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 then 10ms, such as ISP, telecom, hospital, banking and
enterprise. The two models of PLANET Redundant Media converter
as following:
FT-1105A: 100Base-FX to two 10/100Base-TX copper
link redundancy
FT-1205A: 10/100Base-TX copper to two 100Base-FX
fiber link redundancy
Via the build-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 (HalfDuplex).
With 2-Port redundant Mode, it provides less than 10ms link
redundancy for highly critical Ethernet applications. The redundantmode 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.

DIP SWITCH
There is a DIP switch for the setting on converter mode of copper
and fiber port. Refer to the table below for more details.
FT-1105A
Switch 1 On 2-Port Redundant (TP)
Off 3-Port Switch ( default )
Switch 2
On LBR ON
Off LBR OFF ( default )
2-Port Redundant ( FT-1105A)
When TP Redundancy is enabled, TP Port-2 and TP Port-3 are
configured as either forwarding or disabled. At any given time,
one port will be disabled and one port will be forwarding.
3-Port Switch
When TP Redundancy is disabled, all ports (Port-1, Port-2 and
Port-3) act as normal bridging ports.

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-plugable 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.
8
NOTE:
It recommends using PLANET MFB-FX series
100Base-FX SFP on the converter. If you insert
a SFP transceiver that is not supported, the
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.
NOTE:
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.
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.
9
Step 2: Carefully slide in the module until it is fully and firmly
fitted into the slot of the chassis.
Figure 6-2: 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 6-2.
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 switch.
Caution:
You must use the screws supplied with the mounting
brackets. Damage caused to the parts by using
incorrect screws would invalidate your warranty.

Chapter 7
Redundancy
The FT-1105A / FT-1205A provide less than 10 ms 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.
• Link status auto detect and redundant on Dual ports with
same connector type.
• Only Primary-Port is active at a time, the Backup-Port is
blocked.
• While Primary-Port link fail occur, the traffic swap to
Backup-Port automatically.
• Once the Primary-Port status back to link up, the traffic
swap from Backup-Port to Primary-Port.

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.
Notice:
For FT-1105A only, while enable the Loop Back
Reply function, the Port-2 (TP) must be link up.
