During the switch usage, the Ethernet port arrester shall 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:
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 shall be as close to
the grounding terminal of the switch.
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.
Use the multimeter to check whether the grounding line for the arrester is in good contact with the switch grounding
terminal and the framework.
According to the description on 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 observe whether the LED on the borad is normal or not.
Use the nylon button to bundle the power cables.
