The ComNet™ CopperLine® CLFE(X)UTP Ethernet over UTP line consists of four
models that support 100Mbps Ethernet as well as Pass-through Power over Ethernet
(PoE) over twisted pair cable (CAT5, UTP). These models support transmission
distances of up to 3,000 feet (914m) at 10 Mbps, or 2,100 feet (640m) at 100 Mbps.
The CLFE1UTP, the CLFE4UTP, CLFE8UTP and the CLFE16UTP transport, one, four,
eight or sixteen channels respectively. The IEEE 802.3-compliant Ethernet electrical
interface of these Ethernet extenders also meets the requirements for IEEE 802.3af
PoE power, passing-through up to 30 watts of power per port to the powered device
(PD). The CLFE(X)UTP series may also be used interchangeably with other CopperLine
Ethernet-over-UTP extenders.

Environmentally hardened to the requirements of NEMA TS-1/ TS-2 for most out-of­plant applications, and true plug-and-play design ensures ease of installation and
operation.

LED indicators are provided for rapidly ascertaining the operating status of the
device. See Figures 6 – 8 on Page 7 for LED explanations.

Packaged in a rugged aluminum housing, these units are designed for desktop or stand­alone mounting. The CLFE8UTP and CLFE16UTP are offered in EIA 19” 1U high rack for
easy installation. See Figures A through C on Page 8 for mounting instructions.

See Figures 1 – 8 for complete installation details.

PASS-THROUGH PoE OPERATIONS FOR THE CLFE1UTP

ComNet’s CopperLine CLFE1UTP extended distance IP data and PoE maintains the safety standards for communications found
within the 802.3af PoE standards. This is for the protection of products operating in the extended distance transmission chain. In the

event of malfunctions the communication system is designed to shut down power transmission to avoid device damage.

The CLFE1UTP can be powered by a local power source (12 Volts D.C. or 24 Volts A.C.) or from a single PSE source, such as a
network switch’s PoE port using its unique Pass-through PoE feature (4-pair mode only). This latter feature eliminates the need for
CLFE1UTP local power while also providing power for the camera (See full installation instructions, Page 6).

Powering The CLFE1UTP Transceivers

Input with
external power
plug installed.

Under normal operating conditions CLFE1UTP transceivers should be powered using the PoE source. External power to the
CLFE1UTP should be restricted to installations where a camera requires local power.

When installing the CLFE1UTP, the following conditions apply which will affect its operations.

The CLFE1UTP is provided with the ability to operate using a local external power supply. The standard accessory local power
adaptor plug can be used for power supplies that do not have the CLFE1UTP’s standard power input connector. When inserting
the adaptor into the power input, the CLFE1UTP is only powered from a local power source and not from a PSE source. The camera
will continue receiving power from the PSE source and operations will be normal.

However, if the external plug adaptor is inserted in the CLFE1UTP and no power is applied, the CLFE1UTP will not power up even
if a PoE source is present, the camera will continue to receive power. In this case the CLFE1UTP is not operational and no data will
flow.

If the CLFE1UTP is externally powered and PSE power is lost, power to the CLFE1UTP must be recycled in order for the PSE to
recognize the PD (Camera).
