IGURE
3. The grounding system with good ground grid is preferred for
the switch. A lot of residential buildings with proper grounding
have a grounding resistance of 1 ohm. If the test shows that
grounding system is not satisfied, it is recommended to equip
an independent grounding post and the grounding cable must
be 16 mm 2 in diameter and as short as possible. Whichever
grounding method is used, the grounding resistance must be
less than 5 ohm and cannot exceed 10 ohm.
4. It is prohibited that the switch directly gets the power from
the outdoor overhead power cable. If the switch must directly
get the power from the outdoor overhead power cable, spe-
cial lightning protection measures, such as lightning protec-
tion socket and lightning protection bar, must be added to the
power supply. The lightning protection bar for the power sup-
ply must have better lightning protection index than that for
the port cable.
5. Whether the Ethernet switch will suffer lightning strike is af-
fected by a lot of factors, including grounding, power sup-
ply, and wiring. The lightning strike lead-in mechanism also
varies a lot. Taking one measure is far from enough to pre-
vent the lightning strike. Therefore, several measures must
be implemented at the same time. Proper grounding, appro-
priate power supply, reasonable wiring, and suitable lightning
protection measures will definitely reduce the chance of the
switch damage resulted from lighting strike.
