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.

CAUTION
When connecting IEEE802.3bt compatible devices to this device, AWG24 and
65 °C or higher rated temperature cables are recommended.
If cables other than the above are used, that may cause overheating, ignition, or
malfunctions.
It is strongly recommended that a lightning arrester (SPD) be installed on the
twisted pair port side and the power supply side of this Ethernet Switch.
Malfunctions might be caused from overcurrent and overvoltage due to the
effects of lightning strikes.
