Ethenet Port Arrester Hardware Installation Guide, which contains the technical specification and
the maintenance and installation of the arrester.
You may pay attention to the following conditions during the actual installation to avoid influencing the
performance of the Ethernet port arrester:
Reversed direction of the arrester installation. You shall connect the external network cable to the
“IN” end and connect the switch Ethernet port to the “OUT” end.
Poor arrester grounding. The length of the grounding line should be as short as possible to ensure
that it is in good contact with the switch grounding terminal. Use the multimeter to confirm the contact
condition after the grounding.
Incomplete arrester installation. If there is more than one port connected to the peer device on the
switch, it needs to install the arresters on all connection ports for the purpose of the lightning protection.
