1.4 Special Functions
AutoMDI/MDI-XFunction
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.
Auto-negotiationFunction
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.
FarEndFaultFunction
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.

-11-
LinkFaultPassThroughFunction
When this function is enabled, a link fault detected on the TP port will
forcealinkdownontheFXport.Similarly, a link fault detectedontheFX
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.

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
Ifanyitemisfound missing or damaged, please contact yourlocalreseller
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 in KC-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
ACpower adapterwhichis usedtosupplytheDC powerfortheunitshould
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 theDC cable with
the cable tie located the back of the converter.
3. Connect the power adapter to the AC outlet.
4.CheckPower LED indication.

Since the WDM single fiber media converters use different wavelengths
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.

3. Optional Configuration Settings
The media converter provides additional configuration settings which
are user-inaccessible. The settings are built on the board inside the prod-
uct case. The settings are provided for technical installers to adapt the
converter to fit some specific application needs.
3.1 User Inaccessible Jumpers
The setting jumpers are not accessible by users generally. For accessing
these jumpers, the upper case must be removed from the product. Re-
moving the case must be performed by an authorized and experienced
technical person. The setting jumper block is located on the position
shown below:
The setting functions are as follows:
JP1 Forwarding mode setting Open - Store-and-forward mode
Short -Smart-forwardmode
JP2 802.3x function setting Open -Enable
Short - Disable
JP3 FX port duplex setting Open -Full duplexmode
Short -Half duplex mode

-18-
3.1.1 Forwarding Mode Setting JP1
The following table lists the forward method used in different TP to FX
conversions:
JP1 Setting TPportto/fromFXport Forwardmethod
Store-and-forward 10BASE-Tto100BASE-FX Store and forward
100BASE-TXto100BASE-FX Store and forward
Smart-forward 10BASE-Tto100BASE-FX Store and forward
100BASE-TXto100BASE-FX Direct conversion
On smart-forward mode, the converter can change to direct conversion
automatically when it detects same speed on both TP port and FX port.
Direct conversion method converts the signal between TP port and FX
port without storing the received packet on one port then forwarding to
another port. The media converter operates with the minimum latency.
Note:
1. In direct conversion, be sure both devices connected to the TP port
and FX port have same duplex mode for proper transmission.
2. In direct conversion, 802.3x function is disabled and the media
converter will not generate pause frame, but just forwards the
received pause frame directly from one port to another port.
3. In direct conversion, the media converter is not limited to the
maximal length of the receiving packets.

-19-
3.1.2 802.3x Function Setting JP2
IEEE 802.3x function is the flow control method used for full duplex op-
eration on TP port and FX port under store and forward mode. This
method uses pause frames for one port to stop further transmission from
its link partner.
3.1.3 FX Duplex Setting JP3
This setting is used to set the duplex mode of the FX port.
3.2 JP1-JP3 Factory Default Settings
The factory default settings for JP1, JP2, and JP3 are as follows:
JP1 Open Store-and-forward mode
JP2 Open 802.3x function is enabled
JP3 Open FXportfullduplex
