1. Introduction
All Antaira industrial managed switches come with a pre-installed “user-friendly” web console
interface, which allows users to easily configure and manage the units, whether one is using a serial
console and Command Line Interface (CLI) commands like Telnet, SSH, HTTP (Web GUI) or Simple
Network Management Protocols (SNMP).
1.1 Product Overview
Antaira Technologies’ LMX-0702G-SFP-V2 series is a 7-port industrial Gigabit managed Ethernet
switch embedded with 5*10/100/1000Tx Ethernet ports and 2*100/1000 SFP slots. The LMX-0702G-
SFP-V2 is a fully manageable Light Layer 3 Ethernet switch that is pre-loaded with a user-friendly
web management console design. It supports the ring network redundancy function using the
market’s open standard ITU-T G.8032 ERPS (Ethernet Ring Protection Switch) protocol that has a
<50ms network recovery time. The advanced network filtering and security functions, such as IGMP,
VLAN, QoS, SNMP, RMON, Modbus TCP, and 802.1X/HTTPS/SSH/SSL increase determinism and
improve network management for remote SCADA systems or control networks.
The LMX-0702G-SFP-V2 series is IP30 rated and DIN-rail mountable. There are also two wide
operating temperature models for either a standard temperature range (STD: -10°C to 65°C) or an
extended temperature range (EOT: -40°C to 75°C). It also provides high EFT and ESD protection for
industrial networking applications, such as power/utility, water wastewater, oil/gas/mining, factory
automation, security surveillance, ITS and any other outdoor or harsh environment.

• RJ-45 Ports
RJ-45 Ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for 10Base-T, 100Base-TX, or
1000Base-T 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.

Table 2.3 - RJ45 Pin Assignments
Note: The “+” and “-”signs represent the polarity of the wires that make up each wire pair.
All ports on this industrial Ethernet switch support automatic MDI operations. Users can use
straight-through cables (see figure below) for all network connections to PCs, servers, and other
switches or hubs. With straight-through cabling, pins 1, 2, 3, and 6 are at one end of the cable
and are connected straight through to pins 1, 2, 3 and 6 at the other end of the cable. The table
below (Table 2.4) shows the 10BASE-T/100BASE-TX/1000BASE-T MDI port pin outs.

2.7 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the 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.) 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.
2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in
Figure 2.7.
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.
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 2.15.
Figure 2.15 - Grounding screw symbol
Caution: Using a shielded cable achieves better electromagnetic compatibility.
Attention: L'utilisation d'un câble blindé permet une meilleure compatibilité électromagnétique.
