1. A method comprising:
receiving, at a thermal modeling module, data from a PSE (Power Sourcing Equipment) for cables extending from the PSE to PDs (Powered Devices), the cables being configured to transmit power and data from the PSE to the PDs;
identifying cable adjacencies associated with at least one of the cables based on the data;
determining a wire gauge associated with the at least one of the cables;
calculating, at the thermal modeling module, thermal characteristics for the cables based on the cable adjacencies and the wire gauge; and
performing one or more actions to reduce a risk of unsafe operation at one of the cables when the thermal characteristics for the cables indicate that a thermal rise associated with the one of the cables exceeds a threshold.
