Abstract
A switch fabric system comprises a first chassis for receiving a plurality of line cards each having a plurality of ports and at least two switch fabric cards wherein each line card comprises a plurality of link ports for linking the line card with the switch fabric card. Each switch fabric card provides a switching bandwidth. The system comprises a management unit for managing the traffic on the switch fabric cards wherein the management unit removes the traffic from one switch fabric card if the one switch fabric card is to be removed while the other switch fabric card operates and transfers the traffic to the other switch fabric card.
