Introduction
Thank you for choosing the 1000Base Gigabit Ethernet Media Converter,
The Converter introduced here provides one channel media conversion
between 1000BASE-T and 1000BASE-SX/LX through mini-GBIC
module.
About Media Converter
Media Converter is a network technology specified by IEEE 802.3ab
1000BASE-T and IEEE 802.3z 1000BASE-SX/LX standards.
Product Features
One-channel media conversion between 1000BASE-T and
1000BASE-SX/LX mini-GBIC
Fiber media allows: multi-mode fiber and single-mode fiber using
LC connector
Link Pass Through function
Auto negotiation of duplex mode on TX port
Auto MDI/MDI-X for TX port
Full wire-speed forwarding rate
Front panel status LEDs
Used as a stand-alone device or with a chassis
Hot-swappable when used with a chassis

Installation
This chapter gives step-by-step installation instructions for the
DMC-805G.
Selecting a Site for the Equipment
As with any electric device, you should place the equipment where it
will not be subjected to extreme temperatures, humidity, or
electromagnetic interference. Specifically, the site you select should
meet the following requirements:
1. The ambient temperature should be between 32 and 104 degrees
Fahrenheit (0 to 40 degrees Celsius).
2. The relative humidity should be less than 90 percent,
non-condensing.
3. Surrounding electrical devices should not exceed the
electromagnetic field (RFC) standards for IEC 801-3, Level 2
(3V/M) field strength.
4. Make sure that the equipment receives adequate ventilation. Do
not block the ventilation holes on each side of the switch or the
fan exhaust port on the side or rear of the equipment.
5. The power outlet should be within 1.8 meters of the switch.
Sliding Switch
There is a two pin DIP switch on the module which define as switch 1
and switch 2:
Switch 1: Fiber mode switch
When the switch was turned to “On”, it means that the fiber was
turned to forced mode, and “Off”for auto-negotiation mode.
Note: 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.
Switch 2: LLR
When the switch was turned to “On”, it means that the LLR was
enabled and “Off”for disabled.
Note: When using two converters, don’t enable the both devices’ LLR
function at the same time.

Switch 1 : On -> Forced Mode
Off -> Auto Negotiation mode
Switch 2 : On -> LLR enable
Off -> LLR disable
Installing in a Chassis
The Converter can be fit into any of the expansion slots on a special
designed chassis.
First, install the converter onto a carrier supplied with the chassis:
Step 1- Unscrew the carrier from the desired expansion slot on the
chassis.
Step 2- Remove the screw on the converter as shown below.
Step 3- Fit the converter onto the carrier and use the screw to secure
it.
Unscrew and pull out the
media converter board

Management the Media Converter
There is a management module that can control this media converter
through the chassis system, this media converter can be controlled
through Web Browser, SNMP and terminal emulation program.
The management module will detect the default reset on the DIP
switches and display out the status, also the management module can
control the function through the chassis system.
NOTE: To control the function in a working station, need to collocate together with optional Chassis System
and Management Module.
LED Indicator
The LED indicators give you instant feedback on status of the converter:

Link Pass Through Function
LLCF (Link Loss Carry Forward)
When a device connected to the converter and the TP line loss the link,
the converter’s fiber 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.
There is a default LLCF setting on this converter.

LLR (Link Loss Return)
When a device connected to the converter and the fiber line loss the link,
the converter’s fiber will disconnect the link of transmit.
There is a switch to enable or disable the function of the media
converter.

NOTE: If connecting two converters with LLR function in both end, it is recommended that the monitor end
converter had to turn off the LLR function, and turn on the LLR function of the remote end converter.
