A kind of dual master control backboard that relatively extensively exists is the dual star topology structure now, as shown in Figure 2.Double star-type system has two main control cards and polylith interface card, between every main control card and every interface card a lane interconnect is arranged all, be used for interaction data, interconnecting channel generally adopts high speed SerDes (Serial and Deserial, string signal is conciliate in serial), be generally high-speed differential signal, one receives one connects two chips, and many high speed SerDes signal interconnections are arranged between each main control card and interface card.
In order to realize that one of them master control draw-in groove position can insert interface card when not inserting main control card, this master control draw-in groove position also needs to place the interface card connector on backboard.Fig. 3 is an example with 5 groove position dual star topology backboards, back panel connector adopts away 2 * 10 couples of ZD (high-speed differential signal) connector of high speed signal, the solid line double arrowed line is represented the interconnecting channel of main control card 1 and interface card 1,2,3, and the dashed double line is represented the interconnecting channel of main control card 2 and interface card 1,2,3.Each interconnecting channel is 10 pairs of SerDes signal interconnections, and each interconnecting channel signal just in time takies a ZD connector.The ZD connector on the right, main control card 2 groove positions is the interface card connector among Fig. 3, and when interface card was inserted in this groove position, interface card can be by the main control card connector interconnection of this connector and main control card 1 groove position.
Fig. 4 a is depicted as the main control card 1 groove position schematic diagram on the main control card insertion backboard, four main control card connectors are arranged on the main control card, on the main control card 1 groove position of backboard four main control card connectors are arranged, corresponding with the connector position on the main control card, when main control card inserted backboard, the main control card connector on main control card and the backboard engaged fully.Schematic diagram when Fig. 4 b is depicted as main control card and inserts main control card 2 groove positions on the backboard, four main control card connectors are arranged on the main control card, on the main control card 2 groove positions of backboard 3 main control card connectors are arranged, 1 interface card connector, for fear of mispluging, interface card connector and main control card connector at interval should be greater than two connectors.Fig. 5 a is depicted as interface card and inserts main control card 2/ interface card 0 groove position on the backboard, and the outside interface card connector on the interface card engages fully with interface card connector on the main control card 2/ interface card 0 groove position; Situation when Fig. 5 b is depicted as interface card and inserts interface card 1,2,3 groove positions on the backboard, two interface card connectors on the interface card respectively with interface card 1,2,3 groove positions on the interface card connector engage fully.
