3. Remove a blank module cover. See the Figures on page 15 for slot
locations.
4. Line up the connectors and firmly seat the FIM onto the main board.
5. Secure the Dual FIM module onto the main board using the screws
and lock washers provided.
6. Replace the controller cover and secure it with its screws (see “To
install the LX/700-user controller cover:” on page 100, “To remove the
MX/100-user controller cover:” on page 100, or “Removing/Replacing
CX/CXi/MXe Controller Cover” on page 101).
Tip: See also “Add Controller FRUs” on page 116 and “Replace Controller
FRUs” on page 125.
Tip: You may not install a FIM in a CX or CXi controller.
Tip: Ensure that the type of the optical interface matches that of the mating
unit (820nm single-mode, 1300nm single-mode, or 1300mn multi-mode).
