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.

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. SFP transceiver

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.

Operation -- continued
SNMP
Use SNMP at an attached terminal or at a remote location to supervise the
media converter by monitoring:
• Media converter power*
• Presence of SFP modules
• Fiber link status
• SFP vendor and model*
• Media converter temperature*
• TX/RX power*
Also, use SNMP to enter network commands that:
• Turn ON/OFF the media converter
• Turn ON/OFF the SFP ports
See the on-line documentation that comes with Transition Networks
FocalPoint™ software for applicable commands and usage at
www.transition.com.
* Some third-party manufacturers of SFP modules might not provide these
features in their product. If this is the case, the FocalPoint™ software will not
display these features.

Diagnostic Monitoring Interface (DMI)
The following DMI port screen and explanation table contains brief definitions of
the DMI support offered on Transition Networks SFP optical interfaces. For further
information, please see the help option on the CPSMM-xxx SNMP agent or Focal
Point, Transition Networks' GUI.
Variable Name Description
DMI Rx Power Measured Receive optical power in microwatts and in
decibels relative to 1mW.
DMI Rx Power Alarm Alarm status of measured Receive optical power.
DMI Temp Internally measured temperature of transceiver in degrees C
and degrees F.
DMI Temp Alarm Alarm status for internally measured temperature of
transceiver.
DMI Bias Current Measured transmit bias current in microamperes.
DMI Bias Alarm Alarm status for measured transmit bias current for the
interface.
DMI Tx Power Measured transmit power, in microwatts and in decibels
relative to 1mW..
DMI Tx Power Alarm Alarm status of measured transmit power.
Rx Power Intrusion
Threshold
Instructs the converter to stop passing traffic when the
receive power drops below the new threshold. This feature
is sometimes referred to as 'Intrusion Detection,' since
tapping into a fiber to intercept traffic leads to a reduction
in receive power. This value can be entered in microwatts
or in decibels relative to 1mW.
Note: This feature is not available on all devices.

Troubleshooting
If the CFMFF4040-100 converter fails, isolate and correct the failure by
determining the answers to the following questions and taking the indicated
action:
1. Is the PWR (power) LED illuminated?
NO
• Ensure the converter is inserted properly into the chassis.
• Ensure the power cord is properly installed in the chassis and in the
grounded outlet.
• Ensure the grounded outlet provides power.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
YES
• Proceed to step 2.
2. Are both LK1 & LK2 LEDs (fiber link for ports 1 & 2) illuminated?
NO
• Ensure both SFP transceiver modules are properly inserted in the
converter.
• Check the fiber cables for proper connection.
• Verify that the TX and RX cables on the media converter are connected to
the RX and TX ports, respectively, on the other device.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
YES
• Proceed to step 3.
3. Is the LK1 LED (fiber link 1) flashing?
NO
• If there is no network activity on port 1, proceed to step 4.
• If there is network activity on port 1, disconnect and reconnect the fiber
cables to restart the initialization process.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
YES
• Proceed to step 4.
4 Is the LK2 LED (fiber link 2) flashing?
NO
• If there is no network activity on port 2, contact technical support.
• If there is network activity on port 2, disconnect and reconnect the fiber
cables to restart the initialization process.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
