Installation Guide
During the switch usage, the Ethernet port arrester must 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, and diagonal pliers
Installation steps:
(1) Tear one side of the protection paper for the double-sided adhesive tape and paste the tape to the
framework of the Ethernet port arrester. Tear the other side of the protection paper for the double-sided
adhesive tape and paste the Ethernet port arrester to the switch framework. The paste location for the
Ethernet port arrester must be as close to the grounding terminal of the switch.
(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 Ethernet Port Arrester Hardware Installation Guide, connect the arrester using the adapter
cable (note that the external network cable is connected to the end of IN, while the adapter cable connected
to the switch is connected to the end of OUT) and check whether the LED on the board is normal.
(5) Use the nylon button to bundle the power cables.

Caution

The Ethernet port arrester applies to only the 10M/100M electrical Ethernet ports with the RJ45 connector.

The Ethernet port arrester is provided by customers. For more information about arrester installation, refer
to Ethernet Port Arrester Hardware Installation Guide.
To prevent the performance of the Ethernet port arrester from being affected, note the following points:

Reversed direction of the arrester installation: Connect the external network cable to the IN end and connect
the switch Ethernet port to the OUT end.

Poor arrester grounding: The grounding line must be as short as possible to ensure that it is in good contact
