1. Overview
Antaira’s LNX-0702C-SFP series industrial gigabit unmanaged Ethernet switch series is IP30
rated and DIN-Rail mountable. The unit is designed with five 10/100Tx Ethernet ports and two
dual rate (100/1000) SFP slots, making it ideal for applications that demand high bandwidth and
long distance communication.
This product series provides a 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-0702G-SFP series includes two models: one with an 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 special needs within 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.
LED Color Description

2.5 Ethernet Ports

RJ-45 Ports
RJ-45 Ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for 10Base-T, or 100Base-Tx
device 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 on the
next page for the 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 networking connections to PCs, servers, other
switches or hubs. With a 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, MDI and MDI-X port pin outs.
Pin MDI-X Signal Name MDI Signal Name
1 Receive Data Plus (RD+) Transmit Data Plus (TD+)
2 Receive Data Minus (RD-) Transmit Data Minus (TD-)
3 Transmit Data Plus (TD+) Receive Data Plus (RD+)
6 Transmit Data Minus (TD-) Receive Data Minus (RD-)
The following figures show the cabling schematics for straight-through and crossover.
