2.5 Ethernet Ports
• RJ-45 Ports
RJ-45 Ports (Auto MDI/MDIX): The RJ-45 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.

Note: The “+” and “-”signs represent the polarity of the wires that make up each wire pair.
All ports on this industrial Ethernet switch support automatic MDI 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 cabling, pins 1, 2, 3, and 6 are at one end of
the cable and are connected straight through to pins 1, 2, 3 and 6 at the other end of the
cable. The table below (Table 2.4) shows the 10BASE-T/100BASE-TX/1000BASE-T MDI

The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications for
both telecommunication and data communication applications.
Caution: Please employ optional optical transceiver (SFP/Fixed Fiber) that complies with IEC-60825-1
and classified as Class 1 laser product.
Attention: Veuillez utiliser un émetteur-récepteur optique en option (SFP/fibre fixe) conforme à la norme
IEC-60825-1 et classé comme produit laser de classe 1.
2.7 Wiring the Power Inputs
Caution: Please follow the steps below when inserting the power wire.
Attention: Veuillez suivre les étapes ci-dessous lors de l'insertion du câble d'alimentation.
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 2.6.
2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below
in Figure 2.7.

Caution:
•Only use copper conductors, 125°C, tighten to 5 lbs.
•The wire gauge for the terminal block should range between 18~20 AWG.
Attention:
•Utilisez uniquement des conducteurs en cuivre, 125°C, serrez à 5 lb.
•Le calibre des fils du bornier doit être compris entre 18 et 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 2.8. By inserting the wires, it will detect the fault status including power failure or
port link failure (managed industrial switch only) and form a normal open circuit. An example is
shown below in Figure 2.8.
Caution:
•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.
Attention:
•Le calibre des fils du bornier doit être compris entre 12 et 24 AWG.
•Si vous n'utilisez qu'une seule source d'alimentation, connectez les
broches 1 à 5 et les broches 2 à 6 pour éliminer l'alarme de panne de
courant.

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 blow in Figure 2.9.

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 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 you want 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 and then the power LED light will turn on.
• If you need help on how to wire power, please refer to the Wiring the Power Inputs
section.

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 user 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
• Verify the right power cord/adapter, never use power supply/adapter with noncompliant DC output
voltage, or it will burn the equipment.
• Select the proper UTP/STP cable to construct the network with using the right cable. Use unshielded
twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections: 100Ω Category 5e/above
cable for 10M/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 through
LED indicators, which describe common problems a user may encounter and where the user can find
possible solutions.
• 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 or Antaira’s authorized channel partners 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.
