Overview
This series is rated IP30 and installation by DIN Rail. Each unit of this industrial gigabit unmanaged
Ethernet switch series has 10*10/100/1000Tx and 2 dual rate (100/1000) SFP slots, suitable for
applications that require high bandwidth and long distance communication.
In order to prevent unregulated voltage, this series provides high EFT and ESD protection. This
also allows it to function in harsh environments, as well as support power redundancy with a dual
power input design with reverse polarity protection. The built-in relay warning function alerts
users about occurring power failures.
With one model having an operating temperature of -10°C ~ 65°C , and another with a wide
operating temperature of -40°C ~ 75°C, this series is designed to meet any needs for industrial
automation application and harsh environments.

Ethernet Ports
RJ-45 Ports (Auto MDI/MDIX)
The RJ-45 ports are auto-sensing for 10Base-T, 100Base-TX or
1000Base-T devices connections. Auto MDI/MDIX means that the
switch can connect to another switch or workstation without
changing the straight-through or crossover cabling. See the figures
as below for straight-through and crossover cabling schematics.

Cabling
Use the four twisted-pair, category 5e, or the above cabling for RJ-45 port connections. The cable
between the switch and the link partner (switch, hub, workstation, etc.) must be less than 100
meters (328 ft.) long.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
communications for both telecommunication and data communication applications.
To connect the transceiver and LC cable, please follow below steps:
Step 1. Insert the SFP transceiver module into the SFP slot as shown below in Figure 2.9. Notice
that the triangle mark is at the bottom of the SFP slot. Figure 2.10 shows SFP transceiver
module was inserted.
Figure 2.9: Transceiver to the SFP Module
Figure 2.10: Transceiver Inserted

8
Step 2. Insert the fiber cable of the LC connector into the transceiver as shown below in Figure
2.11.
Figure 2.11: LC Connector to the Transceiver
To remove the LC connector from the transceiver, please follow the steps shown below:
Step 1. Press the upper side of the LC connector from the transceiver and pull it out to release as
shown below in Figure 2.12
Figure 2.12: Remove LC Connector

9
Step 2. Push down the metal clasp and pull the transceiver out by the plastic part as shown
below in Figure 2.13
Figure 2.13: Pull Out from the SFP Module
Wiring the Power Inputs
Please follow the below steps to insert the power wire.
Step 1. Insert the positive and negative wires into the PWR1 (V1+, V1-) and PWR2 (V2+, V2-)
contacts on the terminal block connector as shown below in Figure 2.14.
Figure 2.14: Power Terminal Block
Step 2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in
Figure 2.15.
Figure 2.15: Power Terminal Block
Note:
Only use copper conductors, 60/75°C, tighten to 5 lbs.
The wire gauge for the terminal block should range between 18~20 AWG.

10
Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of the terminal block connector as the picture shows
below in Figure 2.16. By inserting the wires, it will detect the fault status including power failure
or port link failure (managed industrial switch only) and form a normally open circuit. An
application example for the fault alarm contact is shown below in Figure 2.16.
Figure 2.16: Wiring the Fault Alarm Contact
Note:
The wire gauge for the terminal block should range between 12 ~ 24 AWG.
If only using one power source, jumper Pin 1 to Pin 5 and Pin 2 to Pin 6 to eliminate
power fault alarm.

Mounting Installation
DIN-Rail Mounting
The DIN-Rail is pre-installed on the industrial Ethernet switch from the factory. If the DIN-Rail is
not on the industrial Ethernet switch, please see Figure 3.1 to learn how to install the DIN-Rail on
the switch.
Figure 3.1: The Rear Side of the Switch and DIN-Rail Bracket
Follow the steps below to learn how to hang the industrial Ethernet switch.
Step 1. Use the screws to install the DIN-Rail bracket on the rear side of the industrial Ethernet
switch.
Step 2. To remove the DIN-Rail bracket, do the opposite from Step 1.
Step 3. After the DIN-Rail bracket is installed on the rear side of the switch, insert the top of the
DIN-Rail on to the track as shown below in Figure 3.2.

12
Figure 3.2: Insert the Switch on the DIN-Rail
Step 4. Lightly pull down the bracket on to the rail as shown below in Figure 3.3.
Figure 3.3: Stable the Switch on DIN-Rail
Step 5. Check if the bracket is mounted tightly on the rail.
Step 6. To remove the industrial Ethernet switch from the rail, do the opposite from the above
steps.

13
Wall Mounting
Follow the steps below to mount the industrial Ethernet switch using the wall mounting bracket
as shown below in Figure 3.4.
Step 1. Remove the DIN-Rail bracket from the industrial Ethernet switch by loosening the screws.
Step 2. Place the wall mounting brackets on the top and bottom of the industrial Ethernet switch.
Step 3. Use the screws to screw the wall mounting bracket on the industrial Ethernet switch.
Step 4. Use the hook holes at the corners of the wall mounting bracket to hang the industrial
Ethernet switch on the wall.
Step 5. To remove the wall mount bracket, do the opposite from the steps above.

Hardware Installation
Installation Steps
This section will explain how to install EG2-1202-SFP series.
Installation Steps
Step 1. Unpack the industrial Ethernet switch from the original packing box.
Step 2. Check if the DIN-Rail bracket is screwed on the industrial Ethernet switch.
If the DIN-Rail is not screwed on the industrial Ethernet switch, please refer to the DIN-Rail
Mounting section for DIN-Rail installation.
If you want to wall mount the industrial Ethernet switch, please refer to the Wall Mounting
section for wall mounting installation.
Step 3. To hang the industrial Ethernet switch on a DIN-Rail or wall, please refer to the Mounting
Installation section.
Step 4. Power on the industrial Ethernet switch and then the power LED light will turn on.
If you need help on how to wire power, please refer to the Wiring the Power Inputs section.
Please refer to the LED Indicators section for LED light indication.
Step 5. Prepare the twisted-pair, straight-through category 5 cable for Ethernet connection.
Step 6. Insert one side of the RJ-45 cable into switch’s Ethernet port and on the other side into
the networking device’s Ethernet port, e.g. switch PC or server. The Ethernet port’s (RJ-45)
LED on the industrial Ethernet switch will turn on when the cable is connected to the
networking device.
Please refer to the LED Indicators section for LED light indication.
Step 7. When all connections are set and the LED lights all show normal, the installation is
complete.

Trouble Shooting
●Verify you have the right power cord or adapter. Never use a power supply or adapter with a
non-compliant DC output voltage or it will burn the equipment.
●Select the proper UTP or STP cable in order to construct the network. Use an unshielded
twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections: 100Ω Category 5e
for 10M/100/1000Mbps. Also be sure that the length of any twisted-pair connection does not
exceed 100 meters (328 feet).
●Diagnosing LED Indicators: To assist in identifying problems, the switch can be easily monitored
with the LED indicators which help to identity if any problems exist.
◆Please refer to the LED Indicators section for LED light indication.
●If the power indicator LED does not turn on when the power cord is plugged in, the user may
have a problem with the power cord. Check for loose power connections, power losses or
surges at the power outlet.
◆Please contact Leonton for technical support service, if the problem still cannot be
resolved.
●If the industrial switch LED indicators are normal and the connected cables are correct but the
packets still cannot transmit, please check the system’s Ethernet devices’ configuration or
status.
