INSTALLATION AND OPERATION MANUAL

CNFE1CL1MC(-M)

FAST ETHERNET OVER VDSL (EoVDSL)

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.

MECHANICAL INSTALLATION INSTRUCTIONS

INSTALLATION CONSIDERATIONS

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.
