Abstract: Techniques to move high current power distribution layers for integrated circuit core power and serializer-deserializer (SERDES) power into a center area of the integrated circuit footprint. This provides a more reliable and higher current distribution into the center of a large integrated circuit footprint, without causing disruption of high speed signal routing or increased signal integrity burden to the high speed signals. Arrangements and methods for routing out the core power area of a main printed circuit board under an integrated circuit and replacing it with a custom power printed circuit board (power plug) that is attached by a metalized paste sintering process. This provides a more reliable and higher current distribution into the center of a large integrated circuit or other high-power component, without causing disruption of high speed signal routing.

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: Devices, systems, methods, and processes for feature level power calibration are described herein. Network devices include sensors that generate sensor readings indicative of various device parameters. A calibration logic utilizes the sensor readings and feature permutations associated with the sensor readings to predict a feature level power consumption for all features of the network device. The calibration logic then applies a calibration factor to the predicted feature level power consumption and obtains an actual feature level power consumption. Using the actual feature level power consumption, the calibration logic determines an actual power consumption for feature licenses of the network device. The feature and feature license level power consumption is utilized for determining which features or feature licenses can be deactivated when the device power consumption is outside a threshold limit. Such dynamic deactivation ensures that the network device accurately meets the sustainability goals.

Abstract: In one embodiment, an apparatus includes a power supply operable to output power to a load along with at least one other power supply, a sensing component for identifying a load level, and a control component for switching the power supply from a full power mode to a power saving mode based on the identified load level. The power supply shares current with the other power supply at a lower current and generally the same voltage as the other power supply while in the power saving mode.
