Draft:PoE Switch

A Power over Ethernet (PoE) switch is a type of network switch that supplies both power and data to a wide range of network devices connected to the local area network (LAN) through Ethernet cables. This switch, also referred to as power sourcing equipment (PSE) can power devices such as wireless access points, VoIP phones, and IP cameras.

Functionality
PoE switches follow IEEE standards to ensure compatibility and safety. The main IEEE standards are:


 * IEEE 802.3af (PoE): Provides up to 15.4 watts of power per port.
 * IEEE 802.3at (PoE+): Provides up to 30 watts of power per port.
 * IEEE 802.3bt (PoE++): Extends power delivery up to 60 watts (Type 3) and 100 watts (Type 4) per port.

Types

 * 1) Managed PoE Switches: Offer advanced features like VLANs, QoS, and network monitoring, ideal for complex network environments.
 * 2) Unmanaged PoE Switches: Provide basic connectivity without configuration options, suitable for simpler setups.
 * 3) Industrial PoE Switches: Built to withstand harsh environmental conditions, used in industrial and outdoor settings.
