on the right, the polarity of the arrester power cable shall be reversed by the power arrester; if the LED is still
Red, it is confirmed that the arrester PE terminal has not been grounded.
Installing the Ethernet Port Arrester
During the switch usage, the Ethernet port arrester should be connected to the switch to prevent the switch
damage by lightning before the outdoor network cable connects to the switch.
Tools: Cross or straight screwdriver, Multimeter, Diagonal pliers
Installation Steps:
(1) Tear one side of the protective paper for the double-sided adhesive tape and paste the tape to the housing
of the Ethernet port arrester. Tear the other side of the protective paper for the double-sided adhesive tape
and paste the Ethernet port arrester to the switch housing. The paste position for the Ethernet port arrester
should be as close to the ground terminal of the switch as possible.
(2) Based on the distance of the switch grounding terminal, cut the grounding line for the Ethernet port arrester
and firmly tighten the grounding line to the grounding terminal of the switch.
(3) Use the multimeter to check whether the grounding line for the arrester is in good contact with the switch
grounding terminal and the framework.
(4) According to the description on the Ethernet Port Arrester Hardware Installation Guide, connect the arrester
by using an adapter cable (note that the external Ethernet cable is connected to the IN end, while the adapter
cable connected to the switch is connected to the OUT end) and observe whether the LED on the borad is
normal or not.
(5) Use the nylon button to bundle the power cables.

Note
The Ethernet port arrester is only for the 10/100M copper Ethernet ports with the RJ-45 connector;
The Ethernet port arrester is not provided, the user can purchase them to address their own pratical
requirements. For the detailed information for the arrester installation, please refer to Ethenet Port Arrester
Hardware Installation Guide, which contains the technical specification and the maintenance and installation of
the arrester.
Pay attention to the following conditions during the actual installation to avoid affecting the performance of the
Ethernet port arrester:
