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.
