1Introduction
The DN-651139, DN-651145 Industrial network switch provide 8 x 10/
100/ 1000Mbps RJ45 ports and 4 Gigabit Combo ports. The RJ45 ports
from 1-8 support PoE power supply with a maximum of 30W for each
port. DN-651139, DN-651145 offers excellent security policy, QoS policy,
and rich VLAN function. Additionally, it has a ring network function that
allows you to set up a ring network. With this feature, the switches
form a ring network topology manually. The ring network is redundant,
highly reliable, and won't affect data forwarding in case a link is broken.
The device is designed with a no-fan, low power consumption design,
making it easy to use, compact, and beautiful. It is also simple to install.
The product meets Ethernet standards, has lightning protection, static
protection mechanisms, and operates in a temperature range of -40°C
to 75°C. This guarantees stable performance, safety, and reliability. V1
can be widely used in various broadband data transmission fields such
as intelligent transportation, telecommunications, security, financial
securities, and customs, among others.
2Features
2.1Product Overview
8-Port Gigabit + 4G Combo Is a ring-network industrial-grade Managed
PoE Switch independently developed by our company, providing
8*10/100/1000Mbps adaptive RJ45 ports and 4*1000Mbps Combo
ports. Each RJ45 port supports MDI/MDIX automatic rollover and wire-
speed forwarding. Ports 1-8 support PoE power supply. PoE ports
automatically detect PD devices and supply power to PD devices that
comply with IEEE 802.3af/at standards. Each port can provide up to
30W power.
The device offers perfect security policies, QoS policies and extensive
VLAN functions as well as a ring network function. A ring network can
be set up, the switches form a ring network topology by hand. Its
redundancy, high reliability and other functions can be set in the ring
network. When a connection is broken, data forwarding in the
network is not affected.

8-Port Gigabit + 4G Combo Port description:
10/100/1000Mbps RJ45 Ports
Supports 10Mbps, 100Mbps, or 1000Mbps rate adaptation, auto-MDI
/MDIX, and each port has a corresponding indicator, that is, port
indicators 1-8 as shown on the panel in the figure above.
1000Mbps Combo Ports
The Combo ports is located at the right and upper part of the
panel. It is an optical multiplexing port. Each port has a
corresponding indicator, that is, the port indicator 9-12 shown on
the panel in the figure above.
Console Port
The Console port is used to connect to the serial port of a
computer or other terminal device and manage or configure
Switches.

5.3Side Plate
Side panel of 8-Port Gigabit + 4G Combo Switch
The side panel of the Switch provides 5-position industrial wiring
terminals and power input DC: The DC power input of the Switch is
redundant. The PWR1 and PWR2 power supplies can be used
individually or connected to 2 independent DC power supply
systems. When any power supply system fails, the device can run
normally without interruption, which improves the reliability of
network operation.
Relay port：Alarm port, support machine abnormal alarm function.
This interface needs to be connected to an external alarm device.
When the machine starts abnormally or when the power is on, the
internal relay will close and output the alarm signal in time, which
has the function of automatic alarm, safety protection and isolation
conversion in the circuit.

6Installation Guide
This chapter helps users correctly install and safely use Switches.
6.1Installation Precautions
Precautions: To avoid equipment damage and personal injury, observe
the following precautions:
The Switch room should be dry and ventilated, free from corrosive
gases and strong electromagnetic interference.
The humidity of the Switch equipment room should be 5% to 95%.
Install proper equipment if possible.
The grounding of the Switch shall comply with the grounding
requirements described in this manual, and shall be separately
and well grounded.
Keep a proper distance between the Switch and other devices. Do
not stack other devices with the Switch.
The connection cable between the Switch and the distribution
frame should be standardized and reasonable, and the
distribution frame (box) jumper wire should be concise and clear
to prevent the phenomenon of parallel lines and wires.
To avoid the danger of electric shock, do not open the chassis
without authorization; If any fault occurs, contact professional
maintenance personnel.
Safety Tips:
Ensure that the PGND cable of the power socket is properly
grounded;
Ensure sufficient space for heat dissipation and ventilation of the
Switch. Do not place heavy objects on the Switch.

16
6.2Installation Environment
Before installation, make sure that the proper working environment
is available, including power requirements, adequate space,
proximity to other equipment to be connected, and other equipment
in place. Please confirm the following installation requirements:
Ensure the stability of the workbench and good grounding
Check whether cables and connectors required for installation
are in place (less than 100m)
The product does not provide installation components. Prepare
components of the selected installation type, such as screws,
nuts, and tools, to ensure reliable installation
Power supply: 48V to 57V DC (DN-651139)
12V to 55V DC (DN-651145)
Environment: operating temperature: -40°C to 75 °C relative
humidity: 5% to 95%.
6.3Installation
DIN-Rail Installation
The 45mm standard DIN-Rail installation is very convenient for most
industrial applications. The installation steps are as follows:
Check whether the installation accessories of DIN-Rail guide
tools are available (installation accessories are provided for this
product).
Check whether DIN-Rail is firmly fixed, whether there is a
suitable place to install the product.
Clamp the lower part of the DIN-Rail connecting seat of the
product accessories into the DIN-Rail (lower part with spring
support), and then clamp the upper part of the connecting seat
into the DIN-Rail (lower part clamp a little, slightly force to keep
the balance of the equipment stuck into the upper part).

18
Power on
Power on: First insert the power terminal of the power cable into
the power port of the device, then plug in the power plug and
power on. After the Switch is started, the Switch automatically
initializes. If all port indicators are on and then off, the system is
successfully reset, and the power LED indicator is always on.
Power off operation: Unplug the power plug first, and then
remove the wiring part of the terminal. Please pay attention to
the above operation sequence.
Wall Mount Installation
The following describes how to install a Switch on the wall.

19
Schematic diagram of wall mounted installation of industrial machine
Remove the DIN-Rail mounting plate on the rear board of the
Switch;
Install the wall mounting board on the Switch as shown below.
Four wall screws are required to mount the Switch on the wall, as
shown in the figure above.
When fixing the screws to the wall, do not screw the screws into
the wall completely. Leave a space of about 2 mm for sliding the
wall panel between the wall and the screws.
After securing the screws to the wall, place the 4 screw heads
through most of the keyhole, then place the Switch vertically and
tighten the screws to increase stability.
