Abstract: An information handling system has a regulator, a power indication network, a PSU, and a BMC. The regulator receives a system power level indication and provides power to a processor based upon the power indication. The power indication network includes a first resistor stage to shunt the power indication to a ground plane, and a second resistor stage selectably to shunt the power indication to the ground plane. The PSU provides the power indication as a current output where a level of current output indicates a power level provided by the PSU. The BMC determines a power budget for the information handling system, calculates a number of resistor stages to couple to the ground plane based on the power budget, when the number is less than or equal to one, selects the second resistor stage to be uncoupled from the ground plane, and when the number is greater than one, to select the second resistor stage to be coupled to the ground plane.

Abstract: An information handling system has a chassis having an embedded controller (EC) and a plurality of sleds, each having a BMC. Each BMC 1) determines a configuration of the sled, 2) matches the configuration to an entry of sled thermal characteristics table in the EC, 3) determines whether a maximum ambient temperature field has a first maximum ambient temperature value or an indication to calculate another maximum ambient temperature value, 4) when the maximum ambient temperature field has the first maximum ambient temperature value, ascribe the first maximum ambient temperature value to the operation of the sled, and, 5) when the maximum ambient temperature field has the indication, to a) receive an available airflow value from the EC, b) determine a second maximum ambient temperature value based upon the available airflow, and c) ascribe the second maximum ambient temperature value to the operation of the sled.
