If the signal in place of local terminal master control borad and opposite end master control borad is all normal, determine that opposite end master control borad breaks down.
So, if local terminal master control borad is found the heartbeat signal of opposite end master control borad and is stopped, and the signal in place of finding local terminal master control borad is normal, local terminal master control borad normal operation is described, the signal in place of simultaneously judging opposite end master control borad is also normal, and the heartbeat signal of opposite end master control borad has stopped, illustrating that fault has appearred in opposite end master control borad.Therefore, in this case, local terminal master control borad just can, by sending reset signal to opposite end master control borad, restart opposite end master control borad.

Whether the signal in place of step S406, detection opposite end master control borad is normal; If normal, continue step S407; If undesired, alarm, checks with reminding user whether opposite end master control borad normally inserts corresponding groove position;
If the signal in place of step S407 local terminal master control borad and opposite end master control borad is all normal, determine that opposite end master control borad breaks down.
In step S303, when online and its CPU operation irregularity of the other side being detected, confirm that the other side breaks down, by described reset signal alignment the other side, send reset signal; And when main control board breaks down, slave control board replaces main control board and service interface board to carry out service communication.Concrete, with slave control board, main control board detected and break down as example, as shown in Figure 5, comprising:
Step S501, slave control board 2 send reset signal by reseting signal line 24 to main control board 1, and now the state information updating of main control board 1 is 11;
Step S502, slave control board 2 are 00 by the state information updating of local terminal master control borad, and slave control board 2 confirms that local terminal is new main control board;
Step S503, slave control board 2 output useful signals;
Step S504, service interface board receive useful signal instruction, and indicating services interface board service switchover passage and slave control board 2 carry out service communication.
It should be noted that, the order of step S501 and step S502 can be exchanged, and the opposite end master control borad that can first reset upgrades the state information of local terminal master control borad again, also can first upgrade the state information of local terminal master control borad, rear reset opposite end master control borad.The front and back order of these two steps does not affect the beneficial effects of the utility model.
In addition, if system occurs abnormal, for example, if two master control borads are first level state 00 or second level state 10 at one time, local terminal master control borad is confirming that the second level state information 10 of local terminal master control borad or first order state information 00 upgrade while lagging behind opposite end master control borad, opposite end master control borad is defined as main control board, and the state information of local terminal master control borad forces to be updated to third level state information 01.So, will there will not be two master control borads simultaneously as the situation of main control board, also just there will not be two master control borads simultaneously by the situation of useful signal line output useful signal.
In sum, the above-mentioned network equipment that the utility model embodiment provides, comprise main control board, slave control board and at least one service interface board, described service interface board is connected with slave control board with main control board respectively, between main control board and slave control board, be provided with reseting signal line, wherein: main control board and service interface board carry out service communication; Active/standby master control borad Real-Time Monitoring the other side's running status, when online and its CPU operation irregularity of the other side being detected, confirms that the other side breaks down, and by described reset signal alignment the other side, sends reset signal; And when main control board breaks down, slave control board replaces main control board and service interface board to carry out service communication.Simultaneously, because the former main control board of fault resets, if the current main control board that carries out service communication breaks down, the former main control board having resetted, by replacing main control board and service interface board when prior fault to carry out service communication, can not cause communication disruption while again there is master control borad fault.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
