2 CHANNEL 10/100 MBPS ETHERNET
ELECTRICAL TO OPTICAL MEDIA CONVERTER
WITH OPTIONAL POWER OVER ETHERNET (POE+)
The ComNet Ethernet CNFE200(X) media converter series are two-channel Ethernet
electrical to optical media converters with optional PoE+. These auto-negotiating
devices accept two 10/100 Mbps electrical inputs and convert this to a single 100
Mbps optical output. This series of media converters are available as multimode
or single-mode and one and two fiber SC and ST optical connectors. The ComNet
exclusive Demux feature allows for port isolation, replicating two media converters
over one fiber. The ComNet exclusive Mux feature prevents network video flooding
of multicast traffic with DIP switch selection of the fiber port as a dedicated uplink
path. The CNFE200(X) series can be powered by wide range AC or DC input while the
CNFE200(X)POE units meet the 802.3at standard and provide 30 watts of PoE+ power,
with an option for a 60 watt CNFE200(X)POEHO model. The PoE models are powered
by a 48 to 56 volt DC power supply (sold seperately).
LED indicators confirm operational status. All models are environmentally hardened
with no electrical or optical adjustments (Plug and Play). DIP Switches on the outside of
each unit allow for fine-tuning of features. See Figures 1 – 14 for complete operation
details. See Figures A and B for mounting instructions.

The fault relay is normally closed and will open on any of the following alarm conditions:
- Link Fault is enabled on the remote CNFE200(X) unit and a copper port has been disconnected.
- Link Fault is enabled on the local CNFE200(X) unit and a copper port has been disconnected.
- Fiber Fault is enabled on the local CNFE200(X) unit and the fiber link is down or the power has been lost to
either the local or remote CNFE200(X) unit.

MECHANICAL INSTALLATION INSTRUCTIONS
INSTALLATION CONSIDERATIONS
This fiber-optic link is supplied as Standalone/Surface Mount and Surface
Mount/Rack Mount modules. Units should be installed in dry locations
protected from extremes of temperature and humidity.
C1-US, C1-EU, C1-AU or C1-CH Card Cage Racks
CAUTION: Although the units are hot-swappable and may be installed
without turning power off to the rack, ComNet recommends that
the power supply be turned off and that the rack power supply is
disconnected from any power source. Note: Remove electrical connector
before installing in card cage rack.
1. Make sure that the card is oriented right side up, and slide it into the card
guides in the rack until the edge connector at the back of the card seats in
the corresponding slot in the rack’s connector panel. Seating may require
thumb pressure on the top and bottom of the card’s front panel.
FIGURE A
Dimensions are for a standard ComNet one slot module
CAUTION: Take care not to press on any of the LEDs.
2. Tighten the two thumb screws on the card until the front panel of the
card is seated against the front of the rack.
WARNING: Unit is to be used with a Listed Class 2 power supply.
IMPORTANT SAFEGUARDS:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is not
compromised.
