Electricity, and switching on and shutting down sequence meets the booting end Shi Xiankai extension cabinet, then successively forward until host is switched on；It is first closed when shutdown
Host, then successively by closely closing extension cabinet to remote.
As shown in Fig. 2, a host connects two-stage extension cabinet, working principle:
Start process:
1, when host and extension cabinet have external power supply input, but are off-mode, corresponding 4 state of module are as follows:
There is supply input, but powering on detection signal is low level, is judged as off-mode；Module 5 export local system in place and on
Electricity condition is in place but does not power on
2, when people is switched on by host front control board switching on and shutting down key, 2 POWER SW of module can receive signal, simultaneously
According to the current off-mode that module 4 determines, decision-making system booting is intended to
3, after central control chip determines that system boot is intended to, preferentially whether there can be next stage extension by the acquisition of module 6
Whether cabinet and extension cabinet power on.It can detect that there are the 1st grade of extension cabinets herein, and the 1st grade of extension cabinet does not power on.Then by opening
Off signal issues starting-up signal to the 1st grade of extension cabinet.Then persistently the power-up state of the 1st grade of extension cabinet is detected
4, when the 1st grade of extension cabinet module 5 receives switching on and shutting down signal, signal processing is identical as main cabinet, and meeting preferentially will
Starting-up signal passes to the 2nd grade of extension cabinet, and persistently detects to the power-up state of the 2nd grade of extension cabinet
5, after the 2nd grade of extension cabinet module 5 receives starting-up signal, confirmed currently by module 4 for off-mode, determine system
System is intended to be switched on.Then the presence of next stage extension cabinet is not got by module 6, then passes through module 3 to the machine control panel
Starting-up signal is sent, the 2nd grade of extension cabinet realizes booting
6, the 1st grade of extension cabinet detects the 2nd grade of extension cabinet and has powered on, then is sent by native module 3 to the machine control panel
Starting-up signal, the 1st grade of extension cabinet realize booting
7, host detects the 1st grade of extension cabinet and has powered on, then sends booting letter to the machine control panel by native module 3
Number, host realizes booting
The above process, realize host cascade extension cabinet system successively powers on booting, i.e., first opens extension cabinet and open host again.
Shutdown process:
1, when host and extension cabinet are open state, corresponding 4 state of module are as follows: have supply input, power on detecting
Signal is high level, is judged as open state；The in place and power-up state that module 5 exports local system is in place and has powered on
2, when people is switched on by host front control board switching on and shutting down key, 2 POWER SW of module can receive signal, simultaneously
According to the current open state that module 4 determines, decision-making system is intended to shutdown
3, after central control chip determines that system closedown is intended to, it can be sent and be shut down to the machine control panel by native module 3
Signal, then continues through whether 4 detecting system of module is turned off.It is to be detected be turned off to system after, pass through module 6 to the 1st
Grade extension cabinet sends off signal
4, when the 1st grade of extension cabinet module 5 receives off signal, signal processing is identical as main cabinet, can first control this
Then organ's machine sends off signal to next stage after detecting this system and closing
5, identical as the 1st grade of extension cabinet signal processing after the 2nd grade of extension cabinet module 5 receives off signal, it can be first
Control the machine shutdown.Then the presence of next stage extension cabinet is not got by module 6, then shutdown process terminates
The above process realizes the successively shutdown of host cascade extension cabinet system, i.e., first closes host and close extension cabinet again.
