OVERVIEW
Thank you for purchasing the PLANET Gigabit Ethernet Media
Converter products. The Gigabit Ethernet Media Converter
introduced here provides one channel media conversion between
the 1000Base-T and 1000Base-SX/LX, 1000Base-SX/LX through
SFP Mini-GBIC (Model: WGT-705A), or the 1000Base-LX WDM
(Model: WGT-706A15/B15).
The Gigabit Ethernet Media converter products can be used as a
standalone unit or as a slide-in module to the 19" intelligent media
chassis (up to 16 units) for a TP and Fiber combined networks at a
central wiring closet. Please contact with your sales representative
for more about the 19" intelligent media chassis.
About the Gigabit Ethernet Media Converter
The Gigabit Ethernet Media Converter utilizes a network
technology specied by IEEE 802.3ab 1000Base-T and IEEE
802.3z 1000Base-SX/LX standards. The Gigabit Ethernet Media
converter is used to convert one type media signal to other
type equivalent that allows two type segments connect easily,
efciently and inexpensively.
About Link Pass Through function
When LLCF 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 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.

MODEL LIST
Your Gigabit Ethernet Converter comes with one of the following
models.
• WGT-702 1000Base-T to 1000Base-SX (SC)
• WGT-702S 1000Base-T to 1000Base-LX (SC)
• WGT-705A Depend on the SFP Mini-GBIC module
capacity
• WGT-706A15 1000Base-T to 1000Base-LX (WDM)
• WGT-706B15 1000Base-T to 1000Base-LX (WDM)
 NOTE:
Please note WGT-706A15/ 706B15 is de-
signed to work together in pair. It means
you must connect WGT-706A15 to WGT-
706B15 from them to work normally. If both
ends are WGT-706A15 or WGT-706B15, they
can’t work normally and may damage the fi-
ber connectors.
In the following section, WGT-70x represents the models above
unless specied.

CHECKLIST
Your WGT-70x carton should contain the following items:
• The Gigabit Etherne Media Converter
• AC-DC Power Adapter (Output: 7.5VDC, 1.5 A max.)
• This user’s manual
If any item is missing or damaged, please consult the dealer from
whom you purchased your Gigabit Ethernet Media Converter, the
WGT-70x.

DIP SWITCH
There is a DIP switch for the setting on copper and ber port.
Refer to the table below for more details.
Switch 1
On Fiber is Forced Mode
Off Fiber is Auto-Negotiation
Switch 2
On LLR enable
Off LLR disable
 NOTE:
1. Be sure the opposite end is using the
same setting (forced or Auto-negotiation).
And when using two converters at the
same time, the two converters MUST set
to forced mode.
2. When using two converters, don t enable
the both device s LLR function at the same
time. Either one shall functional.

INSTALLING THE CONVERTER TO
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 firmly connects to the
chassis’ backplane.
Step 4- Secure the module to the chassis by tightening the
thumbscrew.

MANAGE THE MEDIA CONVERTER
The Intelligent Media Converter Chassis that can control this
Smart Media Converter through the management system, this
Smart Media Converter 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 Management
Chassis can control the function through the management
system.
 NOTE:
To control the function in a working station,
need to collocate together with Intelligent
Media

LINK 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
dis-connected, and the other end will know that there is linkage
problem exist.
There is a default LLCF setting on this converter.
The diagram below shows a typical network congu-ration with a
good link status using Smart Media Converter modules for remote
connectivity.
If the connection breaks, the Smart Media Converter modules 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 the Smart Media Converter have been designed
with an LLR function for trouble-shooting a remote connection.
LLR works in conjunc-tion 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 congu-ration with
a good link status using Smart Media Converter 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), the converter 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).
