5. Interface Definition
5.1 10/100/1000Base-TX Ethernet interface:
This switch provides MDI/MDI-X self-identification with cable support
on all 10/100/1000Base-TX ports. In use, the Ethernet port of the
switch can be connected with other Ethernet terminal devices through
network cables (direct or cross). Please use Class 5 shielded twisted
pair. The Ethernet port pin definition is shown in the following figure:
RJ45 port supports automatic MDI/MDI-X operation, you can use a
straight line to connect to the PC or server, connect to other switches
or hubs. In the through line (MDI), pins 1, 2, 3, 4, 5, 6, 7, 8 correspond
to the connection;

6
For the MDI-X port of a switch or hub, cross lines are used: 1-3, 2-6,
3-1, 6-2, 4-7, 5-8, 7-4, 8-5.10Base-T/100Base-T (X) pins are defined as

5.2 1000base-FX Ehernet interface
This device provides 1000Base single-mode dual-
fiber SC module, and multi-mode like LC, ST as optional.
5.2.1 Patch cord classification
According to the transmission mode of light in the fiber, it can be
divided into multi-mode fiber and single-mode fiber. Multimode fiber
has a thick glass core (50 or 62.5μm), which can transmit light in
various modes. However, the high inter-mode dispersion limits the
frequency at which digital signals can be transmitted, so multimode
fibers can be transmitted over relatively close distances (typically only
a few kilometers).
The single-mode fiber has a very thin glass core (core diameter, usually
9 or 10μm) and can transmit only one mode of light. Therefore, it’s
inter – module dispersion is very small, and it is suitable for remote
communication. Under normal circumstances, the skin is orange for
multi-mode, yellow for single mode.

7. Installation caution
7.1 Installation precautions
In order to avoid damage to equipment and personal injury caused
by improper use, please follow the following precautions:
In order to avoid damage caused by falling of the equipment,
please put the equipment in a stable environment.
When supplying power to the equipment, pay attention to confirm
the range of power supply voltage, as well as the positive and
negative poles of the power supply, so as not to damage the
equipment by wrong operation.
In order to reduce the risk of electric shock, ensure that the
equipment is well grounded in the working environment.
No matter when, please do not arbitrarily remove
the equipment shell.
When placing the switch, please avoid the area with dust and
strong electromagnetic interference

7.2 Din rail installation:
The first step is to check the grounding and
stability of the guide rail: the guide rail slot of the
switch is clamped into the guide rail; The second
step: from the center to both sides of the guide
rail positioning screws in order. Step 3: Use
screws to fix the mounting rail card slot on the
fixed guide groove at both ends of the guide rail
to ensure that the guide rail and the switch are
fixed on the guide rail vertically and stably.
7.3 grounding
Fix the grounding wire to the grounding screw
above the switch, and ensure good reliable
connection of the grounding system.
7.4 Power Connection
Insert the power cord into the specified position of the 6-core terminal,
and insert the terminal into the standard power supply inlet (P+1 and
P-1 input corresponding to the first power supply P1, and P+2 and P-2
input corresponding to the second power supply P2). The available
voltage standard of the power supply is supported from 12VDC to
52VDC
