1. Introduction
The KGC-310M-C is Gigabit Ethernet media converter series which provide the following features:
Data Conversion between different Media types and Speed
The media converter supports the following conversions:
1000Mbps (1000BASE-T) copper to/from 1000Mbps (1000BASE-X) fiber
100Mbps (1000BASE-TX) copper to/from 1000Mbps (1000BASE-X) fiber
10Mbps (10BASE-T) copper to/from 1000Mbps (1000BASE-X) fiber
1000Mbps (1000BASE-T) copper to/from 100Mbps (100BASE-FX) fiber
100Mbps (1000BASE-TX) copper to/from 100Mbps (100BASE-FX) fiber
10Mbps (10BASE-T) copper to/from 100Mbps (100BASE-FX) fiber
Dual-speed Mini-GBIC (SFP) Fiber Connectivity
The mini-GBIC (SFP) port can be installed with different optional SFP optical fiber transceiver to
support multimode or single mode fiber for short reach up to long reach distance. The SFP can support
both 1000BASE-X and 100BASE-FX fiber connection. This feature extends a wider application range
with this device.
Loop-back Test Support
The media converter provides loop-back test function which can verify the fiber link with its link
partner by sending test packets to the link partner and verifying the echo packets sent back. This
feature is helpful in checking connection quality of fiber link during installation.
Link Fault Pass-Through
This feature can force the link to shut down as soon as it notices that the other link has failed. It allows
a link partner on one cable segment can notice a link fault occurred on the other segment and give
application a chance to react.

7
Remote TP Port Status Monitoring
When two devices are connected with each other via fiber link the device can monitor and display the
twisted-pair port status of the remote fiber link partner. The status display can be on the local LED
indicators or web management interface.
802.1Q Control
With software configuration support, the device is enhanced with more 802.1Q control features for
VLAN applications rather than just a typical media converter function. The optional features include:
Filtering all untagged packets
Filtering all tagged packets
Filtering tagged packets with certain VID
Egress un-tagging
Egress tagging
Double tagging
802.1ad Q-in-Q support
Web Management
The device is embedded with an Http server which provides management functions for advanced
network functions including Port Control and 802.1Q and 802.1ad functions. The management can be

KC-3DR can be purchased separately. The following figure shows an example after bracket
installation:
Center rack mounting
The media converter can also be installed in KC-1300 center chassis. The center chassis provides the
power supply to the converter also with optional power redundancy. Up to 16 units can be installed in
one chassis. Unscrew and remove the cover of the center connector before inserting the converter into
the chassis. Refer to the operation manual of center chassis KC-1300 for more information.

15
2.4 Applying Power
Before you begin the installation, check the AC voltage of your area. The AC power adapter which is
used to supply the DC power for the unit should have the AC voltage matching the commercial power
voltage in your area.
Steps to apply the power to the device are:
1. Connect power adapter DC plug to the DC input jack located on the back of the unit before
connecting to the AC outlet.
2. Connect the power adapter to the AC outlet.
3. Check Power LED indication.
Note: Before you begin the installation, check the AC voltage of your area. The AC power
adapter which is used to supply the DC power for the unit should have the AC voltage
matching the commercial power voltage in your area.

16
2.5 Making UTP Connections
The 10/100/1000 twisted-pair copper (TP) port supports the following connection types and distances:
Network Cables
10BASE-T: 2-pair UTP Cat. 3,4,5 , EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters
Auto MDI/MDI-X Function
This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid
MDI to MDI-X connection with the remote connected device automatically. No matter a straight
through cable or crossover cable is connected, the ports can sense the receiving pair automatically and
configure itself to match the rule for MDI to MDI-X connection. It simplifies the cable installation.
Auto-negotiation Function
The port is featured with auto-negotiation function and full capability to support connection to any
Ethernet devices. The port performs a negotiation process for the speed and duplex configuration with
the connected device automatically when each time a link is being established. If the connected device
is also auto-negotiation capable, both devices will come out the best configuration after negotiation
process. If the connected device is incapable in auto-negotiation, the port will sense the speed and use
half duplex for the connection.
Port Configuration Management
For making proper connection to an auto-negotiation INCAPABLE device, it is suggested to set port
configuration to one of non-auto (forced) operating modes and specify speed and duplex mode which
match the configuration used by the connected device.
Two methods for setting copper port configuration are as follows:
1. DIP SW (switches) SW1, SW2, SW3
2. Software management via web interface
Configuration -> Ports -> TP Mode

17
2.6 Making Fiber Connection
The mini-GBIC SFP (FX) port must be installed with an SFP fiber transceiver for making fiber
connection. Your device unit may come with an SFP transceiver pre-installed when it was shipped.
Installing SFP Fiber Transceiver
To install an SFP fiber transceiver into mini-GBIC SFP port, the steps are:
1. Turn off the power to the device unit.
2. Insert the SFP fiber transceiver into the mini-GBIC port. Normally, a bail is provided for every
SFP transceiver. Hold the bail and make insertion.
3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.
Dual Speed Support
The SFP port supports 1000BASE-X based SFP fiber transceivers and 100BASE-FX based SFP fiber
transceivers. Select “Auto”for port configuration. The system will detect the type of the installed
transceiver and configure the port properly and automatically during boot-up.
Connecting Fiber Cables
LC connectors are commonly equipped on most SFP transceiver modules. Identify TX and RX
connector before making cable connection. The following figure illustrates a connection example
between two fiber ports:
Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.
Network Cables
Multimode (MMF) - 50/125, 62.5/125
Single mode (SMF) - 9/125

18
2.7 Loop-back Test Push Button
The push button is used to perform loop-back test between two media converters connected with fiber
cable as shown below:
It allows installer to perform diagnostic to the fiber link during installation and check the test result
displayed on the LED indicators.
The button may also be used to restore the software configuration settings to factory default values.
