1.4 Special Functions
1.4.1Auto MDI/MDI-X Function
This function allows the TP 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.
1.4.2 Auto-negotiation Function
When TP port is set on Auto-negotiation mode (SW1:ON), it is featured
with auto-negotiation function and full capability. It performs a negotia-
tion process for the speed and duplex configuration with the connected
device automatically when each time a link is being established.
1.4.3 Far End Fault Function
The FX port is facilitated with this function, which conforms to IEEE
802.3u 100BASE-FX specifications. When the FX port detects a link
failure on its receiving circuitry, it will send out an FEFI (Far End Fault
Indication) signal to the remote connected device to indicate a remote
fault is detected. It also is capable to receive FEFI signal sent from the
remote link partner. Upon receiving an FEFI signal, it indicates a link
failure occurred on the transmitting path. This function allows the con-
verter to report a fiber link fault even when a link failure occurred on
transmitting fiber cable.

-12-
1.4.4 Link Fault Pass Through Function
When this function is enabled, a link fault detected on the TP port will
forcealinkdownontheFXport.Similarly, a link fault detected on the FX
port will also force a link down on the TP port. As illustrated in the
following figure, this function allows to pass TP link fault to the remote
link partner and makes the converter like aTPcable extender.

-13-
1.4.5 Remote TP Port Monitoring Function
The converter provides LEDindicators labeled RTPLINK/100M/FDX to
display the TP port status of its remote link partner on FX port. As
illustrated in the following figure, the remote MC must be enabled for
periodical status report.
1.4.6 Loop Back Test Function
As illustrated in the following figure, the local MC starts a loop back test
by pressing the loop back test button. It sends test frames from its FX
port to the remote MC. The remote MC forwards the received test frames
back to local MC from its FX port. The local MC verifies the loop back
test frames and display the test result on RTP LINK/100M/FDX LEDs.
This function can help installer to check the full path from a local MC
through fiber to a connected remote MC and back to local MC.

2. Installation
2.1 Unpacking
Check that the following components have been included:
• Installation guide (or contained in the product CD)
• 10/100MediaConverter
• OneAC power adapter
Ifanyitemisfoundmissingordamaged, please contact your local reseller
forreplacement.
2.2 Mounting the Device
DesktopMounting
The media converter can be mounted on a desktop or shelf. Make sure
that there is proper heat dissipation from and adequate ventilation around
the device. Do not place heavy objects on the device.
WallMounting
The media converter also can be mounted on a wall. On bottom of the
device, wall mounting hole is provided for wall mounting.
InstallationintoCenterChassisKC-1300
Themedia converter also can be installed inKC-1300 center chassis.The
center chassis provides the power supply to the converter. 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.

2.3 Applying Power
Before you begin the installation, check the AC voltage of your area. The
ACpoweradapterwhichisusedtosupply theDCpower fortheunit should
have the AC voltage matching the commercial power voltage in your area.
TheACPowerAdapterSpecifications
AC input power: AC power voltage of your area, options -
RatedAC120V/60HzDC7.5V1A
RatedAC230V/50HzDC7.5V1A
RatedAC100V/50-60HzDC7.5V1A
RatedAC100V/50-60HzDC5V1A
RatedAC240V/50HzDC7.5V1A
Steps to apply the power to the converters are:
1. Connect power adapter DC plug to the DC input jack located on the
back of the converter before connecting to the AC outlet.
2. To ensure against accidental disconnection, tie the DC cable with
the cable tie located the back of the converter.
3. Connect the power adapter to the AC outlet.
4.CheckPowerLED indication.

for transmission and receiving respectively, the link partner device lo-
cated on the remote end of the single fiber should match the wavelength
used on the single fiber converter.

2.7 Performing Loop Back Test
To perform a loop back test between a local MC and a remote MC con-
nected by a fiber cable, the steps are:
1. Push and press Loop back test button of local MC.
2. Check RTPLINK LED. It blinks to indicate the MC is in loop back
test mode.
3. Check RTP100M LED. It is ON to indicate a complete of loop back
test and OFF during test.
4. Check RTPFDX LEDfor the test result. It is ONto indicate aTEST
PASS and OFF forTEST FAIL.
5. Release Loop back test button. RTPLINK/100M/FDX LEDs are back
to display remote TP port status.
