2.5 Ethernet Ports
●RJ45 Ports
RJ45 Ports (Auto MDI/MDI-X): The RJ45 ports are auto-sensing for 10Base-T, 100Base-TX, or 1000Base-T connections.
Auto MDI means that the switch can connect to another switch or workstation without changing the straight-through or
crossover cabling. See the figures below for straight-through and crossover cabling schematics.

2.6 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the RJ45 port connections. The cable between the switch
and the link partner (switch, hub, workstation, etc.) must be less than 100 meters (328 ft.) in length.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications for both
telecommunication and data communication applications.

2.9 Grounding Note
Grounding and wire routing help limit the effects of noise due to Electromagnetic Interference (EMI). Run the ground
connection from the ground screw to the grounding surface prior to connecting devices. The grounding screw symbol is
shown below in Figure 2.5.
Figure 2.5 - Grounding Screw Symbol
Caution: Using a shielded cable achieves better electromagnetic compatibility.
Attention: L'utilisation d'un câble blindé permet une meilleure compatibilité électromagnétique

3 Mounting Installation
3.1 Rack Mounting
This switch comes with a rack-mounted kit can be mounted in a EIA standard size, 19-inch rack. It can be placed in a
wiring closet with other equipment.
Perform the following steps to rack-mount the switch.
1. Position one plate to align with the holes on one side of the hub and secure it with the smaller plate screws. Then,
attach the remaining plate to the other side of the switch.
Figure 3.1 - Attach Mounting Plates with Screws
2. After attaching both mounting plates, position the switch in the rack by lining up the holes in the plates with the
appropriate holes on the rack. Secure the switch to the rack with a screwdriver and the rack-mounting screws.

4 Hardware Installation
4.1 Installation Steps
This section will explain how to install the industrial Ethernet switch:
Caution: This device is intended for indoor use.
Attention: Cet appareil est destiné à une utilisation en intérieur.
Caution: The device is intended to be installed in an industrial control enclosure and panel.
Attention: L'appareil est destiné à être installé dans une armoire de commande et un panneau industriels.
Installation Steps
1. Unpack the industrial Ethernet switch from the original packing box.
2. Check if the Rack-mount bracket is screwed on the industrial Ethernet switch.
●If the Rack-mount is not screwed on the industrial Ethernet switch, please refer to the Rack Mounting section
for Rack-mount installation.
3. To hang the industrial Ethernet switch on a Rack-mount or wall, please refer to the Mounting Installation section.
4. Power on the industrial Ethernet switch and 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 RJ45 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 (RJ45) LED on the industrial Ethernet switch will turn on when the cable is connected to

4.2 Maintenance and Service
●If the device requires servicing of any kind, the user is required to disconnect and remove it from its mounting.
The initial installation should be done in a way that makes this as convenient as possible.
●Voltage / Power lines should be properly insulated as well as other cables. Be careful when handling them so as
to not trip over.
●Do not under any circumstance insert foreign objects of any kind into the heat dissipation holes located in
the different faces of the device. This may not only harm the internal layout, but might cause harm to users
as well.
●Do not under any circumstance open the device for any reason. Please contact your dealer for any repair
needed or follow the instructions within the manual.
●Clean the device with dry soft cloth.
4.3 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 RJ45 connections: 100Ω Category 5e for 10/100Mbps. 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 identify if any problems exist.
○Please 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.
○Please 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.
