OVERVIEW
Thank you for choosing the Smart 10/100TX to 100FX Media
Converter, The Media Converter introduced here provides one
channel media conversion between 10/100TX and 100FX.
About Media Converter
The Smart Media Converter utililizes a network technology
specied by IEEE802.3 10Base-T, IEEE802.3u 100Base-TX,
100Base-FX standards.
About Link Pass Through
When LLCF (Link Loss Carry Forward) is enabled, the ports do
not transmit a link signal until they receive a link signal from the
opposite port. Link loss is “carried forward” to the managed switch
or hub that is sending the link. LLCF can be used for either the
copper or ber ports.
When LLR (Link Loss Return) is enabled, the ber port’s
transmitter shuts down if its receiver fails to detect a valid receive
link. If one of the optical conductors is bad, the converter with LLR
enabled will return a no link condition to its link partner. LLR is
used to detect link problems only on the ber port.

INSTALLING THE CONVERTER
6.1 Used as a Stand-alone converter
Step 1- Turn off the power of the device in a network to which
the WFT-80X will be attached
Step 2- Ensure that there is no activity in the network
Step 3- Attach ber cable from the WFT-80X to the ber
network.
Step 4- TX, RX must be paired at both ends
Step 5- Attach a Cat. 5 UTP cable from the 10/100 Base- TX
network to the RJ-45 port on the WFT-80X.
Step 6- Connect the 7.5VDC power adapter to the WFT- 80X and
verify that the Power LED lights up.
Step 7- Turn on the power of the device, the TX Link and FX
Link LEDs should light when all cables are attached
NOTE:
• RJ-45 Cat 5, straight-through cable is ac-
cepted
• Please refer to Chapter 10 for more about
the wiring distance of your TP, Optic-fiber
networks.

6.2 Used with WMC-1600R converter chassis
Step 1- Unscrew and pull out the media converter board
Step 2- Remove a blank faceplate from an empty expansion slot
on the front of the chassis. The module can be installed in
any expansion slot.
Step 3- Slide the module into the expansion slot, aligning it with
the guiderails, until it rmly connects to the chassis’
backplane.
Step 4- Secure the module to the chassis by tightening the
thumbscrew.

LINK PASS THROUGH FUNCTION
Link Loss Carry Forward (LLCF)
Smart Media Converter modules incorporate an LLCF function for
troubleshooting a remote connection. When LLCF 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 conguration with
a good link status using Smart Media Converter for remote
connectivity. Note that LLCF is enabled on DIP switch.
If the connection breaks, the Smart Media Converter that link
loss forward to the switch/hub which generates a trap to the
management station. The administrator can then determine the
source of the problem.
IMPORTANT: When connecting the Smart Media Converter
with LLCF enabled to an auto-negotiating-capable device, force both sides of the configuration to 10 or 100Mbps full or half duplex.
This allows the converter to immediately see
link pulses and start passing data.
* Units are shipped with the LLCF function disabled.
EM_WFT8v2.indd 2004/11/5, �� 11:3211

Link Loss Return (LLR)
The ber ports of WFT-80X have been designed with an LLR
function for troubleshooting a remote connection. LLR works in
conjunction with LLCF.
When LLR 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
the unmanaged or remote device.
The diagram below shows a typical network conguration with
a good link status using Smart Media Converter 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 LLR enabled will return a no-link
condition to its link partner. With LLCF also enabled, the no-link
condition is carried forward to the switch/hub where a trap is
generated to the management station, and the administrator can
then determine the source of the loss.
IMPORTANT: LLR must NOT be active on both ends of a
configuration. If it is, the link can never be
established.
*Units are shipped with the LLR function disabled (DOWN).
