Table 2-5. PoE Plus Key Features (Continued) Feature Description Per-Port Power Prioritization Provides the ability to assign a priority to each PoE port. When the power budget of the PoE switch has been exhausted, the higher-priority ports are given preference over the lower-priority ports. Lower priority ports are automatically stopped from supplying power in order to provide power to higher-priority ports. Per-Port Power Limit Configurable power limit for each PoE-Plus port. Power Management Modes Supports three power-management modes: • Static-Reserves a configurable amount of power for a PoE port. • Dynamic-Power is not reserved for the port at any point of time. Power is supplied based upon the detected powered device (PD) signature. • Class-based-Reserves a classed-based amount of power for a PoE port. The final power delivered is determined via LLDP-MED negotiation, which allows for refinement of the power limit. Power Detection Mode Sets the mode to 802.3at or 802.3at+legacy detection. Power Over Ethernet (PoE) Support PoE switches implement the PoE specification (IEEE 802.3af) and support configuration for power threshold, power priority, SNMP traps, and PoE legacy device support. Power can be limited on a per-port basis. PoE Plus Support PoE Plus-capable switches implement the PoE Plus specification (IEEE 802.3at), in addition to the IEEE 802.3af specification. This allows power to be supplied to Class 4 PD devices that require power greater than 15.4 Watts. Each port is capable of delivering up to 30W of power. Real-time power supply status is also available on the switch as part of the PoE Plus implementation. 80 Switch Feature Overview
