Abstract:
Methods and systems for higher power PoE are provided. Embodiments overcome system limitations to PSE power scaling by using an endspan-midspan configuration which allocates power to the PD from both an endspan PSE and a midspan PSE. Embodiments are particularly suitable for deployed PoE systems having limited power supplies and/or ports designed for lower power. Further, embodiments include power management schemes to enable the proposed endspan-midspan configuration to intelligently allocate power between the endspan PSE and the midspan PSE according to required PD power.
