Patent number: 9066449Abstract: An enclosure has a perforated front door with a replaceable filter, and a perforated rear side allowing air to flow through the enclosure. The enclosure also has mounting brackets for heat generating elements, such as line cards or other rack mounted electronics. A fan draws air through the perforated front door, though the filter, and across the heat generating elements. Side brushes are disposed on a side wall near the front of the enclosure, which allow any cables attached to the heat generating elements to exit the enclosure. The front door is removable, opening up one side of the side brushes and allowing the cables to slide in the side brushes while still connected to the heat generating elements.Type: GrantFiled: August 15, 2013Date of Patent: June 23, 2015Assignee: Cisco Technology, Inc.Inventors: Frank S.

Patent number: 8611103Abstract: A latching apparatus provides selective injection and ejection of an electronic module relative to a chassis that includes a support member. The apparatus includes a housing to be coupled to the electronic module, and a handle pivotably coupled to the housing and movable between a latched position and an unlatched position. A catch in a first position retains the handle in the latched position. An actuator is coupled to the handle and operable to move the catch to a second position. In response to movement of the actuator in a direction the same as the direction of the handle toward the unlatched position, the catch is moved to its second position. As a result, the handle is movable between the latched and unlatched positions to permit the electronic module to be injected or ejected relative to the chassis.Type: GrantFiled: October 27, 2011Date of Patent: December 17, 2013Assignee: Cisco Technology, Inc.Inventors: Sean Thomas, Saeed Seyed, Hong Tran Huynh, Phillip S. Ting, Toan Nguyen

Publication number: 20130130528Abstract: A dual-cam ejector assembly for a card, such as a line card, is provided. The ejector assembly comprises an elongated ejector arm having its distal end coupled to the line card so as to provide a first axis of rotation for the ejector arm. The ejector assembly further comprises an ejector cam coupled to the line card so as to provide a second axis of rotation for the ejector cam. The ejector assembly also comprises a cam pin extending from the ejector cam that couples the ejector cam to the ejector arm such that pivoting of the ejector arm around the first axis of rotation causes the ejector cam to pivot around the second axis of rotation.Type: ApplicationFiled: November 22, 2011Publication date: May 23, 2013Applicant: CISCO TECHNOLOGY, INC.Inventors: Frank S.

Patent number: 8270171Abstract: To increase air flow, an air intake/outtake (i.e., intake, outtake, or both) is positioned on a front surface of a housing, such as a rack-mounted computer network switch housing. The front surface includes jacks, controls, plugs, receptacles or other input/output for connection with the processor in the housing. The air intake/outtake is one or more openings on the front surface with the input/output components. In one embodiment, to avoid interference with the input/output components and increasing the height of the housing, the air intake/outtake is a slot extending most of or all of the distance between the sides of the housing and being above or below the input/output. An intermediate plate may be used to form and support the air intake/outtake.Type: GrantFiled: May 25, 2010Date of Patent: September 18, 2012Assignee: Cisco Technology, Inc.Inventors: Susheela Nanjunda Rao Narasimhan, Hong Tran Huynh, Toan Nguyen, Duong Cu Lu, Phillip S.
