Abstract: A method for effecting assignment of addresses in a system including at least one server device communicatingly coupled with a plurality of client devices, the addresses permitting communications among the at least one server device and at least one selected client device, includes the steps of: (a) identifying a respective geographic locus for each respective client device; and (b) assigning a respective geographic address for each respective client device; each respective geographic address identifying a particular respective geographic locus for a particular respective client device. A system for effecting communication among a plurality of server devices and a plurality of client devices includes: (a) a communication bus coupling the plurality of server devices; and (b) a plurality of connection loci coupled with the communication bus. Respective client devices are coupled with selected connection loci. Each respective connection locus is uniquely identified by a respective address.

Abstract: An electronic shelf includes a plurality of system circuit boards including a first system circuit board containing a first central processing unit (CPU) providing decision-making intelligence for end-user services supported by the first system circuit board. An auxiliary circuit board is connected to the first circuit board and provides input and output communications between the CPU and devices external to both the first system circuit board and auxiliary circuit board. The CPU is solely responsible for decision-making intelligence for management control for at least a predetermined number of system circuit boards while also being responsible for the decision-making intelligence for end-user services supported by the first system circuit board.

Abstract: One or more programmable clock management components of an apparatus in one example are coupled with a backplane. The one or more programmable clock management components comprise a reconfigurable clock management component. Upon receipt of one or more control signals, the reconfigurable clock management component undergoes a reconfiguration to be able to process one or more frequency signals.

Abstract: An ejector handle mounted to an electronic circuit card provides leverage to assist in engaging and disengaging the electronic circuit card from engagement with an electronic shelf. The ejector handle transmits light, such as by using light pipes, from an end of the handle adjacent to the faceplate of the electronic circuit card to a distal end of the handle where the transmitted light exits for viewing by maintenance personnel. A visual indicator assembly on the electronic circuit card supplies the sources of light that are coupled to and transmitted through the ejector handle. Indicia on the surface of the ejector handle identifies the corresponding function of the lights.

Abstract: Mezzanine boards can be added to and removed from a supporting base board mounted in a slot of a shelf adjacent other base boards while the base boards remain in electrical service. Guide rails allow a mezzanine board to be slid into position from the front edge of the base board. The guide rails themselves can be moved to provide a new spacing to accommodate a different width mezzanine board without having to take the supporting base board out of service. Openings in the sides of the guide rails promote the flow of air between the mezzanine board and the base board to provide cooling.
