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.

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)

5EnhancedFeatures
Link Fault Signaling (LFS)
LFS is a “nice to have”function that is extremely
beneficial in termsofnetworkstatus monitoring.When
the Converteris connected between two nodes bya
singlelink, the LFSLEDwillimmediatelylightto
indicate when the link has been severed or when
someother causeof disruption in service has
occurred. The LFS function monitors both copper and
fiber segments giving a total connection status report.
The LFS featureinfluences bothfiber and copper
segments. Therefore, when disruption occurs on
either segment, the LFSfeature willbe activated and
the LEDwilllight to indicate thatthe entire link is down.
Deactivatethis function when performing the
Loopback diagnostics test.
The Converter is designed to behaveas thought two
converters are amalgamated into one. When the
Redundant function is activated,and “always-on”
connection willexist,and the Spanning Tree protocol
of aswitch willautomaticallydetermine the direction
for packets to be sent.
Warning
Deactivate the LFS function when the
Redundant function is active.

LoopbackTest
This Converter features aloopback test function.Use
the loopback test to checkif the fiber segment is
connected properlyalong the fiber segment loop. The
signals are bounced backto the sender fromthe
opposite media converter. Please see Diagrambelow:
Please make sure that the cables are connected
properlybefore getting started, and follow therules
given below:
1 Disable NWayAuto-negotiation
2 Set speed to 100Mbps
3 Set duplexmode to Full
4EnableLoopback Test
Launch aloopback or diagnostics testing program and
follow the instructions given. Typically,the instructions
willbe similar to the following:
a. Enterthe number of test messages
(framepackets) to be sent (Between 1 –
1000)
b. Click on the START button

NWaySetting
Note:FactoryNWayAuto-negotiation defaultset to
ON position.
ON: Activates NWayauto-negotiation operation
mode. SetNWayto ON when connecting to
an auto-negotiation device. The function will
automaticallydetermine the highest possible
speed and duplexmode inbothcopper and
fiber segments.
OFF: Deactivates NWayauto-negotiation operation
mode. Set NWayto OFF when connecting to
an auto-sensing device that onlysupports
10/100 detection. Someearlydevices only
support auto-sensing of speed, and NOT auto
detection of speed and duplexmode (auto-
negotiation).
Important:
In order to configure speed and duplex modes,
disable auto-negotiation
Setting the duplex mode is feasiblewhile the
media converter is “on-line”
Managed 2-port 10/100 to 100FX Standalone Converter
-22-
Configuring a Redundant Link
The redundant(or secondary)link works bybuilding a
second connection using another setof two copper
and fiber cables. This ispossible because the
Converter features two copper and two fiber
connectors. So altogether, we are utilizing all four
ports to build aprimaryand redundant link.
The redundant link feature is possiblebecause of the
IEEE 802.1d Spanning Tree protocolof aswitch.
When there isadisruption inthe primarylink, the
switch willautomaticallysend data via the redundant
link untilthe primarylink isrestored. Therefore, the
benefit of having aredundant link is that the
connection will always be on.
