Attention:
Before installing or connecting Ethernet switch please make ensure
disconnect the power line. 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 wires will overheat and cause
serious damage to the equipment.
Also need to pay attention to the following items at the same time.
Separate the paths of power lines and equipment lines. If the two paths
must cross, make sure that these lines are vertical 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 cabling can effectively suppress the noise caused by
electromagnetic interference. Before connect the switch with equipment
please connect GND first. Connected to the grounding screw from the
ground surface.

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:
Sufficient space to install product
suitable power introduction for the work of the product
2.2.3. Cable connection
After correct installation, you can install and connect the cables, mainly
below following interfaces:
Operation port
The terminal device interface provided by the industrial Ethernet switch is
a 10Base-T/100Base-TX Ethernet RJ45 interface,use a straight-through
network cable to connect to the terminal device, and a crossover network cable
to connect to the network device.
Power connection
The standard of the power on our product label could be connected after
all the other cables are ready.
2.2.4. Fiber optic connection
This series of rack-mounted industrial Ethernet switches respectively
provide multiple 100Base-TX single-mode or multi-mode optical fiber
interfaces. The type of optical fiber interface can be selected from SC, FC or
ST.
Attention：
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.

MIEN3024/3026 Rack Mount Industrial Ethernet Switch

For modules with a transmission distance longer 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 out.
The steps to connect the pluggable fiber optic module are as follows:
Remove and keep the rubber boot of the SC, FC or ST port. When not in
use, put on a rubber sleeve to protect the optical fiber terminator.
Check whether the fiber optic 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 interface of the switch,
and the other end to the optical 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. Cable Layout
The cable layout must meet the following conditions:
Check whether the specifications, models and quantities of all cables are
consistent 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.
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
The user cables and power cables are routed separately.
There must be no broken wires or joints in the middle of the laid cables.
Cables should be laid out neatly in the aisle, turn evenly, smooth and
straight turns.
The cable should be straight in the channel, and shall not go beyond the
channel to block other wire inlets and outlets. The cable exits the channel or
the cable turn should be tied and fixed.
When cables, power cords, and ground wires are placed in the same slot,
the cables, power cords, and ground wires cannot overlap or be mixed. When
the cable is too long, the cable must be neatly placed in the middle of the
cabling rack and cannot be placed on other cables.

MIEN3024/3026 Rack Mount Industrial Ethernet Switch
- 11 -
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,It should not be 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 should be concise and easy to maintain.
Attention:
When laying out 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 and affect the quality of communication.
2.3. Testing guide
2.3.1. System self-examination
All the service port indicators on the front panel will flash once when the
device is powered on, which means that the port is working normally. After that,
the corresponding power will be always on. The Run light (system running
status indicator) will flash at intervals of 1s.
2.3.2. Copper port testing
