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.

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.
◼To connect the transceiver and LC cable, please follow the steps below:
First, insert the SFP transceiver module into the SFP slot as shown below in Figure 2.7.
Notice that the triangle mark is at the bottom of the SFP slot. Figure 2.8 shows SFP
transceiver module was inserted.
Second, insert the fiber cable of the LC connector into the transceiver as shown below in Figure
2.9.
To remove the LC connector from the transceiver, please follow the steps shown below:
1. Press the upper side of the LC connector from the transceiver and pull it out to release as
shown below in Figure 2.10.
2. Push down the metal clasp and pull the transceiver out by the plastic part as shown below in
Figure 2.11.

2.7 Wiring the Power Inputs
Please follow the 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 2.12.
2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in Figure
2.13.
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 2.14. By inserting the
wires, it will detect the fault status
including power failure or port link
failure and form a normally open
circuit.
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.

4. Hardware Installation
4.1 Installation Steps
This section will explain how to install Antaira Technologies’ LNX-2004G-SFP(-T):
Installation Steps
1. Unpack the industrial Ethernet switch from the original packing box.
2. Check if the DIN-Rail bracket is screwed on the industrial Ethernet switch.
•If the DIN-Rail is not screwed on the industrial Ethernet switch, please refer to the
DIN-Rail Mounting section for DIN-Rail installation.
•If it is required to wall mount the industrial Ethernet switch, please refer to the Wall
Mounting section for wall mounting installation.
3. To hang the industrial Ethernet switch on a DIN-Rail or wall, please refer to the Mounting
Installation section.
4. Power on the industrial Ethernet switch, then the power LED light will turn on.
•For the help on how to wire power, please refer to the Wiring the Power Inputs
section.
•Please refer to the LED Indicators section for LED light indication.
5. Prepare the twisted-pair, straight-through category 5 cable for Ethernet connection.
6. Insert one side of the RJ-45 cable into the switch’s Ethernet port and on the other side into
the networking device’s Ethernet port, e.g. switch, PC, or server.
•The Ethernet port’s (RJ-45) LED on the industrial Ethernet switch will turn on when
the cable is connected to the networking device.
•Please refer to the LED Indicators section for LED light indication.
7. When all connections are set and the LED lights all show normal, the installation is complete.

6. Troubleshooting
•Always verify the right power cord or adapter is being used. Never use a power supply or
adapter with a non-compliant DC output voltage or it will burn the equipment.
•Select the proper UTP or STP cable in order to construct the network. Use an unshielded
twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections: 100Ω
Category 5e for 10/100/1000Mbps. Also be sure that the length of any twisted-pair
connection does not exceed 100 meters (328 feet).
•Diagnosing LED Indicators: To assist in identifying problems, the switch can be easily
monitored with the LED indicators which help to identity if any problems exist.
oPlease refer to the LED Indicators section for LED light indication.
•If the power indicator LED does not turn on when the power cord is plugged in, the user
may have a problem with the power cord. Check for loose power connections, power
losses or surges at the power outlet.
oPlease contact Antaira for technical support service, if the problem still
cannot be resolved.
•If the industrial switch LED indicators are normal and the connected cables are correct but
the packets still cannot transmit, please check the system’s Ethernet devices’ configuration
or status.
