1.3 Special Functions
AutoMDI/MDI-XFunction
This function allows the copper port to auto-detect the twisted-pair sig-
nals and adapts itself to form a valid MDI to MDI-X connection with the
remote connected device automatically.
Link Fault Pass Through Function
When a link fault is detected on the copper port, the device will force a
link down on the fiber port immediately. Similarly, a link fault detected on
the fiber port will also force a link down on the copper port. As illustrated
in the following figure, this function allows to pass copper link fault to
the remote link partner and makes the converter like a twisted pair cable
extender.

Far End Fault Function
The fiber port is facilitated with this function. When the fiber 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
if the link partner detected a receiving fault. 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.

2.2 Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire, and damage to
the equipment, observe the following precautions.
• Do not service any product except as explained in your system
documentation.
• Opening or removing covers may expose you to electrical shock.
Only a trained service technician should service components inside
these compartments.
• 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.
• Do not push any objects into the openings of your system. Doing
so can cause fire or electric shock by shorting out interior compo-
nents.
• 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.

mounting the converter in a industrial DIN-rail enclosure.
The steps to mount the device onto a DIN rail are:
1. Install the mounting bracket onto the device unit as shown below:
2. Attach bracket to the lower edge of the DIN rail and push the unit
upward a little bit until the bracket can clamp on the upper edge of
the DIN rail.
3. Clamp the unit to the DIN rail and make sure it is mounted securely.
4. Make sure that there are proper heat dissipation from and adequate
ventilation around the device.

2.5 Applying Power
The power specifications of the device are:
Operating Voltage
+7~+30VDC
Power Consumption Max. 2.5W@30VDC
The device provides two types of power interfaces, terminal block and DC
power jack for receivingDC power input from external power supply.
Using Terminal Blocks
Either DC1 interface or DC2 interface can be used to receive DC power
from an external power system. Or, DC2 also can be used to deliver the
power received on DC1 to next device in cascading way.

Three 2P terminal plugs are provided together with the device. Two of the
three plugs are used forDC1 andDC2 interfaces respectively. The plug is
shown below:

Power wires: 24 ~ 12AWG(IEC 0.5~2.5mm2)
Install the power source wires with the plug properly. Screw the wire with
plug securely. Then, plug in DC1 contacts.
If cascading the power to next device is needed, install the power wires
and plug for another switch. Then, use DC2 contacts.
Note: Only up to four device units can be cascaded to receive power
from one main power input source.

2.8 Making Fiber Port Connection
The mini-GBIC (SFP) port must be installed with an SFP fiber trans-
ceiver for making fiber connection. The device may come with an SFP
transceiver pre-installed when it is shipped from factory.
Installing SFPFiberTransceiver
Turn off the power to the device. 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. Until the SFP transceiver is seated
securely in the slot, place the bail in lock position.
Connecting Fiber Cables
LC connectors are commonly equipped on most SFP transceiver mod-
ules. 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.
Note: For Bi-Di (Bidirectional) SFP transceivers which use two differ-
ent wavelengths for TX and RX respectively over single fiber
cable, only one connector is provided on the fiber port and only
one fiber cable is used.
Network Cables
Multimode (MMF) - 50/125, 62.5/125
Singlemode(SMF)-9/125
