OVERVIEW
This series is rated IP30 and installation by DIN Rail. Each unit of this industrial gigabit unmanaged
Ethernet switch series has 8*10/100/1000Tx RJ45 copper ports and 4 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.

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.
Caution:
Please employ optional optical transceiver (SFP/Fixed Fiber) that complies with IEC 60825-1, 21
CFR 1040 Section 1040.10 and 1040.11, classified as Class 1 laser product.
Attention:
Veuillez utiliser un émetteur-récepteur optique en option (SFP/fibre fixe) conforme à la norme IEC
60825-1, 21 CFR 1040 Section 1040.10 et 1040.11, classé comme produit laser de classe 1.
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 2.4. Notice that the
triangle mark is at the bottom of the SFP slot. Figure 2.5 shows SFP transceiver module was
inserted.
Figure 2.4: Transceiver to the SFP Module
Figure 2.5: Transceiver Inserted
Step 2 Insert the fiber cable of the LC connector into the transceiver as shown below in Figure 2.6.
Figure 2.6: LC Connector to the Transceiver

8
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 2.7
Figure 2.7: Remove LC Connector
Step 2 Push down the metal clasp and pull the transceiver out by the plastic part as shown below in
Figure 2.8
Figure 2.8: Pull Out from the SFP Module

Wiring the Power Inputs
Caution: Please follow the below steps to insert the power wire.
Attention: Veuillez suivre les étapes ci-dessous pour insérer le câble d'alimentation.
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 2.9.
Figure 2.9: Power Terminal Block
Step 2 Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in Figure 2.10.
Figure 2.10: Power Terminal Block
Caution: Only use copper conductors, 125°C, tighten to 7 in-lbs (0.79 Nm). The wire
gauge for the terminal block should range between 18~20 AWG.
Attention: Utilisez uniquement des conducteurs en cuivre, 125 ° C, serrer à 7 in-lbs
(0,79 Nm). Le calibre des fils du bornier doit être compris entre 18 et 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 2.11. 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 2.11.
Grounding Note
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run
the ground connection from the ground screw to the grounding surface prior to connecting devices. The
grounding screw symbol is shown blow in Figure 2.5.
Figure 2.5: Grounding screw symbol
Caution: Using a shielded cable achieves better electromagnetic compatibility.
Attention: L'utilisation d'un câble blindé permet une meilleure compatibilité
électromagnétique.

HARDWARE INSTALLATION
Installation Steps
This section will explain how to install EG2-1204-SFP series.
Installation Steps
Step 1. Unpack the industrial Switch from the original packing box.
Step 2. Check if the DIN-Rail bracket is screwed on the industrial Switch.
•If the DIN-Rail is not screwed on the industrial Switch, please refer to the DIN-Rail Mounting section
for DIN-Rail installation.
•If you want to wall mount the industrial Switch, please refer to the Wall Mounting section for wall
mounting installation.
Step 3. To hang the industrial Switch on a DIN-Rail or wall, please refer to the Mounting Installation section.
Step 4. Power on the industrial 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

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.
●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.
