Abstract: Embodiments of the present disclosure provide systems and methods to enable a Power Source Equipment (PSE) and a Powered Device (PD) advertise their identity, capabilities, and neighbors by exchanging IEEE Standard 802.1AB Link Layer Discovery Protocol (LLDP) information in Ethernet frames. Each Ethernet frame contains one or more LLDP Data Units (LLDPDUs) corresponding to a sequence of type-length-value (TLV structure) structures. The PSEs and PDs utilize optional TLV Structures from among the one or more LLDPDUs to advertise their PoE capabilities.

Abstract: A system and method for global power management in a power over Ethernet (PoE) chassis. Power supply status signals indicative of an operating condition of a plurality of power supplies are provided to a plurality of power sourcing equipment (PSE) controller chips in a plurality of blades of a chassis system. Pre-configured combination logic within each of the PSE controller chips converts an indicated operational state of the plurality of power supplies into a powering decision for each of the ports served by the PSE controller chip. Global power management is also effected through the use of scaling factors for the various blades to ensure that the lowest priority powered port (LPPP) in a first blade does not have a lower priority than the highest priority non-powered port (HPNPP) in a second blade.

Abstract: A system and method for dynamic power provisioning for a wireless access point. Various types of power management information (e.g., number of users, connection speed, etc.) can be used in a process for determining a power request/priority for a wireless access point (WAP). The determined power request/priority can then be used in a dynamic allocation process by which the WAP's allocated power budget can seek to match its current power needs.
