Important Notice for Measures against Failures
Caused by Lightning Strikes
●When connecting devices (especially outdoor devices) prone to lightning strikes,
such as network cameras or wireless access points, to a twisted pair port of this
Switching Hub, overcurrent and/or overvoltage caused by lightning may affect
this Switching Hub through a twisted pair cable, causing equipment failure.
When connecting such devices, we strongly recommend installing a lightning
arrester (SPD; Surge Protective Device) at the twisted pair port side of the
Switching Hub.
●Overcurrent and/or overvoltage caused by lightning may affect this Switching
Hub through a power source connected to the power port and/or a grounding
line, causing equipment failure. When there is a possibility of overcurrent/over
-
voltage from lightning affecting this Switching Hub from a power source and/or
a grounding line, we strongly recommend installing a lightning arrester (SPD;
Surge Protective Device) at the power port side of the Switching Hub.
●In case this Switching Hub fails due to lightning strikes, repair charges will apply
even during the warranty period.
