Patent number: 11927786Abstract: A device carrier for an information handling system includes a latch, an interface, lights located on a front of the latch, and first and second light pipes. The latch holds the device carrier within the information handling system. The first light pipes are located within the latch, and provide light to the lights located on the front of the latch. The second light pipes are located within the interface and the latch, and provide the light to the first light pipes. The location of the second light pipes enables the same brightness of the light provided to the lights when a long device is inserted within the device carrier as compared to when a short device is inserted within the device carrier.Type: GrantFiled: January 18, 2022Date of Patent: March 12, 2024Assignee: Dell Products L.P.Inventors: Qingqiang Guo, Harris Di Dihuweii, William A.

Patent number: 11337329Abstract: The front of a rack-mounted 2 RU (Rack Unit) chassis includes bays that receive replaceable components, such as storage drives. Two rear slots of such chassis each receive hot-swappable 1 RU servers that couple to a midplane of the chassis. When a server is removed from its slot while the server in the other slot remains operational, the airflow output of the operational server escapes via the empty slot rather than cooling the components in the front-facing bays. Embodiments provide a single-blade air damper that blocks airflow via an empty chassis slot. The single-blade air damper is connected to spring assemblies on both chassis sidewalls. The spring assemblies are maintained in unstable states when servers are installed in both slots of the chassis. Upon a server being removed from a slot, the spring assemblies transition to stable states that position the single-blade air damper to block airflow via the empty slot.Type: GrantFiled: July 13, 2020Date of Patent: May 17, 2022Assignee: Dell Products, L.P.Inventors: Yuxin Chen, Jie Yang, Qingqiang Guo

Patent number: 11297728Abstract: A chassis housing one or more Information Handling Systems (IHSs) includes a bay for coupling hardware components to the chassis, such as rear-facing bay that extends from the chassis midplane to an externally accessible opening. A first hardware component is fastened to a removeable carrier and the carrier is inserted in the bay, with the first hardware component coupling to the midplane. The carrier includes arms that extend to the externally accessible opening. Each arm includes a retractable handle that is used, when in an extended position, to extract the carrier from the bay. A second, removeable hardware component is inserted in the bay, with the second hardware components nested between the arms of the carrier. The carrier handles rotate to a concealed position when the second hardware component is nested in the carrier and the handles rotate to the extended position when the second hardware component is removed.Type: GrantFiled: October 12, 2020Date of Patent: April 5, 2022Assignee: Dell Products, L.P.Inventors: Zhao Wei Shang, Aiqin Liu, Qingqiang Guo, Zhao Chen

Patent number: 11099613Abstract: The front of a rack-mounted 2RU (Rack Unit) chassis includes bays that receive replaceable components, such as storage drives. Two rear slots of such chassis may each receive 1RU servers that couple to a chassis midplane via interposers. Administration of such 2RU chassis is simplified when a 1 RU server can be installed identically in the top or bottom chassis slot. Embodiments provide this capability while avoiding locating interposers along the center of the midplane. A lower guide routes a floating interposer of the server to lower midplane connectors as the server is inserted in the lower slot. An upper guide routes the floating interposer to upper midplane connectors as the server is inserted in the upper slot. The floating interposer moves up and down based vertical travel of guidewheels that protrude from the server and are routed by the guides as the server is inserted in a slot.Type: GrantFiled: July 10, 2020Date of Patent: August 24, 2021Assignee: Dell Products, L.P.Inventors: Yuxin Chen, Sandburg Hu, Xiang Yu, Qingqiang Guo

Patent number: 10936527Abstract: 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.Type: GrantFiled: March 6, 2020Date of Patent: March 2, 2021Assignee: Dell Products, L.P.Inventors: Yuxin Chen, Weidong Zuo, Qingqiang Guo, Gemma Chen, Chen Zhao, Haifang Zhai
