1. Overview
Antaira Technologies’ LNX-1204G-SFP industrial gigabit unmanaged Ethernet switch series is
IP30 rated and DIN-Rail mountable. Each unit is designed with eight gigabit Ethernet ports and
four dual rate (100/1000) SFP slots, making it ideal for applications that demand high bandwidth
port expansion and long distance communication.
This product series provides high EFT and ESD protection to prevent any unregulated voltage
and is suitable for harsh environments. It supports the power redundancy feature using a dual
power input design with reverse polarity protection. In addition, the built-in relay warning function
alerts maintainers when power failures occur.
The LNX-1204G-SFP series includes two models: one with standard operating temperature range
of -10 to 70°C, and the other one with an extended operating temperature range of -40 to 75°C. It
is a perfectly designed product to fulfill any special needs for industrial automation, outdoor
applications and harsh weather environments.

2.4 LED Indicators
There are LED light indicators located on the front panel of the industrial Ethernet switch that
display the power status and network status. Each LED indicator has a different color and has
its own specific meaning, see below in Table 2.1.
2.5 Ethernet Ports
 RJ-45 Ports
RJ-45 Ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for 10Base-T, 100Base-TX or
1000Base-T devices connections. Auto MDI/MDIX means that the switch can connect to another
switch or workstation without changing the straight-through or crossover cabling. See the figures
shown below for straight-through and crossover cabling schematics.

All ports on this industrial Ethernet switch support automatic MDI/MDI-X operation. Users can
use straight-through cables (see figure below) for all network connections to PCs, servers, other
switches or hubs. With straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are
connected straight through to pins 1, 2, 3 and 6 at the other end of the cable. The table below
(Table 2.3) shows the 10BASE-T, 100BASE-TX, 1000BASE-TX MDI and MDI-X port pin outs.
The following figures show the cabling schematics for straight-through and crossover.
