Hardware Installation and Reference Guide
Installing an Ethernet Port Arrester
Note

The Ethernet port arrester is only for the 10/100 Mbps electrical ports with an RJ-45
connector.

The Ethernet port arrester is not delivered with the switch. Please purchase it as required.
The Ethernet port arrester user manual contains technical parameters and maintenance
and installation instructions for the Ethernet port arrester. Carefully read this manual
before installation.
Caution is needed to avoid the following cases:

Reversed installation direction of the arrester. Connect the external network cable to the IN
end and connect the Ethernet port of the switch to the OUT end.

Poor grounding of the arrester. The grounding wire of the arrester should be as short as
possible to ensure that it is in good contact with the grounding terminal of the switch. Use a
multimeter to confirm the contact condition after grounding.

Incomplete arrester installation. If there is more than one port connected to external power
cords, arresters need to be installed on all connection ports for the purpose of surge
protection.
