  • Publication number: 20250231364
    Abstract: An optical fiber distribution sub-frame including a base plate, two opposite sides of which are each provided with a mounting point position; a bracket, which is detachably mounted at the mounting point position on any side of the base plate; and an optical fiber channel tray, which is hinged to the bracket. When the bracket is mounted at the mounting point positions on different sides, the optical fiber channel tray is reversed along with the bracket. When the bracket changes position, the optical fiber channel tray connected to the bracket can be reversed together, so that the bracket and the optical fiber channel tray can be replaced from one side of the base plate to the opposite side, and after reversing, the base plate can be replaced from one rotation direction to the other relative to the optical fiber channel tray.

  • Publication number: 20250198871
    Abstract: A reset pressure method includes sending a first signal to a complex programmable logic device (CPLD) by a BMC; sending a second signal to the BMC to reset the BMC by the CPLD when the CPLD receives the first signal; the CPLD detecting whether a third signal appears in the BMC when the BMC is reset. When the CPLD detects the third signal appearing in the BMC, the BMC is determined to have completed the reset and is operating normally. When the CPLD does not detect the third signal in the BMC, the reset pressure testing of the BMC is determined as interrupted. A reset pressure system and a non-transitory storage medium are also disclosed.

  • Publication number: 20250111151
    Abstract: An index is created with split documents to retrieve and augment generation of a response to a natural language request using a generative machine learning model. When a natural language request is received, a search representation is generated and used to retrieve candidate portions of documents from the index. A relevancy ranking is performed to identify relevant portions of documents from the candidates and provide the relevant portions to prompt a generative machine learning model to provide a result for the natural language request.
