Important Requests on Protection from Lightning Strike
 If you connect a network camera, a wireless access point, or other devices that can be
affected by a lightning strike (in particular, devices installed outdoors) to the twisted pair
port of this Ethernet Switch, a lightning surge current/voltage may be conducted to this
Ethernet Switch through the twisted pair cable, leading to malfunction. If you connect such a
device, it is strongly recommended that you install a surge protective device (SPD) on the
twisted pair port side of this Ethernet Switch.
 A lightning surge current/voltage may be conducted to this Ethernet Switch through the
power supply or ground wire connected to the power port, leading to malfunction. If a
lightning surge current/voltage may flow in through the power supply or ground wire, it is
recommended that you install a surge protective device (SPD) on the power port side of this
Ethernet Switch.
