5. Internal storage and forwarding mechanismSwitch Panel
Side panel: P1 and P2 are the number of connecting terminals, P+1
and P-1 are respectively to the positive and negative poles to be
connected; Earthing screw, used for earthing equipment.
Front panel: The yellow light on the port is the LINK light, which is on
when the connection is established and the data transmission is
flashing.
The green light is PoE light, which is only on when the switch port is
supplying power to the PD devices. Power indicator light is on when
connecting with Power.

6. Interface Definition
6.1 10/100/1000Base-TX Ethernet interface:
This series of switches 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:

11
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; 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, 8-5.1000Base-T (X) pins are
defined as follows:

6.2 1000base-FX Ehernet interface
This device provides 1000Base single-mode dual fiber SC module, and
multi-mode like LC, ST as optional.
6.2.1 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.

8. Installation caution
8.1 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

14
8.2 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.
8.3 grounding
Fix the grounding wire to the grounding screw above
the switch, and ensure good reliable connection of
the grounding system.
8.4 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 48VDC to
57VDC
