Abstract: In one embodiment, a method generally comprises monitoring real-time electrical data at Power Sourcing Equipment (PSE) transmitting power over a cable to a Powered Device (PD), calculating thermal characteristics for the cable based on the monitored data, and periodically updating the thermal characteristics based on the monitored data. The power comprises multi-phase pulse power, the data comprises voltage and current measured for each phase of the multi-phase pulse power, and the voltage is greater than 60 volts at the PSE.

Abstract: In one embodiment, a method includes receiving at a thermal modeling module, data from a Power Sourcing Equipment device (PSE) for cables extending from the PSE to Powered Devices (PDs), the cables configured to transmit power and data from the PSE to the PDs, calculating at the thermal modeling module, thermal characteristics for the cables based on the data, and identifying a thermal rise above a specified threshold at one of the cables. The data comprises real-time electrical data for the cables. An apparatus and logic are also disclosed herein.
