MC252-1P-1CX. If connects with Non-PoE coax-LAN equipment, it might
cause the equipment to damage.

2. INSTALLATION
This section describes the functionalities of the Industrial Power over Coaxial Extender’s components
and guides you to how to install it on the desktop. Basic knowledge of networking is expected. Please
read this chapter completely before continuing.
2.1 Product Description
Power over Coaxial
Based on IEEE 802.3at high power over Ethernet and up to 30 watts of power output, IFS PoE over
coaxial extender solution eliminates the need for additional remote site power while allowing a single PoE
source, such as a PoE network switch, to provide power to both transceivers and the camera at long
range. This feature eliminates the need for local and remote site power supplies.
IEEE 802.3at/af PoE Injector and Splitter in one box design
The MC252-1P-1CX is a Single-Port, 802.3at High Power over Ethernet Injector providing maximum up
to 30 watts of power output over Ethernet cable which allows data and power to transmit simultaneously
through the cable to PoE PD (Powered Device). In addition, the MC252-1P-1CX also features PoE
splitter function with selectable 12V/24V DC power output which makes non-PoE equipment power up as
well.
Stable Operating Performance under Difficult Environments
The MC252-1T-1CXP and MC252-1P-1CX extender is the perfect solution for extended distance data
and power transmission for warehouses, parking lots, campuses, casinos, and many more. They can
operate stably under temperature range from -40 to 75 degrees C which enables the users to
conveniently apply the device in almost any location of the network.

Front Panel DIP Switch Setting
The front panels of the MC252-1T-1CXP and MC252-1P-1CX provide one 2-DIP switch which is for
configuring coaxial link CO/CPE mode and Band plan function.
Refer to the table below to know about the 2-DIP switch settings and descriptions:
DIP-1 DIP-2
Mode Band Plan
OFF CO Symmetric
ON CPE Asymmetric
Symmetric means upstream and downstream rate are similar and Asymmetric means upstream and
downstream rate are not the same. The CO mode stands for Central Office (meaning the switch side)
and CPE mode is for Customer Premises Equipment (meaning camera side)

2. MC252-1T-1CXP has two power input options; only one mode is available at
one time. It cannot use PoE power input if power input of DC 52V or 56V is
selected.

1. Please ensure the MC252-1P-1CX output voltage is correct for remote
device.
2. Please plug off the PoE Coaxial cable from MC252-1P-1CX before switching
off the Power Voltage DIP during operation. Wait for 3 seconds until the “PoE
IN” LED is completely OFF. Otherwise, it might damage your devices.

As the MC252-1T-1CXP is power over coaxial, please confirm
that other Non-PoE equipment is not connected with the
coaxial cable. When you connect the coaxial cable with
coax-LAN converter, CCTV camera, etc, it might cause other
equipment to damage.

3. TROUBLESHOOTING
This chapter contains information to help you solve issues. If the Industrial Power over Coaxial Extender
is not functioning properly, make sure the Industrial Power over Coaxial Extender was set up according
to instructions in this manual.
VDSL LNK LED does not light after wire is connected to the VDSL port.
CHECKPOINT:
1. Verify the length of the wire connected between MC252-1T-1CXPand MC252-1P-1CX.
It should not be more than 2.4km.
2. Please note you must use one for CO mode and the other with CPE mode, and connect
to each other to make it work.
TP LED does not light after cable is connected to the port.
CHECKPOINT:
1. Verify you are using the Cat.5, 5e or 6 cables with RJ-45 connector to connect to the
port.
2. If your device (like LAN card) supports Auto-Negotiation, please try to manually modify
at a fixed speed of your device.
3. Check whether the power of the converter and the connected device is ON or OFF.
4. Check the port’s cable is firmly seated in its connectors in the switch and in the
associated device.
5. Check the connecting cable is good.
6. Check the power adapters are functional, including the connecting device.
Available Bandwidth is less than expected
CHECKPOINT:
The actual data rate will vary on the quality of the coaxial cable and environment factors.
My POE PD Device doesn’t get power when connected to MC252-1P-1CX?
CHECKPOINT:
1. Please check and assure the device is fully complied with IEEE 802.3af / IEEE 802.3at
standard
2. Please check the cable type of the connection from MC252-1P-1CX to the other end. The
cable should be an 8-wire UTP, Category 5 or above, and EIA568 cable within 100
meters. A cable with only 4-wire, short loop or over 100 meters will affect the power
supply.
