Note
●
The Ethernet port arrester is only for the 10M/100M copper ports with an RJ-45 connector.
●
The Ethernet port arrester is not delivered with the switch. Please purchase it based on actual
requirements.
Pay attention to the following conditions during the actual installation to avoid affecting 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 ground cable of the arrester should be as short as possible to ensure
that it is in good contact with the ground terminal of the switch. Use a 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,
arresters need to be installed on all connection ports for the purpose of lightning protection.
