RJ45 pins as following:
4.4 Ethernet
This multiplexer can offer 2 channels for 10/100M ,full/duplex auto-negotiation
LAN interface, support VLAN protocol, this interface can continuous learn MAC
addresses in the LAN that connected with it, and send the address as frame in another
LAN. Transparence to TCP/IP protocol, offers security connection between different
equipments in the network, used widely in network connection and monitor between
WAN and LAN.

4.6 Hot line phone
Please connect to telephone set. For point-to-point application, when off-
hook at any side, the other one will ring. Then the user at the other side should
also off-hook to answer.
4.9 Power supply
Dual power supply: AC220V and DC-48V：
AC220V socket: input voltage range AC 100V～260V；Please insert
power wire as the attachment;
DC-48V socket: input voltage DC-36V ~-72V. If the power of DC-48V is
used, the positive and negative terminal can be optional because there is the
self-test circuit for the polarity inside the optical multiplexer.
Normal Connect way
“FG” connect earth；
“-48V” connect the power negative；
“+48V” connect the power positive；

5 Installation
5.1 Equipment installation
After unpacking and before installation, make sure checking the following:
Make sure the package is well. If the package is damaged, contact
service office quickly for solution.
Check the package according to the product list, if find equipment severe
damaged or lack of some components, please contact installation worker or
service office of us.
Check whether the equipment type meets with the type you ordered.
Check whether the component is in integrity.
Check the power supply type.
5.1.1 Quick installation
Fasten the Equipment in 19 inch rack with the screws in the equipment
package.
Use reliable ground connection at GND point of the equipment
Use power tab to connect power according to the manual, don’t
exchange the polarities.
Create user equipment connecting wire according to your demand (2M,
V.35 and 10 Base-T), then connected, don’t exchange receive and
transfer wires.
Connect receive and transfer optical with optical receive and transfer
port of the equipment. Don’t exchange receiving and transmitting wire,
make sure the optical fiber head is clean, insert optical jumper, make
sure connection well. (fiber bending radius≥50 mm)
Use multimeter to test power polarity and voltage, make sure it
matches with equipment requirement.
After complete installation and make sure it’s ok, power on the switch.
Check indicator light meet with practice situation (see related part of

16E1+4ETH Optical Multiplexer
14
manual).
A clean, steady environment and firm installation should be provided
for desktop or wall hanging equipment.
5.1.2 Cautions about installation
Avoid severe liberation and mechanical damage during the process of
delivering and installation.
Arrange fiber appropriately, fiber bending radius≥50 mm.
Check voltage and polarity meet with back panel, or it will cause
permanent damage to the equipment.
Fiber connector can’t be contaminated, wipe optical fiber head slightly
using alcohol, or it will affect transmission. If the fiber connector not
butt joint well, it may be cause power decline, adjust fiber connector
according to practical situation.
The installation location should be convenient for personal passing and
equipment movement.
The environment should be dry, clean and ventilated well.
Essential static-protective is needed during the installation and
maintenance, ground the chassis to increase anti-interference
capability and prevent lightning strike. Before use the equipment,
independence work ground and protect ground should provided, make
sure it ground well.
