Abstract
A single shelf network system capable of providing expansion to a multiple shelf mode is described. In one embodiment, slots are provided in a single shelf network system that are capable of accepting either I/O cards or expansion cards. When such a single shelf network system is to be operated in a single shelf mode, such slots may be provided with I/O cards to maximize the data transport capability of the single shelf network system. However, to expand the single shelf network system to function as a multiple shelf network system, the slots are provided with expansion cards. The expansion cards serve to couple a control card of the single shelf network system to one or more expansion shelves, thereby allowing the control card to exert control over the one or more expansion shelves. Since a single expansion card can support multiple expansion shelves, the number of slots of the single shelf network system needed to support expansion does not increase as additional expansion shelves are added.
