Abstract: A method includes a controller detecting a signal state of a presence terminal that is associated with a bus device. The signal state is set by the bus device to indicate presence of the bus device in a connector, and the connector is connected to a bus. The method includes the controller communicating data over the bus; and in response to detecting the signal state, the controller communicating side channel data to the bus device to authenticate the data that is communicated over the bus as being provided by the controller. Communicating the side channel data with the bus device includes providing a signal to the presence terminal, which represents the side channel data.

Abstract: An example device may include processing circuitry and a management controller. The processing circuitry may include a communications interface that includes a first register and a second register. The first register may include a freshness bit and a number of first data bits. The second register may include a number of second data bits that correspond, respectively, to the first data bits. The processing circuitry may write variously to the first data bits in response to detected events, set the freshness bit in response to the management controller reading the first data bits, and reset the freshness bit if any of the first data bits are written to. The management controller may read the first data bits, perform predetermined processing based thereon, write to the second data bits based on the predetermined processing, and request a register transfer.

Abstract: A technique includes providing a communication path in a network switch for communication of data between a first device coupled to the switch and a second device coupled to the network switch. The technique includes using the network switch to regulate tagging of the data to control a virtual local area network identity association of the data based at least in part on a network over which the communication occurs.

Abstract: Systems and methods for updating at least one field replaceable unit (FRU) are disclosed. In an exemplary embodiment the method may comprise generating a virtual image of a FRU ID for each FRU to be updated. The method may also comprise storing the virtual image separate from the FRU ID. The method may also comprise providing a handle to the virtual image so that updated information is retrieved from the virtual image when the FRU is accessed.
