Lightning Protection

Installing AC Power Arrester (Lightning Protection Power Strip)
The AC power port must be connected to an external lightning protection power strip to prevent the switch from
being struck by lightning when the AC power cord is introduced from the outdoor and directly connected to the
power port of the switch. The lightning protection power strip can be fixed on the cabinet, workbench, or wall in
the equipment room by using cable ties and screws. AC power enters the lightening protection power strip and
then gets to the switch.
