100M fiber interface
MIEN2018-2S/M and MIEN2026-2S/M have 2 100Base-FX full-duplex
single-mode or multi-mode fiber interfaces, and the connectors can be SC, ST
or FC. Optical fiber interfaces need to be used in pairs (TX and RX are a pair),
TX port is the optical transmitting end, connected to the optical receiving end
RX of the optical interface of another remote switch; RX port is the optical
receiving end, connected to the same optical interface of the same remote
switch The optical transmitter TX.
The 100M fiber interfaces mainly include: SC, ST, FC. As shown in Figure
2-3.

Ethernet RJ45 port
This series of products has 16 or 24 10Base-T/100Base-TX Ethernet
RJ45 ports. Each RJ45 port has an adaptive function and supports automatic
MDI/MDI-X connection. The switch can be connected to terminal devices,

MIEN2016/2018/2024/2026 Rack Mount Industrial Ethernet Switch

servers, hubs or other switches using straight-through network
cables/crossover network cables. Each port supports IEEE802.3x adaptive, so
the most suitable transmission mode (half-duplex or full-duplex) and data rate
(10Mbps or 100Mbps) can be automatically selected (the connected device
must also support this feature). If the devices connected to these ports do not
support auto-negotiation, the ports will send at the correct speed, but the
transmission mode will default to half-duplex.
The power input terminals are shown in Figure 2-4.

2.2. Hardware installation
2.2.1. Installation requirements
The industrial Ethernet switch is a single structure, which can be directly
installed on a 19-inch rack. Before installation, 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 AC220V power supply. For

MIEN2016/2018/2024/2026 Rack Mount Industrial Ethernet Switch
- 6 -
other power supply methods, please refer to the product label, the power
supply label on the housing and the relevant manual
Environmental requirements: temperature -40°C~85°C, relative humidity
5~95% (no condensation)
Grounding resistance requirements: <5
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
The standard product is installed on a 19-inch rack. Check if there are
cables and connectors required for installation
Note:
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. 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.
2.2.2. Host installation
The installation dimensions of MIEN2016 and MIEN2024 are shown in
Figure 2-5.

Figure 2-6 Installation dimensions of MIEN2018-2S/M and MIEN2026-2S/M
For most industrial applications, 19-inch rack installation is very
convenient. The installation situation of the rack should be checked before
installation. It mainly includes the following two contents:
Is there enough space for installing this product
Is there a power supply suitable for the work of this product
When installing, first determine the installation position of the product,
align the mounting holes of the switch with the holes on the rack, and fix it with
4 screws. The recommended specification is M5*14.
2.2.3. Cable connection
After the correct installation, the cables can be installed and connected,
mainly including the cable connections of the following interfaces.
Working interface

MIEN2016/2018/2024/2026 Rack Mount Industrial Ethernet Switch
- 8 -
The terminal device interface provided by this product is a
10Base-T/100Base-TX Ethernet RJ45 interface, which uses a straight-through
network cable to connect to the terminal device and a crossover network cable
to connect to the network device.
Connect to power
When all other cables are connected, you can connect to the power supply
of the product identification specification.
2.2.4. Fiber optic connection
Both MIEN2018-2S/M and MIEN2026-2S/M products provide two
100Base-TX single-mode or multi-mode optical fiber interfaces. The type of
fiber interface can be selected as SC, ST or FC according to requirements.
Note:
This switch uses lasers to transmit signals on fiber optic cables. The
laser meets the requirements of Class 1 laser products, and normal
operation is harmless to eyes. However, when the equipment is powered on,
do not look directly at the optical transmission port and the end face of the
optical fiber terminator.
For modules with a transmission distance greater than 60km, do not use
short optical fibers (below 20km) to connect, so as not to cause the optical
saturation and overpower at the receiving end of the module to burn.
The steps to connect the pluggable fiber optic module are as follows:
Remove and keep the rubber sleeve of the LC, SC or FC port. When not
in use, put on a rubber sleeve to protect the fiber terminator.
Check whether the fiber terminator is clean. Slightly moisten a clean
paper towel or cotton ball, and gently wipe the cable plug. Dirty fiber optic
terminator will reduce the quality of optical transmission and affect port
performance.
Connect one end of the optical cable to the optical fiber interface of the
switch, and the other end to the optical fiber interface of another device.
After the connection is completed, please check the corresponding
LINK/ACT indicator of the optical port on the front panel of the switch. If the
indicator is on, the connection is valid.
2.2.5. Laying cables
The cable layout must meet the following conditions:
Check whether the specifications, models and quantities of all cables are
in accordance with the construction drawing design and contract requirements
before laying out the cables

MIEN2016/2018/2024/2026 Rack Mount Industrial Ethernet Switch
- 9 -
Before laying the cable, check whether the cable is damaged, whether
there are factory records and quality assurance certificates that prove its
quality
The specifications, quantity, routing direction, and location of the cables
to be laid should meet the design requirements of the construction drawing,
and the wiring length of each cable should be determined according to the
actual location
User cables and power cords are laid separately
There must be no broken wires or joints in the middle of the laid cables
The 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 cable entry and exit holes. The cable should be tied
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
Both ends of the cable should have corresponding marks, and the
content of the marks is concise and easy to maintain
Note:
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.
2.3. Simple test
2.3.1. System self-check
All the service port indicators on the front panel will flash once when the
device is powered on, indicating that the port is working normally. After that, the
corresponding Power will always be on, and the Run light (system running
status indicator) will flash at intervals of 1s.
