Appendix B: Preventing Lightning

To avoid damage during a lightning storm and ensure a stable performance, our router has
adopted the professional lightning protection technology to prevent the lightning. However,
although these measures have been taken to protect TL-R470T+ from lightning, if the lightning
intensity exceeds a certain range, damage to the router may still happen. To protect the router
from lightning better, the following should be considered:
1) Communication cable should be kept indoors as much as possible to reduce the possibility of
equipment damage due to lightning.
2) If the Ethernet cable is designed for use indoors, under normal circumstances, should not be
used outdoors.
3) Ensure the ground point of the socket of AC power supply is well grounded.
4) To enhance the lightning protection capability of the power supply, a lightning arrester could
be installed at the input end of the power supply. Please read the User Manual of the arrester
carefully before installing it.
5) As for the signal line to which the interface modules of TL-R470T+ are connected, such as
LAN's Ethernet cable, ISDN line, telephone line, E1/T1 line, etc, a special lightning arrester
should be installed at the input end of the signal line to enhance the lightning protection
capability. Please read the User Manual of the arrester carefully before installing it.
Note:
The lightning arrester is not provided with our product. If needed, please self supply the arrester
and read the User Manual of the arrester carefully before installing it.
