  • Publication number: 20190027422
    Abstract: A heat sink mounting configuration is provided that is configured to prevent the heat sink from damaging ball grid arrays (BGA) of an application specific integrated circuit (ASIC) mounted on a printed circuit board (PCB) when the line card is subjected to vibrations and shocks. The heat sink mounting configuration may include a set of screws configured to be at least partially disposed within the apertures of the heat sink to secure the heat sink to the PCB. The mounting configuration includes a resilient member and a spacer disposed around the screws proximate to the apertures. The resilient members are configured to bias the heat sink against the ASIC to maintain the heat sink in contact with the ASIC. The spacers are configured to prevent the heat sink from impacting the ASIC with forces large enough to damage the BGA when the line card is subjected to vibrations and shocks.

  • Patent number: 10186823
    Abstract: According to one aspect, an apparatus includes an expansion element, an expandable element, and a frame. The expandable element is configured to have an expanded state and an unexpanded state, wherein the expandable element is arranged to be inserted between a mated pair of printed circuit boards (PCBs) while in the unexpanded state. The expansion element is arranged to cause the expandable element to expand to the expanded state. When the expandable element is in the expanded state, the expandable element causes the pair of PCBs to demate. The frame is arranged to facilitate an insertion of the expandable element between the mated pair of PCBs. In one embodiment, the expandable element is an inflatable element and the expansion element is an inflator element that includes an air supply.

  • Publication number: 20190008066
    Abstract: In one embodiment, a method includes receiving an indication at a modular electronic system of initiation of online removal for a module removably inserted into a slot of the modular electronic system, increasing a fan speed at the modular electronic system before the module is removed, monitoring an internal temperature at the modular electronic system, and providing an indication that the module is ready for removal upon reaching a specified cooling state at the modular electronic system based on the temperature monitoring. A panel on an adjacent module is opened and extends into the slot upon removal of the module to substantially block airflow bypass from the slot and maintain cooling within the modular electronic system. An apparatus and logic are also disclosed herein.

  • Publication number: 20180074136
    Abstract: To reduce the rate at which a false alternating current (“AC”) loss alarming signal is generated, but at the same time detect an actual AC loss situation in a timely manner, the disclosed method describes an AC line power loss detection and active verification method. If the AC line input voltage dips momentarily lower than a standard sine wave amplitude, the AC line may not be considered lost as long as it still has energy to drive a load. The method inserts a momentary load across the AC line and compares the AC line voltage before and after the extra load is applied. If the AC power is present, this extra loading will increase the AC loading current momentarily, but will not affect the AC line voltage. However, if the AC power is lost, such loading will lower the AC line voltage, indicating a loss of power.

  • Patent number: 9894795
    Abstract: According to one aspect, an apparatus includes a body and a toggle-interlock assembly. The body has an opening defined therein. The toggle-interlock assembly is coupled to the body, and includes a toggle portion and an interlock portion. The toggle-interlock assembly has a first configuration and a second configuration. When the toggle-interlock assembly is in a first configuration, the toggle portion physically blocks at least part of the opening while the interlock portion is stowed. When the toggle-interlock assembly is in a second configuration, the toggle portion does not physically block access to the opening while the interlock portion is in a deployed position that is arranged to prevent the apparatus from being inserted into a chassis.
