1. Overview
Antaira Technologies’ LNX-1202G-10G-SFP is a 12-port industrial grade gigabit Ethernet
unmanaged switch. This rugged switch is enclosed in a metal IP30 rated design with a full
gigabit high port count which allows for a more versatile implementation. The LNX-1202G-10G-
SFP series is equipped with 10*10/100/1000 Ethernet ports and 2*100/1000 SFP+ slots. This
unit is the perfect solution for any application requiring high bandwidth and long distance
communication.
The LNX-1202G-10G-SFP supports high EFT & ESD protection to prevent damage from
unregulated power coming into the unit. It has built-in redundant power inputs that support
reverse polarity and overload current protection. It supports DIN-rail as well as wall mountable
orientations and provides an operating temperature range of -40°C to 60°C. This is an industrial
grade unit made for any harsh or outdoor networking environment in factory automation, ITS,
power/utility, and water wastewater treatment plants. This device is also ideal for any other
application requiring a high port count solution.

2.5 Ethernet Ports
RJ45 Ports (Auto MDI/MDIX):
The RJ45 ports are auto-sensing for 10/100/1000Base-Tx 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.
Table 2.1

The following figures show the cabling schematics for straight-through and crossover cables.
The following figures show the 10,100, and 1000 Ethernet RJ‐45 pin outs.
2.6 Cabling
Twisted-pair segments can be connected with an Unshielded Twisted Pair (UTP) or Shielded
Twisted Pair (STP) cable. The cable must comply with the IEEE 802.3u 100Base TX standard
(e.g. Category 5, 5e, or 6, 6e). The cable between the equipment and the link partner (switch,
hub, workstation, etc.) must be less than 100 meters (328 ft.) long.
*Note: Cable size should be between 18~20 AWG and the torque should be tightened to
5lbs.
The Small Form-factor Pluggable (SFP) is a compact optical transceiver used in optical
communications for both telecommunication and data communication applications.
