Installation Guide

The Ethernet port arrester is not delivered with the switch. Please purchase it based on actual
requirements. 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.
Pay attention to the following situations during the installation to avoid influencing the performance of the
Ethernet port arrester:
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 cable 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 the peer device on the switch,
arresters need to be installed on all connection ports for the purpose of lightning protection.
