2.1 Unpacking
The product package contains:
z The media converter unit
z One AC power adapter
z One product CD-ROM
2.2 Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire and damage to the product, observe the following
precautions.
z Do not service any product except as explained in your system documentation.
z Opening or removing covers may expose you to electrical shock.
z Only a trained service technician should service components inside these compartments.
z If any of the following conditions occur, unplug the product from the electrical outlet and replace the part
or contact your trained service provider:
- The power cable, extension cable, or plug is damaged.
- An object has fallen into the product.
- The product has been exposed to water.
- The product has been dropped or damaged.
- The product does not operate correctly when you follow the operating instructions.
z Do not push any objects into the openings of your system. Doing so can cause fire or electric shock by
shorting out interior components.
z Operate the product only from the type of external power source indicated on the electrical ratings label. If
you are not sure of the type of power source required, consult your service provider or local power
company.

2.3 Mounting the Device
Desktop Mounting
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.
Wall Mounting
To mount the device on a wall, one wall mounting hole is provided on the bottom of the device. Hang the
device on the wall reliably. The following figure illustrates example of a device bottom face:

Optional Din-Rail Mounting
To mount the media converter on a Din-Rail, one optional Din-Rail mounting bracket is required. Screw the
bracket onto the bottom of the device with M3x0.5 screws as follows:

2.4 Applying Power with Power Adapter
The device provides a DC power jack for receiving DC power input from an external AC-DC power adapter.
One power adapter is packed in each product package. Consult your purchasing agency for the right part
number which matching the operating rating you require.
Note: Before you begin the installation, check the AC voltage of your area. The AC-DC power adapter should
have the AC voltage matching the commercial power voltage in your area.
3. Making LAN Connections
3.1 Making UTP Connections
The copper ports support 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 / 4-pair UTP Cat. 5, 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 connected, the port can sense the receiving pair automatically and configure self 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 switch will sense the speed and use half duplex for the
connection.

3.2 Making FX Port Connection
FX port operates on 100Mbps and full duplex. The following figures illustrate a connection example between
two fiber ports:
Duplex Connection
Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.
Bi-Di Connection (Bi-Directional)
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 converter to report a fiber link fault even when a
link failure occurred on transmitting fiber cable.
