6Installation the Switch
This part describes how to install your Ethernet Switch and
make connections to it. Please follow the following
instructions in avoid of incorrect installation causing device
damage and security threat.
6.1 Notice the matters
•Before cleaning the switch, unplug the power plug of
the switch first. Do not clean the switch with wet cloth
or liquid.
•Do not place the switch near water or any damp area.
•Prevent water or moisture from entering the switch
chassis.
•Do not place the switch on an unstable case or desk.
The switch might be damaged severely in case of a fall.
•Ensure proper ventilation of the equipment room and
keep the ventilation vents of the switch free of
obstruction.
•Make sure that the operating voltage is the same one
labelled on the switch.
•Do not open the chassis while the switch is operating
or when electrical hazards are present to
avoid electrical shocks.
6.2 Installation environment
Before the installation, should first confirm that there is a
suitable working environment.

6
Installation requirements:
•Avoid direct sunlight, away from the heat source or
strong electromagnetic interference.
•Check cable and connector according to reasonable
configuration requirements, the cable (<100m)
•The product does not provide installation component:
screws, nuts, and other installation tools.
•Power requirements: PD voltage input range 36~57V,
power 60W
•Working temperature of -40°C ~ 75 °C, relative humidity
is 5% ~ 95%
6.3 Installation
This section describes how to install the Gigabit PoE switch
and make connections to it, please read the following topics,
and perform the procedures in the order being presented.
DIN-rail mounting
Adopt the 45mm standard DIN card rail type installation,
check whether the DIN-rail rail mounting tool accessories
(this product has supplied installation fittings) check whether
the DIN rail is firm.

7
The DIN card into the DIN rail connector, check and confirm the
product reliable installation to DIN rail.
7Connecting the PoE Splitter
You can use 60W PoE Splitter with PSE to expand your
network to where there are no power lines or outlets, where
you wish to fix devices such as APs, IP Cameras, or IP Phones,
etc. The following steps will tell you how to connect the PoE
Splitter correctly.
1. Use a UTP cable to connect a PoE port of the PSE
(ex. PoE Switch) to the PoE port.
2. Connect the Data port to the Ethernet device with
UTP cable for data transmitting.
3. Connect the DC(Vout1) port to the power port of
the same Ethernet device with the provided power cable.
