2HardwareDescription
The Converter was especiallydeveloped for mission
critical applications such as financial institutions, e-
commerce, Hospitals, and the Military.The device
comes with2copper and2fiber ports that provide
10/100Basefiber-to-copper conversion. With this
design, aPrimaryand aredundant link can be
configured to ensure an "always-on" connection exists,
eliminating costlynetwork downtime. Being SNMP-
ready,the Converter enable network managers to
remotelymonitorthe entire network status quicklyand
easilyvia RJ-45 (in-band),or RS-232 (out of band)
connection to the 'master' module.This managed
media converter can extend the enterprise LAN
configuration range up to 60km while simultaneously
minimizing the timetroubleshooting. The Converters
are designed as'plug-n-play',and for hassle-free
integration in today's managed mixed cabling network
configurations.
Featuring auto MDI/MDI-X detection for direct
connection to aworkstation, switch or hub, network
managers no longer need toworryabout the cable
configuration (crossover or straight through) when
establishing connection between RJ-45 ports.

The enhanced capabilities of the Converter include
Link FaultSignaling (LFS),Loopback Test (LBK) and
auto-negotiation. The LFSfeature allows constant
connectivitybydiverting the data transmission to a
redundant link when abreakdown or error exists
anywhere along the link. The LBK gives an
administrator instant connectivityinformation from
either the local or remote side.
The Converterhas Auto-Negotiation capabilities that
allow itto supportconnection with leading NWay
switches. In full duplexmode, this unit can sustain
distances of up to 2kilometers for multi-mode fiber
and 60 kilometers for long haulsinglemode fiber
between aLANswitch and another switch or file
server.
This Converter features bothRJ-45 jacks and
ST/SC/WDM fiber optic connectors thatallow it to
connect a10/100Base-TX network to a100Base-FX
(fiber-based) network.

Connectors
This Converter utilizes portswithfiber or copper port
connectors functioning under Ethernet and/or Fast
Ethernet protocols.
10/100BASE-TX Ports
The 10/100BASE-TX portssupports network speeds
of either 10Mbps or 100Mbps, and can operatein half-
and full duplextransfer modes. The ports also offer
automatic MDI/MDI-X crossover detection that gives
true “plug and play”capability - just plug-in the
network cables tothe ports and the ports willadjust
according to end node devices. The RJ-45
connectors are suitable for UTP cable Category3,4,
5 or better.

100BASE-FX Ports
The 100BASE-FX ports add fiber Fast Ethernet links
to your network device. Compliant with IEEE 802.3u,
these ports can transmit dataat100Mbps infull
duplexmode across distances of up to 2kmover
multi-mode fiber-optic cable. The fiber ports havea
choice of three fiber connector types: ST, SC and
WDM.

3Installation
The location selected toinstall the Converter may
greatlyaffect its performance. When selecting asite,
we recommend considering the following rules:
•Installthe Converter in afairlycool and
dryplace. See Technical Specifications
for the acceptabletemperature and
humidityoperating ranges.
•Installthe Converter in alocation free
fromstrong electromagnetic field
generators (such as motors), vibration,
dust, and direct exposure tosunlight.
•Leaveat least 10cmof space at the front
and rear of the unit for ventilation.
•Affixthe provided rubberpads to the
bottomof the Converter toprotect the
case from scratching.

Desktop Installation
Follow the instructions listed below toinstallthe
Converter onto adesktop location.
1. Locate the Converter in aclean,flat and safe
position thathas easyaccess to AC power.
2. Affixthe four (4) self-adhesiverubber pads to
the underside of the Converter.
3. ApplyAC power tothe Converter. (The green
PWR LED on the front panel should light).
4. Connect cables fromthe network partner
devices to the ports on the front panel.(The
green LNKLEDon module front panel
associated with the port should light).
This Converter can also be mounted on avertical
surface. Simplyuse the underside of the unit as a
template tomeasure and markout the position of the
holes on to the surface where the unit is to be
installed. Then use the two screws provided tomount
the Converter firmlyin place.
Warning Because invisible laser radiation may
be emitted fromthe aperture of the port when no
cable is connected,avoidexposure to laser
radiation and do not stare into open apertures.

Getting Connected
This Converter is capableof connecting 4network
devices employing acombination of twisted-pair and
fiber cabling paths atEthernetor Fast Ethernet
speeds.
PoweringOn Unit
The Converter uses an AC power supply 100~240V
AC, 50~60 Hz.The poweron/offswitch is located at
the rear ofthe unit adjacent to the AC power
connector and the systemfans. The Converter s
power supplyautomaticallyself-adjusts to the local
power source and maybe powered on withouthaving
anyor all LANsegment cables connected.
1. Insert the power cable plug directlyintothe
receptacle located at the back ofthe device.
2. Plug the power adapter into an available
socket.
Note: For Internationaluse,you mayneed tochangethe
ACpower adapter cord. Youmust use apower
cord setthat has beenapprovedforthe
receptacle type and electricalcurrent inyour
country.
3. Check the front-panel LEDsas the device
is powered on to verifythatthe Power LED
is lit.If not, check that the power cable is
correctlyand securelyplugged in.

Connecting FiberCable
When connecting fiber cable to a100BASE-FX port
on the Converter, be sure the correct type –ST,SC or
WDM-connector is used.Follow the steps below to
properlyconnect fiber cabling:
1. Removeand keep theST/SC/WDM ports
rubber covers.When notconnected to a
fiber cable,the rubbercovershould be
replaced to protect the fiberoptics.
2. Check that the fiber terminators are clean.
You can clean the cable plugs bywiping
themgentlywithaclean tissue orcotton
ballmoistened withalittleethanol.Dirty
fiber terminators on fiber optic cables will
impair the qualityof the light transmitted
through the cable and lead to degraded
performance on the port.
3. Connect one end of the cable to the
ST/SC/WDM port on the Converter and the
other end tothe ST/SC/WDM port on the
other device.
Note: When inserting the cable, be sure the tab on the plug
clicks into position to ensure thatit isproperlyseated.
4. Check the corresponding port LED on the
Converter to be sure that the connection is
valid. (Refer to the LEDchart innext
section)

Connecting CopperCable
The 10/100BASE-TX RJ-45 Ethernet port fully
supportsauto-sensing and auto-negotiation.
1. Insert one end of a Category3/4/5/5e type
twisted pair cableinto an availableRJ-45 port
on the Converter and the other end into the
port of the network node.
2. Check the corresponding portLEDon the
Converter to be sure thatthe connection is
valid. (Refer to LED chart in nextsection)
