1. Overview
Antaira Technologies’LNP-1202G-SFP industrial gigabit unmanaged Ethernet switch series is
IP30 rated and DIN-Rail mountable. Each unit is designed with 10 gigabit Ethernet ports, eight of
which are IEEE 802.3at compliant (power-over-Ethernet plus) and the unit has two dual rate
(100/1000) SFP slots. The LNP-1202G-SFP is an ideal solution for applications that demand
high bandwidth, PoE connectivity and long distance communication.
The LNP-1202G-SFP is a power sourcing device that supports PoE+ when an input voltage
power within the 48~55VDC range is applied. This product series provides high EFT and ESD
protection to prevent any unregulated voltage. The power input design provides multiple power
input connections supporting a power redundancy feature designed with reverse polarity
protection. In addition, the built-in relay warning function alerts maintainers when power failures
occur.
The LNP-1202G-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 any special needs for industrial automation, PoE security or
outdoor applications with harsh weather environments.

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.

The following figures show the 10,100, and 1000 Ethernet RJ-45 pin outs.
2.6 Cabling
Use the four twisted-pair, category 5e, or the above cabling for 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.) long. When working with high power PoE+ applications when the line wattage
will be around 30 watts per port, it is suggested to use category 6 Ethernet cables.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
communications for both telecommunication and data communication applications.

2.7 Wiring the Power Inputs
Please follow below steps to insert 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 Figure 2.14.
2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in Figure
2.15.
Note
Only use copper conductors, 60/75°C, tighten to 5 lbs.
The wire gauge for the terminal block should range between 18~20 AWG.

2.8 Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of the terminal block connector as the picture shows below
in Figure 2.16. By inserting the wires, it will detect the fault status including power failure or port
link failure (managed industrial switch only) and form a normally open circuit. An application
example for the fault alarm contact is shown below in Figure 2.16.
Note
The wire gauge for the terminal block should range between 12 ~ 24 AWG.
If only using one power source, jumper Pin 1 to Pin 5 and Pin 2 to Pin 6 to
eliminate power fault alarm.
