OVERVIEW
Thank you for choosing the 1000Mbps Gigabit Ethernet Media
Converter, The Converter introduced here provides one channel
media conversion between 1000Base-TX and 1000Base-SX/LX.
About Media Converter
This Smart Media Converter WGT-702 utilizes a network
technology specied by IEEE802.3ab and IEEE802.3z 1000BaseT/LX/SX standards.
About Link Pass Through
When LLCF (Link Lose 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 Lose Reture) 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 card 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
WGT-702 will be attached
Step 2- Ensure that there is no activity in the network
Step 3- Attach ber cable from the WGT-702 to the ber
network.
Step 4- TX, RX must be paired at both ends
Step 5- Attach a Cat. 5 UTP cable from the 1000Base-T Network
to the RJ-45 port on the WGT-702.
Step 6- Connect the 7.5VDC power adapter to the WGT-702 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 accepted
� 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.

MANAGE MEDIA CONVERTER
The Intelligent Media Converter Chassis that can control WGT-702
through the management system, this WGT-702 can be controlled
through Web Browser, SNMP management utility and terminal
emulation program.
The Intelligent Media Converter Chassis will detect the setting on
the DIP switches and display out the status, also the Chassis can
control the function through the maanagement system.

LINK PASS THROUGH FUNCTION
Link Loss Carry Forward (LLCF)
When a device connected to the converter and the TP line loss the
link, the converter’s ber will disconnect the link of transmit, so
that the other ends will know that there is a linkage error on this
end. And when the Fiber line loss the link, the converter’s TP will
disconnected, and the other end will know that there is linkage
problem exist.
The default LLCF setting on WGT-702 is ON.
The diagram below shows a typical network conguration with a
good link status using WGT-702 for remote connectivity.
If the connection breaks, WGT-702 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.

Link Loss Return (LLR)
The ber ports of WGT-702 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 WGT-702 for remote connectivity. Note that
LLR is enabled as indicated in the diagram.
If one of the optical conductors is bad (as shown in the diagram
box below), WGT-702 with LLR enabled will return a no-link
condition to its link partner. With LLCF default, 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).
