The ComNet™ CNFECL1MC(-M) is an environmentally hardened modem that
supports Ethernet over twisted pair or coaxial cable. The devices use VDSL
(EoVDSL) technology to support data rates up to 90 Mbs. Ethernet data may be
transmitted over a telephone-grade twisted copper pair, legacy serial cabling
or standard 75Ω coaxial cable circuits. These modems allow for upgrading of
a legacy twisted copper or coaxial cable plant for use with Ethernet rather than
installing new network cabling.
The fastest usable data rate is automatically selected, depending upon
the transmission distance and cable quality. The CNFECL1MC(-M) may be
deployed in most out-of-plant installations, such as those found in intelligent
transportation systems and factory automation/control applications. LED status
indicators are provided for rapidly ascertaining the operating status of the
modem and the link.
See Figures 1 – 8 for complete installation details.
The CNFE1CL1MC standard size unit may be directly plugged into the ComNet
Rack (Part C1) or operated as a standalone module. The CNFE1CL1MC-M
small size unit operates as standalone module only. See Page 5 for mounting
instructions.

This fiber-optic link is supplied as a Standalone/Rack module. 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.
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 or LPS 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 (T
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.
