  • Patent number: 11099620
    Abstract: A fail-safe power limit (FSPL) can be applied to components that lose communication with a management module (MM) to determine a safe power level at which to operate. The FSPL may be computed by the management module (MM) for the information handling system and distributed to components in the information handling system. By computing a FSPL and transmitting the FSPL to the components, a larger amount of the available power can be used by the components. This allows the components to continue operating at performance levels closer to or equivalent to levels available when the management module (MM) is operating normally. The FSPL may be updated at set times and/or on a periodic schedule such that the FSPL used by the components when communication is lost with the management module (MM) reflects a recent operating state of the components.

  • Patent number: 10893626
    Abstract: An information handling system includes multiple power supply units, and first and second chassis management controllers. The power supply units provide power to components within the information handling system. The first chassis management controller calculates a first number of power supply units needed to provide power to the components of the information handling system, and asserts a first chassis armed signal to servers in response to a detection that the first number of power supply units is greater than zero. The second chassis management controller receives the first number of power supply units from the first chassis management controller, and asserts a second chassis armed signal to the servers in response to a detection that the first number of power supply units being greater than zero.

  • Patent number: 10353453
    Abstract: A controller may be communicatively coupled to a power supply and may be configured to receive a status signal indicative of whether a level of power delivered by the power supply exceeds a threshold power level. The controller may also be configured to, in response to the status signal indicating the level of power delivered by the power supply exceeds the threshold power level, cause a module power limit of at least one of a plurality of modules disposed in a chassis to decrease, wherein the module power limit of a module defines a maximum amount of power the module may consume from the power supply. The controller may also be configured to, in response to the status signal indicating the level of power delivered by the power supply does not exceed the threshold power level, cause the module power limit to increase.

  • Patent number: 9207165
    Abstract: The present invention relates to a sample chamber for laser ablation analysis of fluid inclusions, comprising a sample cell having a sample cell through-hole extending along the vertical direction and a sample channel extending through the sample cell in a direction transverse to the vertical direction and communicating with the sample cell through-hole. A transparent element is arranged on each of the top and bottom sides of the sample cell through-hole, and is fixed to the sample cell through a fixing ring. The sample chamber further comprises a base comprising a viewing hole and a receiving portion for receiving the sample cell, wherein the viewing hole is coaxially aligned with the sample cell through-hole when the sample cell is placed within the receiving portion. According to the sample chamber of the present invention, it is only necessary to change the sample cell during replacement of the sample chamber, which leads to a convenient operation.
