Each RJ45 port has an adaptive function and supports automatic
MDI/MDI-X connection. The switch can be connected to terminal equipment,
servers, hubs, or other switches using straight-through network cables or
crossover network cables. Each port supports IEEE802.3x adaptive, so the
most suitable transmission mode (half duplex or full duplex) and data rate
(10Mbps and 100Mbps) can be automatically selected (the connected device
must also support this feature). If the device connected to these ports does not
support auto-adaptation, the port will force itself to work at the same rate as the
other party to avoid full/half duplex mismatch. The transmission mode will
default to half duplex and flow control will be automatically disabled.

3. Hardware Installation
3.1. Installation Requirements
This industrial Ethernet switch is a single structure. Before installation, you
must first confirm that there is a suitable working environment, including power
requirements, sufficient space, whether it is close to other network equipment
to be connected, and whether other equipment is in place. Please confirm the
following installation requirements:
Power requirements: standard products use 24V power supply. For other
power supply methods, please refer to the product label, the power supply
mark on the shell and the relevant manual
Environmental requirements: temperature -40℃～+85℃, relative humidity
5～95% (no condensation)
Grounding resistance requirements: <5Ω
According to the contract configuration requirements, check whether the
optical cable is laid in place and whether the optical fiber connector is suitable
Avoid direct sunlight, keep away from heat sources or areas with strong
electromagnetic interference
Standard products are installed on DIN rails. Check if there are cables and
connectors required for installation
Attention
Be sure to disconnect the power cord before installing or connecting the
Ethernet switch. Calculate the maximum possible current in each power line
and common line, and observe all electrical information to know the maximum
current allowed by lines of different widths. If the current exceeds the maximum
rated current, the wire will overheat and cause serious damage to the
equipment.
At the same time, you must also pay attention to the following:
Separate the paths of power lines and equipment lines. If the two paths
must cross, make sure that these lines are perpendicular at the intersection. It
is not allowed to lay signal wires or communication wires and power wires in
the same pipe. To avoid interference, wires with different signal characteristics
should be separated. We can use the type of signal transmitted in a line to
determine which lines should be separated. The rule of thumb is that wires with
the same electrical characteristics can be bundled together. Separate the input
line and output line. It is strongly recommended to label all equipment lines in
the system when necessary.
The switch must be connected to the protective ground:

Grounding and wiring can effectively suppress the noise impact caused by
electromagnetic interference. The ground connection should be made before
connecting the equipment, from the ground screw to the ground surface.
3.2. Installation
3.2.1. Din-rail Installation
For most industrial applications, it is very convenient to install with 35mm
standard DIN rail. When you remove the device from the packing box, the DIN
rail connection seat should be fixed on the rear panel of the MIEN2204 series
switch. If MIEN2204 series switches need to be mounted on DIN rail, you
should check the installation of DIN rail before installation. It includes the
following two contents:
Whether the DIN rail is fixed and strong, whether other equipment is
installed on the DIN rail, and whether there is enough space for installing the
switch.
Weather Is there any power supply suitable for the work of this switch on
the DIN rail.
After selecting the installation location of the switch, install the switch on
the DIN rail as follows:
Insert the upper part of the DIN rail into the snap groove of the upper part
of the DIN rail connection seat with a snap spring. Push down slightly on the
top panel of the switch and rotate the device as shown in below
Install MIEN2204 series switches to Dil-rail
cable connection
After the MIEN2204 series switches are correctly installed, the cables can
be installed and connected, mainly including the cable connections of the
following interfaces.
RJ45 interface

MIEN2204 Series Unmanaged Industrial Ethernet Switch
- 9 -
The terminal equipment interface provided by MIEN2204 series switches
is a 10Base-T / 100Base-TX Ethernet RJ45 interface, which uses a DC
network cable to connect to the terminal equipment and a crossover network
cable to connect to the network equipment.
Connecting Power
MIEN2204 series switches use power according to the instructions on the
product label. When all other cables are connected, the power can be
connected
3.3. Fiber Interface Connecting
3.3.1. Fiber Connecting
MIEN2204 series switches provide 100Base-FX full-duplex single-mode or
multimode fiber interfaces. The type of optical fiber interface can choose SC /
ST / FC according to demand.
Attention
This switch uses a laser to transmit signals on fiber optic cables. The
laser meets the requirements of Class 1 laser products, and normal
operation is not harmful to the eyes. However, when the device is powered
on, do not look directly at the optical transmission port and the end face of
the fiber terminator.
The steps to connect pluggable fiber optic modules are as follows:
Remove and keep the rubber sleeve of the SC / ST / FC port. When not
in use, put on a rubber sleeve to protect the fiber optic terminator
Check whether the fiber terminator is clean. Lightly moisten a clean
paper towel or cotton ball and gently wipe the cable plug. A dirty fiber
terminator will reduce the quality of the optical transmission and affect the port
performance
Connect one end of the optical cable to the optical fiber interface and the
other end to the optical fiber interface of another device
After the connection is completed, please check the LINK / ACT indicator
of the corresponding optical port on the front panel.
3.3.2. Laying Cables
The cable layout must meet the following conditions:
Check whether the specifications, models and quantities of all cables are
in compliance with the construction drawing design and contract requirements
before laying out the cables
Before laying the cable, check whether the cable is damaged, whether
there are factory records and quality assurance certificates that prove its
quality

MIEN2204 Series Unmanaged Industrial Ethernet Switch
- 10 -
The specifications, quantity, routing direction, and location of the cables to
be laid should meet the design requirements of the construction drawing. The
wiring length of each cable should be determined according to the actual
location.The user cables and power cables should be laid separately.
There must be no disconnection or joints in the middle of the laid cables
Cables should be laid out neatly in the aisle, and the bends should be
even, smooth and straight
The cable should be straight in the channel, and should not go out of the
channel and block other wire entry and exit holes. The cable should be bound
and fixed at the location of the cable exit from the channel or the cable bend
When the cables, power cords, and ground wires are laid in the same slot,
the cables, power cords and ground wires cannot be overlapped or mixed.
When the cable is too long, the cable must be neatly placed in the middle of the
cable rack, and cannot be pressed on other cables
When laying pigtails, prevent the optical cable from knotting and minimize
the turning points, and the turning radius should not be too small. The lashing
should be moderately tight and not too tight. When laying on the cable rack, it
should be placed separately from other cables
There should be corresponding marks at both ends of the cable, and the
content of the marks is concise and easy to maintain
Attention
When laying pigtails, prevent the optical cable from kinking and minimize
the turning point, and the turning radius should not be too small. If the turning
radius is too small, it will cause serious loss of the link optical signal. Affect the
quality of communication.
