Chapter 1 OVERVIEW
Thank you for choosing the Smart 10/100Base-TX to 100Base-
FX Media Converter, The Media Converter introduced here
provides one channel media conversion between 10/100Base-TX
and 100Base-FX.
About the Redundant Media Converter
The FT-1105A and FT-1205A are 3-Port Redundant Media
Converters which support conversion between 10/100Base-
TX and 100Base-FX network. Different with the other one-port
channel media converter, the Redundant Media Converters are
designed for critical networks that require fiber or copper link
auto recover less than 10ms, such as ISP, telecom, hospital,
banking and enterprise. The two models of PLANET Redundant
Media converter as following:
● FT-1105A: 10/100Base-TX copper to two 100Base-FX fiber
link redundancy
● FT-1205A: 100Base-FX to two 10/100Base-TX copper link
redundancy
Via the built-in DIP-switches, the two models can be configured
as 3-Port Ethernet switch or 2-Port Redundant media converter.
With the 3-Port switch mode, they work in high performance
Store and Forward mechanism, also can prevent packet loss
with IEEE 802.3x Flow Control (Full-Duplex) and Back Pressure
(Half-Duplex).
With 2-Port redundant Mode, it provides less than 10ns
link redundancy for highly critical Ethernet applications.
The redundant-mode supports auto-recover function. If the
destination port of a packet is link down, it forwards the packet
to the other port of the backup pair.
The Redundant Media Converters - FT-1105A and FT-1205A,
support conversion between 10/100Base-TX and 100Base-FX

network. The SFP slot supports single-mode, multi-mode and
WDM small-form factory type transceiver modules for your
needs. With 100Base-FX SFP ports, the FT-1105A and FT-1205A
are with high reliability and flexibility to extend the distance up
to 2Km, 20Km, or longer. It depends on the 100Base-FX SFP
transceiver modules.
Ethernet signal that allows two type segments connect easily,
efficiently and inexpensively.
The converters can be used as a stand-alone unit or as a slide-
in module to the PLANET Media Converter Chassis (MC-700,
MC-1000R and MC-1500). As the other PLAENT FT-Series
media converters, they’re hot swappable in MC-Chassis.

Chapter 6 INSTALLING THE CONVERTER
6.1 Stand-alone Installation
FT-1105A / FT-1205A is with high reliability and flexibility to
extend the distance up to 2Km, 20Km, or longer. It depends on
the 100Base-FX SFP transceiver modules. The SFP transceivers
are hot-pluggable and hot-swappable. You can plug-in and out
the transceiver to/from any SFP port without having to power
down the converter.
To install a FT-1105A / FT-1205A stand-alone, on a desktop or
shelf, simply complete the following steps:
Step 1: Turn off the power of the device/station in a network to
which the FT-1105A / FT-1205A will be attached.
Step 2: Ensure that there is no activity in the network.
Step 3: Slot in the 100Base-FX SFP. Make sure both side
of the SFP transfer are with the same media type,
for example: 100Base-FX/2km to 100Base-FX/2km,
100Bas-FX/20km to 100Base-FX/20km.

It recommends using PLANET MFB-FX series
100Base-FX SFP on the converter. If you insert
a
SFP transceiver that is not supported, the
Note
converter will not recognize it.
Step 4: Connect the fiber cable. Attach the duplex LC connector
on the network cable into the SFP transceiver.
Step 5: Attach fiber cable from the FT-1105A/FT-1205A to the
fiber network. TX, RX must be paired at both ends.
Step 6: Connect the 5VDC power adapter to the FT-1105A/FT-
1205A and verify that the Power LED lights up.
Step 7: Turn on the power of the device/station; the PWR LEDs
should light when all cables are attached.
Please refer to APPENDIX-A for detailed wiring
information of the FT-1105A/FT-1205A.
To prevent from optic acceptor malfunction, check
the both wires / transmitter before power on the
converter.
Note
6.2 Chassis Installation and Rack Mounting
To install the media converter in a 10-inch or 19-inch with
standard rack, follow the instructions described below.
Step 1: Place your FT-1105A/FT-1205A on a hard flat surface,
with the front panel positioned towards your front side.

Step 2: Carefully slide in the module until it is fully and firmly
fitted into the slot of the chassis.
Figure 2-1: Insert a media converter into an available slot
Step 3: Attach a rack-mount bracket to each side of the Chassis
with supplied screws attached to the package.
Step 4: After the brackets are attached to the chassis, use
suitable screws to securely attach the brackets to the
rack, as shown in Figure 2-2.
Step 5: Proceed with the steps 4 and steps 5 of session 6.1
Stand-alone Installation to connect the network
cabling and supply power to your chassis.
You must use the screws supplied with the
mounting brackets. Damage caused to the parts
by using incorrect screws would invalidate your

FT-1205A provide less than 10ms link
redundancy for highly critical Ethernet applications. The
redundant-mode supports auto-recover function. If the
destination port of a packet is link down, it forwards the packet
to the other port of the backup pair. The following figure shows
the redundant function.

Chapter 8 Loop Back Reply
The FT-1105A / FT-1205A supports auto loop back reply while
receive loop back test packets on fiber port. Enable this function
to tell the converter to reply fiber signals request from Web
Smart media converter, such as PLANET FT-90x. You can use
this to check whether the converter can communicate with
partner converter. Please refer to the following figure.
For FT-1105A only, while enable the Loop Back
Reply function, the Port-2 (TP) must be link up.
