Overview
This series is rated IP30 and installation by DIN Rail. Each unit of this industrial unmanaged Ethernet
switch series has 5*10/100Tx Ethernet ports, which the RJ-45 interface provides auto detection of
MDI or MDI-X.
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.
With one model having an operating temperature of -10 ~ 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.
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 2.4.
Figure 2.4: Power Terminal Block
Step 2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in
Figure 2.5.
Figure 2.5: 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.

13
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 2.7.
Figure 2.7: 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 CET2-0500 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.
