The product provides high-speed packet forwarding capability and
ample backplane bandwidth to ensure clear and smooth image
transmission. It is embedded in static electricity and surge
protection circuit to improve product stability. It also supports VLAN
configuration mode, which enables network storm suppression,
protects security information, and prevents the spread of viruses
and network attacks. It fully meets the requirements of network
video surveillance system.

5.3 DIP switch
The switch defaults to the standard network mode at the factory,
and the dial keys ①and ②are in the off position. After the device
is power on, all of ports are interoperable.
One-to-one isolation: Dial key ①to on position, dial key ②
default off position. After the device is power on, it starts the one-
to-one isolation mode configuration and implements the
corresponding ports of the two ports. In this case, the ports on the
same device cannot be forwarded to each other. They can only
communicate with the corresponding port on the peer device.
Port Isolation: Dial key ②to on position, Dial key ①default off
position. After the device is power on, port isolation is achieved. The
RJ45 ports cannot communicate with each other, the
communication takes place between the SFP port and the individual
RJ45 ports.
Long distance mode: Dial key ①and ②to on position. After the
device is power on, the long-distance mode configuration is enabled
and the electrical port rate is 10Base-T. The transmission distance of
the electrical port is increased. At this time the device port
transmission distance of 0-330 meters.
Notes
1 to 1 isolation mode must require two identical
switches, through the optical port docking network can
be used.

6. Important function
6.1 Port Isolation
The switch cannot carry out data transfer between each other, only
to the optical port to communicate, so the data conversion more
efficient, the system is running more secure.
6.2 One-to-one Isolation
When two switches A and B are connected through the optical
interface, the A switch port 1 can only communicate with the B
switch port 1. Similarly, A switch port 2 can only communicate with
B switch port 2, and so on. To establish one-to-one isolation mode
between A and B switches’ RJ45 ports, it requires 2pcs of same
switch. It prevents the network storm, eliminating the paralysis of
the system.

8
6.3 Long distance mode
By default, the switch electrical port transmission distance of 0-100
meters, open long distance mode, the electrical port for 10Mbit/s,
to meet the high-definition video transmission bandwidth while
increasing the maximum transmission distance of 330 meters. Thus
enabling the ability to install IP cameras at the front of the field.
7. Installation
7.1 Precautions
When placing the switch, please pay attention to stability, drop will
cause serious consequences.
Should be in the correct power supply to work properly, please
confirm before using the power supply and switch the power
requirements specified in line.
To reduce the risk of electric shock, do not open the case when the
switch is working, even if it is not charged, do not open it yourself.
When the switch works, the network cable can be inserted or pulled
out at the port without interrupting the work of the switch.
Before cleaning the switch, pull the switch's power plug first, wipe it
with a moisturizing fabric, and do not use liquid cleaning.
Do not place the switch in a watery or humid place and prevent
water and moisture from entering the switch housing.
When placing the switch, please avoid dusty and strong areas of
electromagnetic interference
7.2 Install style
There are two install methods that can be installed on the desktop
and wall mounted.

7.2.1 Install to the desktop
You can place this product directly on a clean, solid, grounded desk.
7.2.2 Wall mounted
You can also place this product on a clean, solid vertical wall. The
installation process is as follows:
1. Fix the mounting brackets with screws
2. Insert the capsules into the holes on the wall. (The capsules are not
included in the package.)
3. Insert the screw into the hole of the dowel. Please use screws with
a diameter of 3-5 mm. Fix the network switch with the screws.
8. Connect the cable
1) Before installation, please turn off the power of each signal
source and the device to be displayed. The installation of the
power supply may cause damage to the transmission equipment.
2) Use the network cable to connect the network camera and
the 1-4 Electrical port of the device respectively;
3) Connecting the optical fiber interface of the device with the
optical fiber interface of the uplink equipment using the optical
fiber line.
4) To connect the power supply equipment.
5) Check whether the installation is correct, equipment damage, to
ensure that all connections are reliable, to the system power.
6) To confirm whether the network equipment, power supply,
work is normal.
