A power over ethernet surge protector, also known as a PoE surge protector (Surge Protective Device), is designed to protect Ethernet-based systems from transient overvoltage caused by lightning
PoE reduces the risk of short circuits, exposed wires, or accidental contact with high-voltage wires that can occur when running separate power
Overvoltages caused by switching or lightning transients can damage PoE-enabled equipment. However, a variety of methods is available for protection.
