LMX-1202G-SFP Series - Hardware Manual - v2.0
1 Overview
Antaira Technologies’ LMX-1202G-SFP series is a 12-port industrial managed Ethernet switch that is
embedded with 10*10/100/1000Tx Ethernet ports and 2*100/1000 SFP slots. The LMX-1202G-SFP series
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-1202G-SFP 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 70°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 within transportation, ITS and any other outdoor or harsh environment.

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.

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 

Antaira Technologies - Industrial Ethernet Switch
LMX-1202G-SFP Series - Hardware Manual - v2.0
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.

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 2.9  .
