Description
Data line surges account for a significant portion of surge-related damage, particularly in scenarios where equipment was presumed protected but exposure points, such as unprotected modem lines, remain vulnerable. Network interface cards (NICs) are especially susceptible, with even moderate voltage spikes posing a risk of damage. As outlined in Ethernet standards (IEEE 802.3), non-AC network electrical hazards encompass several factors: direct contact between network components and power or lightning circuits, accumulation of static charge on cables and components, high-energy transients penetrating the local cabling infrastructure (caused by neighboring cables or lightning strikes within a mile), and potential differences, even between buildings, affecting safety grounds to which network components are connected.
