Overview
Introduction
This user manual is suitable for the products as follows:
•5-port 10/100TX Unmanaged Industrial Switch
•8-port 10/100TX Unmanaged Industrial Switch
The unmanaged industrial switch is a cost-effective solution and meets
the high reliability requirements demanded by industrial applications.
High-Speed Transmissions
The Industrial switch includes a switch controller that can automatically
sense transmission speeds (10/100 Mbps). The RJ-45 interface can
also be auto-detected, so MDI or MDI-X is automatically selected and a
crossover cable is not required. All Ethernet ports have memory buffers
that support the store-and-forward mechanism. This assures that data
is properly transmitted.
Dual Power Input
To reduce the risk of power failure, the Industrial switch provides +12 ~
48 VDC dual power inputs. If there is power failure, Industrial switch will
automatically switch to the secondary power input.
Flexible Mounting
The industrial switch is extremely compact and can be mounted on a
DIN-rail or a panel, so it is suitable for any space-constrained
environment.
Advanced Protection
The power line of Industrial switch supports up to 3,000 VDC EFT
protection, which secure equipment against unregulated voltage and
make systems safer and more reliable. Meanwhile, 4,000 VDC ESD
protections for Ethernet ports make Industrial switch more suitable for
harsh environments.

2
Wide Operating Temperature
The operating temperature of the Industrial switch is between -40 ~ 80
℃(wide operating temperature model) or -10 ~ 70 ℃(standard model).
With such a wide range, you can use the Industrial switch in some of the
harshest industrial environments that exist.
Easy Troubleshooting
LED indicators make troubleshooting quick and easy. Each 10/100
Base-TX port has 2 LEDs that display the link status, transmission
speed and collision status. Also the three power indicators P1, P2 and
Fault help you diagnose immediately.

Hardware Description
In this paragraph, we will introduce the Industrial switch’s hardware
spec, port, cabling information, and wiring installation.
Front Panel
The Front Panel of the 5-port and 8-port 10/100BaseTX Industrial
Switch is shown as below.
Front Panel of the 5-port & 8-port 10/100BaseTX Industrial Switch

Top View
The top panel of the 5-port & 8-port 10/100BaseTX Industrial Switch is
equipped one terminal block connector of two DC power inputs.
Top Panel of the 5-port & 8-port 10/100BaseTX Industrial Switch
Wiring the Power Inputs
Please follow the steps below to insert the power wire.
1. Insert the positive and negative wires into the V+ and V- contacts on the
terminal block connector.
2. To tighten the wire-clamp screws for preventing the DC wires to loose.

7
Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of terminal block connector as the
picture shows below. Inserting the wires, it will detect the fault status
which the power is failure or port link failure (for managed model) and form
an open circuit.
Note
The wire gauge for the terminal block should be in the 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.
Insert the wires into the fault alarm contact (No. 3 & 4)

8
LED Indicators
There are few LEDs display the power status and network status
located on the front panel of the Industrial switch, each of them has its
own specific meaning as below table.

Ports
RJ-45 ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for
10Base-T or 100Base-TX devices connections. Auto MDI/MDIX means
that you can connect to another switch or workstation without changing
straight through or crossover cabling. See figures as below for straight
through and crossover cable schematic.

Note
“+” and “-” signs represent the polarity of the wires that make up
each wire pair.
All ports on this industrial switch support automatic MDI/MDI-X
operation, you can use straight-through cables (See Figure below) for
all network connections to PCs or servers, or to other switches or hubs.
In 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 shows the 10BASE-T/ 100BASE-TX MDI and
MDI-X port pin outs.

Cabling
Use the four twisted-pair, Category 5 cabling for RJ-45 port connection.
The cable between the converter and the link partner (switch, hub,
workstation, etc.) must be less than 100 meters (328 ft.) long.

Mounting Installation
DIN-Rail Mounting
The DIN-Rail is screwed on the industrial switch when out of factory. If
the DIN-Rail is not screwed on the industrial switch, please see the
following figure to screw the DIN-Rail on the switch. Follow the below
steps to hang the industrial switch.
1. Use the screws to screw on the DIN-Rail on the industrial switch
2. To remove the DIN-Rail, reverse the step 1.

12
3. First, insert the top of DIN-Rail into the track.
4. Then, lightly push the button of DIN-Rail into the track.
5. Check the DIN-Rail is tightly on the track.
6. To remove the industrial switch from the track, reverse steps above.

13
Wall Mount Plate Mounting
Follow the steps below to mount the industrial switch with wall mount plate.
1. Remove the DIN-Rail from the industrial switch; loose the screws to
remove the DIN-Rail.
2. Place the wall mount plate on the rear panel of the industrial switch.
3. Use the screws to screw the wall mount plate on the industrial switch.
4. Use the hook holes at the corners of the wall mount plate to hang the
industrial switch on the wall.
5. To remove the wall mount plate, reverse steps above.

14
Hardware Installation
In this paragraph, we will describe how to install the 5-port or 8-port
10/100Base-TX Industrial Switch and the installation points for the attention.
Installation Steps
1. Unpack the Industrial switch packing.
2. Check the DIN-Rail is screwed on the Industrial switch. If the DIN-Rail is
not screwed on the Industrial switch. Please refer to DIN-Rail Mounting
section for DIN-Rail installation. If you want to wall mount the Industrial
switch, then please refer to Wall Mount Plate Mounting section for wall
mount plate installation.
3. To hang the Industrial switch on the DIN-Rail track or wall, please refer to
the Mounting Installation section.

15
4. Power on the Industrial switch. How to wire the power; please refer to the
Wiring the Power Inputs section. The power LED on the Industrial switch
will light up. Please refer to the LED Indicators section for meaning of
LED lights.
5. Prepare the twisted-pair, straight through Category 5 cable for Ethernet
connection.
6. Insert one side of Category 5 cables into the Industrial switch Ethernet
port (RJ-45 port) and another side of category 5 cables to the network
devices’ Ethernet port (RJ-45 port), ex: switch, Pc or Server. The UTP port
(RJ-45) LED on the Industrial switch will light up when the cable
connected with the network device. Please refer to the LED Indicators
section for LED light meaning.
Note
Be sure the connected network devices support MDI/MDI-X. If it
does not support, then use the crossover category 5 cable.
7. When all connections are all set and LED lights all show in normal, the
installation is complete.

Troubles shooting
Verify that you are using the right power cord/adapter (DC 12-48V),
please don’t use the power adapter with DC output bigger than 48V, or it
will burn this converter down.
Select the proper UTP cable to construct your network. Please check that
you are using the right cable. Use unshielded twisted-pair (UTP) or shield
twisted-pair (STP) cable for RJ-45 connections: 100ΩCategory 3, 4, or 5
cable for 10Mbps connections or 100ΩCategory 5 cable for 100Mbps
connections. Also be sure that the length of any twisted-pair connection
does not exceed 100 meters (328 feet).
Diagnosing LED Indicators:the Switch can be easily monitored through
panel indicators to assist in identifying problems, which describes
common problems you may encounter and where you can find possible
solutions.
IF the power indicator does not light on when the power cord is plugged in,
you may have a problem with power cord. Than check for loose power
connections, power losses or surges at power outlet. IF you still cannot
resolve the problem, contact your local dealer for assistance.
If the Industrial switch LED indicators are normal and the connected
cables are correct and the packets still cannot transmit. Please check your
system’s Ethernet devices’ configuration or status.
