Data line surges make up an overwhelming majority of all surge
induced damages where the equipment was thought to be already
protected but had a back door such as a modem line unprotected.
Network interface cards, in particular, can be destroyed by
relatively mild spikes. According to Ethernet standards (IEEE
802.3), non-AC network electrical hazards include: Direct contact
between components and power or lightning circuits, static charge
buildup on cables and component, high-energy transients coupled
onto the local cabling system (those induced by other cables which
are installed in the general proximity of network cables or
lightning within a mile radius) and potential differences (even
from building to building, between safety grounds to which
components are connected.)
Bulletproof your system from damaging surges! A protection
plan incorporating data line and AC line surge suppression will
bullet-proof your system against the hazards of surges caused by
lightning faults and electro-static discharge.
