2.2. Ethernet RJ45 Port
Each RJ45 port with adaptive function, supporting auto MDI/MDI-X
connection, can connect the switch with terminal equipment, servers, hubs or
other switches via straight line/cross-over cable. Each RJ45 port supports
IEEE802.3x adaptive function, so the optimum transmission mode (half or full
duplex) and data rate (10/100/1000Mbps) can be automatically selected (the
other connected equipment must meet this feature). If the equipment
connected to these ports does not support adaptive function, the port will force
itself to work at the same rate as the other parties, avoiding full/half duplex
mismatch, the transfer mode will default to be half-duplex mode, and the flow
control will be automatically disabled. Gigabit TX port can support up to
1000Mbps.
MISCOM7028GX/MISCOM8028GX Series Switches provide 8 RJ45 ports
at most, it can be connected with other Ethernet terminal equipment via
straight line/cross-over cable in use. RJ45 pin number seriation is shown as
below.
RJ45 connector pin number seriation picture.
With supporting auto MDI/MDI-X adaptive function, this series switches
can connect with other Ethernet switch by using of CAT. 5 straight line and
cross-over cable, providing flexible choice for cable in practical use.
At the time when RJ45 port is 10/100Based-TX, pin definition is shown in

2.3. SFP FX Port
The Gigabit FX port of the switch is 1000Base-LX full-duplex
single-mode/multi-mode FX port, using SFP hot-swappable device, and the
type of FX port is LC. The FX port needs to be used in pair (TX and RX are in

pair), the TX port is the fiber transmitting end, connecting with the fiber
receiving end RX of the other remote switch FX port. The RX port is the fiber
receiving end, connecting with the fiber transmitting end TX of the other remote
switch FX port. Two redundant 1000Base-LX FX ports can be used to establish
a fiber redundant ring network. If system fails, the ring network redundancy
recovery time is less than 20ms, which can effectively improve the reliability of
network operation.

2.7. Ground
The panel of the MISCOM7028GX/MISCOM8028GX Series Switches has
a grounding screw. Press one end of the grounding wire to the cold-pressing
terminal and fix it to the grounding hole of the housing with the grounding screw.
Connect the other end of the grounding wire to the ground reliably. The
grounding wire cross section is not less than 2.5 ㎜².
Important notes:
Power on operation: Connect the power supply cable with terminal
blocks of the equipment according to above diagram definition, then power
on.
Power off operation: Plug out the socket first, then take down the
power cable.
Please follow the above operation order.
The supported power specifications of the device is 220VAC/DC.
Please confirm whether the power supply is compliance with the requested
power specification printed on the label of the device before powering on,
so as not to damage the device.

3. Hardware Installation
3.1. Installation Requirements
The Industrial Ethernet Switch is a kind of single structure that fits
rack-mounting installation. Before installing, first confirm suitable working
environment for installation, including power requirements, sufficient space,
being closed to other network equipment to be connected. Please confirm the
following installation requirements.
Power requirements: The standard product is charged by AD220 power
supply. For other power supply methods, please refer to the product label
printed on the housing and related user manual.
Environmental requirements: Temperature -40 °C ~ 70 °C, relative
humidity 5 ~ 95% (no condensation).
Grounding resistance requirement: <5
According to the contract configuration requirements, check whether the
fiber cables are in place, fiber optic connectors are appropriate.
Avoid direct sunlight and away from heat sources or areas with strong
electromagnetic interference.
Standard 19’’ U rack-mountable installation. Check for suitable cables
and connectors.
Attention:
Make sure the power cable is disconnected before installing or
connecting Ethernet switch. Calculate Max current of each power cable and
public cables, observing all electric information so as to obtain allowed Max
current of wires in different width. If exceeding the Max current, wires will
overheat, causing serious damage to the equipment.
Meanwhile MUST pay attention on the following items:
Separate the power cable and other cables, if the two paths have to
cross, MUST make sure that the intersection of these cables are vertical.
Signal wires or communication wires and power cables cannot be laid 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 wires should be separated. The rule of thumb is that wires
with the same electrical characteristics can be bundled together. Separate
the input and output wires. It is highly recommended that all equipment wires
in the system should be labeled when necessary.

MISCOM7028GX/MISCOM8028GX Series Industrial Ethernet Switch
- 12 -
The switch should be connected to the protection ground: Grounding
and laying wires will effectively suppress the effects of noise caused by
electromagnetic interference. A ground connection should be made before
connecting the equipment, from the ground screw to the ground surface.
3.2. Mainframe Installation
Mainframe picture as below.
Mainframe picture
For most industrial applications, it is very convenient to install in a 19-inch
rack. Check the rack installation before mainframe installation, including the
following two items:
Is there enough room for installing this product?
Is there a power supply suitable for this product?
3.3. Cable Connection
After the correct installation, the cable can be installed and connected,
mainly including the cable connection of the following ports.
Server interface connection
The terminal equipment Gigabit TX ports provided by the product is

MISCOM7028GX/MISCOM8028GX Series Industrial Ethernet Switch
- 13 -
10/100/1000Based-TX. Connect the terminal equipment with straight line cable,
connect the network equipment with cross-over cable.
Connecting network managed port
The CONSOLE port of the product can be connected to the serial port of
the control computer.
Connecting power
After all other cables have been connected, then connect the power
supply that meets the product specifications.
3.4. Laying Cables
Laying cables should be compliance with the following items:
Check whether the specifications, model and quantity of all cables are
consistent with the construction drawing design and contract requirements
before laying the cables.
Before the cable is laid, check whether the cable is damaged, whether
there are quality certificates such as the factory record and quality assurance.
The specifications, quantity, routing direction, and placement position of
the required laying cables should meet the construction drawing design
requirements. The laying length of each cable should be determined according
to the actual location.
User cable and power cable should be placed separately.
There MUST be no disconnection in the middle of the laying cable, or a
connector in the middle.
The cable should be straight and neatly discharged in the aisle, and the
curve should be even, smooth and straight.
The cable should be straight in the channel, and should not exceed over
the channel, block other access holes, and should be tied and fixed at the
cable exit channel or cable bend.
When the cables power cables and ground cables are placed in the
same slot, the three types of cables cannot overlap and mix. If cable is too long,
the cable grounding plate must be placed in the middle of the cable tray, and it
cannot be pressed on other cables.
Prevent the cable from knotting, reduce the bend and avoid small bend
radius when laying the fiber on the tail. The lashing should be tight and not too
tight. When placed on the cable tray, it should be placed separately from other
cables.
The two ends of the cable should have corresponding identifiers. The
content of the identification should be concise and easy to maintain.
Attention:

MISCOM7028GX/MISCOM8028GX Series Industrial Ethernet Switch
- 14 -
When laying the fiber on the tail, it is necessary to prevent the cable
from being knotted, reduce the bend and avoid small bend radius. If the
bend radius is too small, the link optical signal will be seriously depleted and
also it will affect the quality of communication.
