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-1802G-SFP series is an 18-port industrial Gigabit PoE+ managed
Ethernet switch embedded with 16*10/100/1000Tx Ethernet ports and 2*100/1000 dual rate SFP
slots for fiber connections. The LMX-1802G-SFP series is a fully manageable 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-1802G-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, 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.

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 pinouts.

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.
2.8 Wiring the Power Inputs
Please follow the steps below when inserting the power wire.
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 Figure2.6.
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.

Note:
Only use copper conductors, 60/75 ° C , tighten to 5lbs.
• The wire gauge for the terminal block should range between 18~20AWG .
Caution:
• The wire gauge for the terminal block should range between 12 ~24AWG
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 blow in Figure 2.15.
Figure 2.15 - Grounding screw
Caution: Using a shielded cable achieves better electromagnetic compatibility.

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 user
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.
