1. Overview
Antaira Technologies’ LNP-2004G-SFP series is a 20-port industrial grade gigabit Ethernet
unmanaged switch. This rugged switch is enclosed in a metal IP30 rated design with
16*10/100/1000 RJ45 Ethernet ports that are IEEE 802.3af/at complaint (Power over Ethernet)
and 4*100/1000 dual rate SFP slots. This series is the perfect solution for any application
requiring high bandwidth, long-distance communication, and high density PoE connectivity.
The LNP-2004G-SFP series is a power sourcing device that supports PoE+ when an input
voltage power of 48~55VDC range is applied. This product series 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 wide operating temperature range
models in STD: -10°C to 65°C and EOT: -40°C to 75°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 unit is also ideal for any other application requiring a high port
count solution.

2.5 Ethernet Ports
◼RJ-45 Ports (Auto MDI/MDIX):
The RJ-45 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.
◼RJ-45 Pin Assignments (Table 2.2)

All ports on this industrial Ethernet switch support automatic MDI/MDI-X 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 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-T and MDI/MDI-X port pin outs.
Note:
The “+” and “-” signs represent the polarity of the wires that make up each wire pair.
