Episode 112: Power over Ethernet (PoE and PoE+)

Power over Ethernet (PoE) allows devices like access points, VoIP phones, and security cameras to receive power and data over a single Ethernet cable. In this episode, we explain how PoE and PoE+ work, including power classifications, standards like IEEE 802.3af and 802.3at, and how switches negotiate power with connected devices. You’ll learn how this technology simplifies installations by removing the need for separate power cables and outlets.We also explore power budgets, device compatibility, and how to troubleshoot PoE-related issues such as insufficient wattage, improper cabling, or failed device detection. Whether you're deploying IP surveillance or building a wireless network, PoE is a time-saving and cost-effective solution. This episode prepares you to understand PoE architecture, select the right equipment, and solve common deployment challenges.
