Abstract: An example electrical connector includes a magnetic core embedded in the overmold and encircling conductive paths therein and a Hall-effect sensor embedded in the overmold and configured to sense a magnetic field of the magnetic core. The Hall-effect sensor generates an output that indicates whether or not the supply current flowing through the connector matches the return current flowing through the connector, and this output may be used to detect stray-current faults in which current bypasses the connector to return via alternative paths such as through a device chassis. The connector may include one or more supply wires embedded in the overmold, one or more return wires embedded in the overmold, one or more supply terminals embedded in the overmold and terminating the supply wires, and one or more return terminals embedded in the overmold and terminating the return wires.

Abstract: Systems and assemblies are provided for exchanged signal routing where the characteristics of an escape route can be modified on a printed circuit board (PCB) in a manner that reduces crosstalk and realizes significant signal quality improvement. Exchanged signal routing techniques involve “exchanging” the signal routing lanes on the PCB, which reduces coupled signal amplitude and phase relationship. Exchanged signal routing techniques can also be applied to other areas on a PCB (e.g., other than escape routes) where space is constrained and other mitigation techniques are not possible. A printed circuit board (PCB) can include an array of contact pads, a plurality of signal lines that include an escape route. One or more exchange junctions disposed within the escape route can route a first signal line of a first routing channel in the escape route into a second routing channel in the escape route.

Abstract: Disclosed techniques provide a view and edit function to simultaneously view and edit multiple network device configurations. The techniques may include, parsing a plurality of different network device configuration documents (e.g., files representative of configuration settings). Parsing may then identify a set of slots and anchor points relative to locations of related parameter settings within each of the different network device configuration documents (e.g., a document per device). The slots may indicate a type of parameter setting and the anchor points indicating a relative location within a specific device configuration representative document. As a user makes a change to a parameter value, at least two files of the different network device configuration documents within a scope of an editing session may be identified to receive the change. Reverse mapping may be provided (e.g., by slots and anchor points) to properly implement this change for each different device.

Abstract: Examples described relate to disabling of MAC address aging time for an IoT device on a network switch. In an example, in response to a device joining a network, a network switch in the network may determine a media access control (MAC) address of the device. The network switch may then send the MAC address to an authentication server. In response, the network switch may receive a Vendor Specific Attribute (VSA) associated with the MAC address from the authentication server. The VSA indicates that the MAC address relates to an IoT device. Based on the VSA, the network switch may recognize the MAC address of the device as a MAC address of the IoT device. In response to recognizing, the network switch may disable MAC address aging time for the MAC address of the IoT device on the network switch.
