Installation precautions
The performance of the port lightning protector may be affected in the following cases:
The port lightning protector is installed in reverse direction. Connect the IN end to the outdoor
•
network cable and the OUT end to the network port on the switch.
The port lightning protector is not well grounded. After the connection, use the multimeter to confirm
•
that the ground wire for the protector is as short as possible to ensure its good contact with the
