Leonton ET2-0800 8-Port Industrial Ethernet Switch
OVERVIEW
This series is rated IP30 and installation by DIN Rail. Each unit of this
industrial unmanaged Ethernet switch series has 8*10/100Tx Fast 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. 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 the 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.

Note: “+” and “-” signs represent the polarity of the wires that make up each wire pair.
Cabling
Use the two/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.
-
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.
-
Step 2 Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in Figure 2.5.
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.
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 2.7. 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 2.6.
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.
Caution: Using a shielded cable achieves better electromagnetic compatibility.
MOUNTING INSTALLATION
DIN-Rail Mounting

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.
-
Lightly pull down the bracket on to the rail as shown below in Figure 3.3.
-
Check if the bracket is mounted tightly on the rail.
-
To remove the industrial Ethernet switch from the rail, do the opposite from the above steps.
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.
Below, in Figure 3.5 are the dimensions of the wall mounting bracket.
HARDWARE INSTALLATION
Installation Steps
This section will explain how to install ET2-0800 series.
- 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 industrial 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.
Caution: If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
Caution: The installation that the safety to any system incorporating the
equipment is the responsibility of the assembler of the system.
Caution: If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
Caution: The installation that the safety to any system incorporating the
equipment is the responsibility of the assembler of the system.
Caution: This is an OPEN TYPE module and should be installed in a final
safety enclosure characteristic.
Caution: Ambient Relative Humidity should be within the range of 5 and
95% (noncondensing).
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/100Mbps. 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.
