A Power-over-Ethernet (POE) powered device (PD) may be coupled to two power sourcing equipments (PSEs), a PSE and an additional PSE. The PSE may exchange a transport layer protocol communications with the additional PSE. The communications comprising a first communication from the PSE to the additional PSE indicative of a PoE configuration of the PSE and a second communication from the additional PSE to the PSE indicative of a PoE configuration of the additional PSE. The PSE may create a power availability table based on the communications. The PSE may detect occurrence of an event comprising at least one of a change in the power availability table or a change in ability of the PSE to provide power to the PD. On occurrence of the event, the PSE may send additional communications to the additional PSE, requesting to adjust its power allotment for the PD.
