Introduction
The GE Security MC100FX-TX-PoE 100Base-FX to 10/100Base-TX PoE Media
Converter is a great solution for remote network equipment deployment. It
integrates the following two networking technologies:
• Media Conversion: 100Base-FX to 10/100Base-TX
• Power over Ethernet: Power Sourcing Equipment (PSE), PoE Injector
Providing both PoE and Fiber Optical interfaces, the MC100FX-TX-PoE is ideal
for service providers, campuses and public areas requiring deployment of
PoE devices at wireless access points for IP-based surveillance cameras or IP
phones easily, efficiently and cost effectively.

Introduction
Thank you for purchasing the GE MC100FX-TX-PoE 10/100Mbps Ethernet
Twisted pair to 100Base-FX Fiber-optic PoE Bridge Converter. This converter
is used to convert one type media signal to other equivalent type. The two
type segments connect easily, efficiently and inexpensively. The converter
provides a Power over Ethernet power injector function, which is able to
drive one IEEE 802.3af compliant powered device.
About the Power over Ethernet Injector
The MC100FX-TX-PoE is an IEEE 802.3af Power over Ethernet Injector that
provides DC 48V over Ethernet cables (power supply not provided). The
MC100FX-TX-PoE IEEE 802.3af Power over Ethernet Injector inserts DC
Voltage into Cat.5 cable, allowing the cable between the Injector (MC100FXTX-PoE) and PoE PD (Powered Device) to transfer data and power
simultaneously. The maximum distance between the Injector (MC100FX-TXPoE) and PoE PD is 100 meters. When a MC100FX-TX-PoE is installed, it
combines the Ethernet digital data with power over the twisted pair cables
as an IEEE 802.3af Power over Ethernet Injector. The IEEE 802.3af Power over
Ethernet splitter can separate the digital data and the power into two
outputs.
NOTE: This product is intended to be supplied by a UL Listed Direct Plug-In
Power Unit marked "Class 2" or "LPS" and output rated 48 VDC, 380 mA
minimum.

Chapter 1: Introduction
When an IEEE 802.3af Power over Ethernet device is installed the system
administrator only has to use a single RJ-45 Ethernet cable to carry both
power and data signals to each device.

The LFP function includes the Link Fault Pass Through function (LLCF/LLR) in
the DIP Switch design. LLCF/LLR can immediately alarm administrators to
problems of linked media and provide efficient solutions to monitor the net.
The DIP Switch settings can disable or enable the LFP function.

Chapter 1: Introduction
LLCF (Link Loss Carry Forward) means that when a device is connected to
the converter and the TP line losses it’s link, the converter will cease
transmitting. LLR (Link Loss Return) means when a device is connected to
the converter and the fiber line losses it’s link, the converter will cease
transmitting. Both can immediately alarm administrators of the problems of
the linked media and provide efficient solutions to monitor the network.
Link Loss Carry Forward (LLCF)
The MC100FX-TX-PoE incorporates an LLCF function for troubleshooting a
remote connection. When the LFP function is enabled, the FL/TP ports do not
transmit a link signal until they receive a link signal from the opposite port.
The diagram below shows a typical network configuration with a good link
status using the MC100FX-TX-PoE for remote connectivity.

If the connection breaks, the MC100FX-TX-PoE will send a link loss forward to
the switch or hub that generates a trap to the management station. The
administrator can then determine the source of the problem.

Link Loss Return (LLR)
The fiber ports of MC100FX-TX-PoE have been designed with an LLR function
for troubleshooting a remote connection. LLR works in conjunction with LLCF.
When the LFP function is enabled, the port's transmitter shuts down when its
receiver fails to detect a valid receive link. LLR should only be enabled on one
end of the link and is typically enabled on either end of the unmanaged or
remote device.
The diagram below shows a typical network configuration with good link
status using MC100FX-TX-PoE for remote connectivity. Note that LLR and
LLCF are enabled as indicated in the diagram.

If one of the optical conductors is bad (as shown in the diagram box below),
the converter with the LLR function enabled will return a no-link condition to
its link partner. The no-link condition is also carried forward to the switch or
hub where the trap was generated to the management station. The
administrator can then determine the source of the loss.

Installation
Installing the Converter
Please follow these steps to install the PoE Media converter:
1. Turn off the power of the device/station in a network to which the
MC100FX-TX-PoE will be attached.
2. Ensure that there is no activity in the network.
3. Attach a fiber cable from the MC100FX-TX-PoE to the fiber network. TX,
RX must be paired at both ends.
4. Attach a Cat. 5 UTP cable from the 10/100Base-TX network to the RJ-45
port on the MC100FX-TX-PoE.
5. Connect a 48V DC power adapter (not supplied) to the MC100FX-TX-PoE
and verify that the Power LED lights up.
NOTE: This product is intended to be supplied by a UL Listed Direct Plug-In
Power Unit marked "Class 2" or "LPS" and output rated 48 VDC, 380 mA
minimum.

PoE functions
The MC100FX-TX-PoE and the IEEE 802.3af Injector/Splitter installation:
Before installation, we recommend that you verify your network
environment. If there are any IEEE 802.3af devices that need power, then the
MC100FX-TX-PoE can provide power for this Ethernet device. The MC100FXTX-PoE can use an AC-DC adapter (not supplied) with DC 48V input and
injects this DC power into the pin of the twisted pair cable (pair 1, 2 and pair
3, 6).
NOTE: This product is intended to be supplied by a UL Listed Direct Plug-In
Power Unit marked "Class 2" or "LPS" and output rated 48 VDC, 380 mA
minimum.
If it is very difficult to find a power socket for AC-DC Adapter for your nonIEEE 802.3af networked device, the MC100FX-TX-PoE and SP-PoE can provide
you a way to supply DC power for these Ethernet devices conveniently and
easily.
