Note: “+” and “-” signs represent the polarity of the wires that make up each wire pair.
2.7 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the RJ45 port connections. The cable between the switch
and the link partner (switch, hub, workstation, etc.) must be less than 100 meters (328 ft.) in length.
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 and
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 et classé comme produit laser de classe 1.
2.8 Wiring the Power Inputs
Caution: Please follow the steps below when inserting the power wire.
Attention: Veuillez suivre les étapes ci-dessous lors de l'insertion du câble d'alimentation.

Antaira Technologies - Industrial Ethernet Switches
LMX-2012G-SFP Series - Hardware Manual - v1.0
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 2.6.
Figure 2.6 - Power Terminal Block
2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in Figure 2.7.
Figure 2.7 - Power Terminal Block
Caution:
Only use copper conductors, 125°C, tighten to 5 lbs.
The wire gauge for the terminal block should range between 18~20 AWG.
Attention:
Utilisez uniquement des conducteurs en cuivre, 125°C, serrez à 5 lb.
Le calibre des fils du bornier doit être compris entre 18 et 20 AWG.
2.9 Wiring the Relay Contact
The relay contact is in one of the terminal block connectors as the picture shows below in Figure 2.8. By inserting the
wires, it will detect the fault status including power failure or DI Event, and port link failure (managed industrial switch
only) and form a normally open circuit.
9

Antaira Technologies - Industrial Ethernet Switches
LMX-2012G-SFP Series - Hardware Manual - v1.0
Figure 2.8 - Wiring the Relay Contact
Caution:
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.
Attention:
Le calibre des fils du bornier doit être compris entre 12 et 24 AWG.
Si vous n'utilisez qu'une seule source d'alimentation, connectez les broches 1 à 5 et les broches 2 à 6 pour
éliminer l'alarme de panne de courant.
2.10 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 below in Figure 2.9.
Figure 2.9 - Grounding Screw Symbol
Caution: Using a shielded cable achieves better electromagnetic compatibility.
Attention: L'utilisation d'un câble blindé permet une meilleure compatibilité électromagnétique

4 Hardware Installation
4.1 Installation Steps
This section will explain how to install the industrial Ethernet switch:
Caution: This device is intended for indoor use.
Attention: Cet appareil est destiné à une utilisation en intérieur.
Caution: The device is intended to be installed in an industrial control enclosure and panel.
Attention: L'appareil est destiné à être installé dans une armoire de commande et un panneau industriels.
Installation Steps
1. Unpack the industrial Ethernet switch from the original packing box.
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 it is required to wall mount the industrial Ethernet switch, please refer to the Wall Mounting section for wall
mounting installation.
3. To hang the industrial Ethernet switch on a DIN-Rail or wall, please refer to the Mounting Installation section.
4. Power on the industrial Ethernet switch and then the power LED light will turn on.
●For the 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.
5. Prepare the twisted-pair, straight-through category 5 cable for Ethernet connection.
6. Insert one side of the RJ45 cable into the 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 (RJ45) LED on the industrial Ethernet switch will turn on when the cable is connected to

4.2 Maintenance and Service
●If the device requires servicing of any kind, the user is required to disconnect and remove it from its mounting.
The initial installation should be done in a way that makes this as convenient as possible.
●Voltage / Power lines should be properly insulated as well as other cables. Be careful when handling them so as
to not trip over.
●Do not under any circumstance insert foreign objects of any kind into the heat dissipation holes located in the
different faces of the device. This may not only harm the internal layout, but might cause harm to users as well.
●Do not under any circumstance open the device for any reason. Please contact your dealer for any repair needed
or follow the instructions within the manual.
●Clean the device with dry soft cloth.
4.3 Troubleshooting
●Always verify the right power cord or adapter is being used. 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 RJ45 connections: 100Ω Category 5e for 10/100Mbps. 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 identify 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 Antaira 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.
