Power over Ethernet (PoE) – Demystifying Mode A and Mode B
Power over Ethernet (PoE) can transmit power up to 100 meters. These long cables are easier to deploy than electrical cabling in locations where power is absent. Because PoE relays relatively low amounts of power, the technology presents low risks of electrical hazards.
When installing a Powered Device (PD) with a PoE-enabled Power Sourcing Equipment (PSE), it is important to take note that
