1.3 Special Functions

Auto MDI/MDI-X Function

This function allows the copper 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 .

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 . Si milarly , 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.

-11-

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.

2.5 Applying Power

The power specifications of the device are:

Operating V oltage +7 ~ +30VDC
Power Consumption Max. 2.5W @30VDC

The device provides two types of power interfaces, terminal block and DC
power jack for receiving DC power input from external power supply .

Using T erminal 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 ca scading way .

DC1 + Vdc Positive (+) terminal
DC1 - Vdc Negative (-) terminal
DC2 + Vdc Positive (+) terminal
DC2 - Vdc Negative (-) terminal

Three 2P terminal plugs are provided together with the device. T wo of the
three plugs are used for DC1 a nd DC2 interface s respectively . The plug is
shown below:

-19-

Power wires: 24 ~ 12A W G (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.

-20-

Using DC Power Jack

DC Jack Connector: Jack D 6.3mm D 2.0mm
AC Power Adapters: Optional commercial rated adapters are available

for purchasing.

Rated AC120V/60Hz DC7.5V 1A
Rated AC230V/50Hz DC7.5V 1A
Rated AC100V/50-60Hz DC7.5V 1A
Rated AC240V/50Hz DC7.5V 1A

Connect power adapter DC plug to the DC power jack of the converter
before connecting to the AC outlet. Connect the power adapter to the
AC outlet.

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.

-21-

2.6 Power Failure Relay Output

The device provides a relay output to report power failure event to a
remote alarm monitoring system. The replay output is provided with two
contacts labeled PF+ and PF- in the terminal block interface.

Use the provided 2P terminal plug for signal wiring and plug into the PF+/

- contacts. The function is designed as :

Power is normal PF+ contact is shorted with PF- contact.
Power failure PF+ contact is disconnected with PF- contact.

Note: Be sure the voltage applied on PF+/- contacts is within the

specification of 30VDC/1A max. or 120VAC/0.5A max.

2.8 Making Fiber Port Connection

The mini-GBIC (SFP) port must be installed with an SFP fiber trans­ceiver for making fiber connection. The device may come with an SFP
tra nsce iver pre-installed when it is shipped from factory.

Installing SFP F iber Transceiver

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 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.

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
Single mode (SMF) - 9/125
