With this standardization, PoE quickly gained popularity, as it enabled a reduction in infrastructure costs, simpler installation, greater flexibility, and increased reliability. It also allowed organizations to better optimize power consumption by being able to use the network to control power to. Under normal circumstances, industrial PoE switches are used in harsh environments with extreme conditions and limited resources, such as extremely low or high temperatures. Unlike traditional office Ethernet, Industrial Ethernet is designed to operate in harsh conditions, such as extreme temperatures. Managed PoE switches feature configurable PoE ports with power budgeting, VLAN support, Quality of Service (QoS), link aggregation, and advanced security protocols such as 802. 1X and port-based access control.
