (HDX) by manually settings the
DIP switches. These are provided under the fiber ports inside of the chassis as shown in
the figure 3.5. The blue DIP switches control half- duplex and full-duplex of fiber port #
2 and # 4.
