III. Installation precautions
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.
The lightning arrester for the network port is not installed completely. If the switch has more than one network ports to
interconnect with other devices via cables outdoor, you should install lightning arresters for all these network ports for
protection.
