Fully consider the following items in the installation process,
otherwise, the performance of the lightning arrester for network port
will be affected:
Lightning arrester for network port is installed in reverse direction.
In practice, the "IN" end should be connected to the outdoor network
cable and the "OUT" end to the network port on the switch.
Lightning arrester for the network port is not well grounded. The
ground wire for the arrester should be as short as possible, so to
ensure its good contact with the grounding screw of the switch. After
the connection, use the multimeter to confirm that.
