Installation
The FEC module inserts into a standard INFI 90 OPEN module
mounting unit (MMU) and occupies one slot. To install:
1. Verify the MMU slot assignment for the module.
2. Install a 24-pin dipshunt in all I/O expander bus sockets
(on the MMU backplane) that are between the slot assigned to
the FEC module and the slot assigned to its control module
(MFP/MFC).
3. Connect the hooded end of the cable from the termination
unit or module to the cable opening (on the MMU backplane)
belonging to the FEC slot. Do not force the cable connection to
the MMU backplane. This cable is keyed and should latch into
place when properly installed.
4. Align the module with the guide rails in the module mount-
ing unit. Slide the module into the module mounting unit until
the front panel is flush with the top and bottom of the MMU
frame.
5. Turn the two captive latches ½-turn on the module face-
plate to lock the module in place. To remove the module, turn
the captive latches ½-turn to release the module. Pull on the
module faceplate to remove it from the module mounting unit.
WARNING
Disconnect power before installing dipshunts on the module
mounting unit backplane. Failure to do so will result in contact
with cabinet areas that could cause severe or fatal shock.
