1. Overview
This series are (PoE) Ethernet switches with 4 / 8 / 16 port Gigabit
Ethernet + 2 port 1000Mbps SFP (PoE version available) with console
port. The Ethernet switch uses the Layer 2 protocol, which is required
in the industry to ensure the stability of the communication network.
The switches in this series have low power consumption and a fanless
design, so there is no noise. They support a wide operating
temperature range of -40~80°C and offer good electromagnetic
compatibility (EMC) to ensure stable operation in harsh industrial
environments and quickly cater to industrial applications such as
factory automation, intelligent transportation and video surveillance.
A stable network terminal provides a secure and reliable solution.

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
48V DC to 57V DC
