Publication number: 20240168528Abstract: An information handling system bay accepts plural communication carriers having storage communication support, such as in compliance with OCP3.0. The communication carrier has a support structure to support processing components, such as a network interface controller coupled to a printed circuit board, and coupled within the bay by a latch having a member extending from one end to engage the bay housing and latching an opposite chamfered end with a pin coupled to a spring loaded button. A press on the button away from the latch releases the chamfered end from the pin so support structure member is free from the housing bay to remove the communication carrier.Type: ApplicationFiled: November 18, 2022Publication date: May 23, 2024Applicant: Dell Products L.P.Inventors: Zhao Chen, Harris Di, John C.

Patent number: 7907537Abstract: A system and method for electronically identifying connections established through a cross-connect system provides for identification of all hard-wired and temporary patch connections, and any modifications made to same. Connection identification and status information is acquired in near real-time and stored in a database which is accessible by a user through a graphical user interface (GUI). The TRACE or lamp wires which connect respective pairs of cross-connect circuits are utilized in an unconventional manner so as to form a scanning bus. The information signal paths established through the cross-connect circuits remain undisturbed. A scanning signal is communicated between each pair of cross-connected circuits over the TRACE conductor. In the event a patch cord is used to temporarily redirect a signal connection, the scanning signal is transmitted over the shield or sleeve conductor of the patch cord. The scanning signal provides identification and other information concerning the transmitting circuit.Type: GrantFiled: March 5, 2009Date of Patent: March 15, 2011Assignee: ADC Telecommunications, Inc.Inventors: Robert J.

Patent number: 6449768Abstract: A switch apparatus is used in the transmission of a redundant Cable TV (CTV) signal. The redundant CTV signal can be a symmetric split linked redundant CTV signal or an asymmetric split linked redundant CTV signal. The switch apparatus is capable of handling both the symmetric and asymmetric redundant CTV signal where primary channels are split into multiple parts. The asymmetrical splitting of the primary channels is where one part contains more channels than another part. The switch apparatus includes a plurality of switches and a monitor device to detect a failure in the split signal path before the split signals are combined to be transmitted to downstream end-users. Upon detecting a failure, the switches are switched from primary channels to secondary channels by a controller. After the signal is returned, the switches are switched back to the primary channels. A delay timer may be included in the switch apparatus to avoid incidental or temporary signal recovery.Type: GrantFiled: April 28, 1999Date of Patent: September 10, 2002Assignee: ADC Telecommunications, Inc.Inventors: Rick Oftedahl, Jeffrey O.

Patent number: 5963843Abstract: An amplifier switch controller is provided for use in a headend cable transmission system having first and second amplifiers and amplifier input and output paths connected to one of the first and second amplifiers, which becomes the currently activated amplifier. The amplifier switch controller comprises an input sampler for sampling a combined signal on the input signal path and measuring an input signal level. The amplifier switch controller also comprises an output sampler for sampling the amplified combined signal on the output signal path and measuring an output signal level. A program means receives the input and output signal levels and determines whether the currently activated amplifier is not functioning properly. If it is not functioning properly, the program means generates a control signal to a switch.Type: GrantFiled: December 9, 1996Date of Patent: October 5, 1999Assignee: ADC Telecommunications, Inc.Inventors: Eric K.
