switch with poe
A switch with PoE (Power over Ethernet) represents a revolutionary advancement in network infrastructure, combining traditional switching capabilities with power delivery functionality. This integrated device efficiently manages data transmission while simultaneously providing electrical power to connected devices through standard Ethernet cables. Operating at the data link layer, these switches typically offer multiple ports ranging from 8 to 48, each capable of delivering both network connectivity and power to compatible devices such as IP cameras, VoIP phones, and wireless access points. The PoE technology eliminates the need for separate power cables, significantly simplifying installation and reducing infrastructure costs. Modern PoE switches support various standards including IEEE 802.3af, 802.3at (PoE+), and 802.3bt (PoE++), delivering power outputs from 15.4W to 90W per port. These switches incorporate sophisticated power management systems that protect connected devices from power surges and ensure optimal power distribution across all ports. Additionally, they feature intelligent power scheduling capabilities, allowing administrators to control power delivery based on time schedules or specific conditions, thereby enhancing energy efficiency and reducing operational costs.
