Installation
Set the HW/SW Jumper
• The jumper is located on the circuit board, labeled
“J1”.
• Use needle-nose pliers to set the jumper.
Hardware: The media converter settings can be monitored
using SNMP, but cannot be managed.
Software: The media converter settings are monitored and
managed using SNMP.
Install the Slide-In-Module
IMPORTANT: Slots in the PointSystem™ chassis that do not have a module
installed MUST have a protective plate covering the empty slot for Class A
and/or Class B compliance.
Note: The slide-in-modules may be installed in any slot and in any order.
To install the CFMFF4040-100 optical line converter:
1. Locate an empty installation slot on the PointSystem™ chassis.
2. Carefully slide the converter into the slot, aligning the it with the
installation guides.
3. Ensure that the module is firmly seated inside the chassis.
4. Push in and rotate the the attached panel fastener screw clockwise to
secure the module to the chassis front.

Install SFP Transceiver Modules
To install SFP transceiver modules into the
CFMFF4040-100 converter:
1. Position the SFP transceiver module at
the installation slot so that the label
faces to the right.
2. Carefully slide the module into one of
the installation slots, aligning the
module with the internal installation
guides.
3. Ensure that the module is firmly seated
against the internal mating connector.
4. Repeat steps 1 thru 3 to install a
module into the second slot.

Remove SFP Transceiver Modules
To remove a SFP transceiver module from
the CFMFF4040-100 converter:
1. Swing the handle on the SFP transceiver
to the “out” position, shown to the
right.
2. Carefully pull the module outward until
it separates from the converter.

Operation
Status LEDs
The CFMFF4040-100 optical line converter is designed to
operate without user intervention. Use the status LEDs to
monitor the operation of the converter in the network.
PWR (Power) On = Connection to external power.
LK1 (Fiber Link 1) On = Fiber port 1 is receiving a signal.
LK2 (Fiber Link 2) On = Fiber port 2 is receiving a signal.

Link Pass-Through
The Link Pass-Through feature allows the media converter to monitor both
fiber RX (receive) ports for loss of signal. In the event of an RX signal loss (1),
the media converter will automatically disable the TX (transmit) signal (2),
thus, “passing through” the link loss (3). The far-end device is automatically
notified of the link loss (4), which prevents the loss of valuable data
unknowingly transmitted over an invalid link.
