  • Patent number: 10948951
    Abstract: A card/chassis coupling system includes a chassis defining a chassis housing with a chassis wall defining a card entrance to the chassis housing. The chassis wall engages a securing element on a card to secure it in the chassis housing. A card/chassis release device adjacent the card entrance includes a base in the chassis housing, and a card mover member and securing element release member that are each moveably coupled to the base and to an actuator member extending through the chassis wall. Movement of the actuator member into the chassis housing causes the securing element release member to move relative to the base to engage the securing element on the card and disengage it from the chassis wall, and causes the card mover member to move relative to the base to engage the card and move it through the card entrance and out of the chassis housing.

  • Publication number: 20210072809
    Abstract: A power converter device health check system includes a circuit that connects a power input to a power output, and that includes a first transistor directly coupled to ground and a capacitor in parallel with the first transistor. A controller device is coupled to the circuit and, during boot operations, prevents first power from being provided to the first transistor via the power input, and turns off the first transistor. While preventing the first power from being provided to the first transistor and with the first transistor turned off, the controller device provides second power to a circuit location in the circuit between the first transistor and the capacitor, and then determines whether a charge of the capacitor is below a threshold charge level. If the capacitor is below the threshold charge level, the controller device transmits a power converter warning message.

  • Publication number: 20210064490
    Abstract: A power consumption/power backup-based ride-through system includes a power supply system that is configured to supply power to the one or more components. A power backup device is coupled to the one or more components and the power supply system, and operates to monitor an amount of power provided by the power supply system to the one or more components. Based on the amount of power provided by the power supply system to the one or more components, as well as characteristics of the power backup device in some embodiments, the power backup device determines a ride-through time period for which the power backup device is capable of powering the one or more components. When the power backup device detects a loss of power to the one or more components, it powers the one or more components for the ride-through time period.

  • Patent number: 10936527
    Abstract: Embodiments include expansion cards that provide a specialized capability, such as networking, when coupled to an Information Handling System (IHS). The expansion card embodiments include a printed circuit board (PCB) of a first width and a heat sink located on a top surface of the PCB. The expansion cards also include pins located on a distal end of the PCB, where the pins are received by a connector of the IHS. Embodiments include a button operable for ejecting a latch of the expansion card from a stored position in response to pressing the button. When ejected, the latch remains within the first width of the PCB, thus supporting high-density configurations of expansion cards. The ejected latch is further operable for an administrator to easily pull the expansion card from the IHS. Expansion card embodiments may also include vents that provide pathways for ventilating heated air away from the heat sink.
