Antaira Technologies - Industrial Ethernet Switches
LNX-800A-E Series - Hardware Manual - v1.0
1 Overview
Antaira Technologies’ LNX-800A-E series is a smart 8-port industrial unmanaged Ethernet switch embedded with
8*10/100Tx Ethernet ports. The RJ45 interface can also be auto-detected, so MDI or MDI-X is automatically selected and
a crossover cable is not required. All Ethernet ports have memory buffers that support the store-and-forward mechanism.
This assures that data is properly transmitted.
The LNX-800A-E series supports 12~48VDC dual power inputs, and also offers two wide operating temperature models
for either a standard temperature range (STD: -10°C to 70°C) or an extended temperature range (EOT: -40°C to 75°C). It
supports IEEE 802.3/802.3u/802.3ab/802.3x with 10/100Tx for full or half duplex data transmission.
In addition, the built-in Network Broadcast Storm Protection and built-in relay warning function will alert network engineers
whenever there is a power failure or port break. With an increasing demand for E-Mark certified products not only for the
EU but also the Middle East and African markets, this product is a perfect solution for easy network deployment in various
vehicular environments.

2.5 Ethernet Ports
●RJ45 Ports
RJ45 Ports (Auto MDI/MDI-X): The RJ45 ports are auto-sensing for 10Base-T, 100Base-TX connections. Auto MDI means
that the switch can connect to another switch or workstation without changing the straight-through or crossover cabling.
See the figures below for straight-through and crossover cabling schematics.

Note: “+” and “-” signs represent the polarity of the wires that make up each wire pair.
2.6 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.
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.

Antaira Technologies - Industrial Ethernet Switches
LNX-800A-E Series - Hardware Manual - v1.0
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 Fault Alarm Contact
The fault alarm contact is in the middle of the terminal block connector as the picture shows below in Figure 2.8. By
inserting the wires, it will detect the fault status including power failure or port link failure (managed industrial switch
only), and form a normal open circuit. An example is shown below in Figure 2.8.
Figure 2.8 - Wiring the Fault Alarm Contact

Antaira Technologies - Industrial Ethernet Switches
LNX-800A-E Series - Hardware Manual - v1.0
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

4.2 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.
