Another group input-output pin connects.Master control chip 40 is receiving the hot plug request letter triggering hot plug main switch 41
Number time be sent to control each PCIE slot (PCIE slot 20 and PCIE slot 30) hot plug process by hot plug request signal
All CPU (CPU200 and CPU300), Master control chip 40 is when receiving the hot plug request signal of hot plug switch-dividing 33
Hot plug request signal is sent to CPU300, and Master control chip 40 asks letter in the hot plug receiving hot plug switch-dividing 23
Number time hot plug request signal is sent to CPU200.Hot plug main switch can be push-button switch, and hot plug switch-dividing can
Think push-button switch.
In the present embodiment, Master control chip 40 can use CPLD to realize, its effect identify exactly hot plug switch-dividing or
The signal of hot plug main switch, it is then determined that need which CPU the signal received is transmitted to.In order to ensure the transmission of signal
Correctly, having many group input-output pins in Master control chip 40, it is all independent for often organizing, and is independent of each other.When user is to hot plug
When switch-dividing 23 operates, signal just can be transmitted to CPU200, CPU200 and just perform heat according to this signal by Master control chip 40
The control of swapping process.Such as, when signal be hot drawing go out signal time, then by the power remove of PCIE slot 20.When user is to heat
When plug switch-dividing 33 operates, signal just can be transmitted to CPU300, CPU300 and just hold according to this signal by Master control chip 40
The control of row hot plug process.Such as, when signal be hot drawing go out signal time, then by the power remove of PCIE slot 30.Specifically
In enforcement, CPU200 with Host end 21 is connected by I2C bus, CPU300 with Host end 31 is connected by I2C bus.
The IO case that the present embodiment provides, by increasing Master control chip and hot plug main switch, when needs to some or
When certain several PCIE slot carries out hot plug operations, the hot plug switch-dividing that just operation is corresponding, heat can be inserted by Master control chip
The signal pulling out switch-dividing is forwarded to the CPU of correspondence, thus realizes single deck tape-recorder hot plug operations；When whole PCIE slots are carried out by needs
During hot plug operations, just operation hot plug main switch, the signal of whole hot plug switch-dividings can be forwarded to by Master control chip
Corresponding CPU, thus realize FCL hot plug operations.This apparatus function is various, can select according to the actual requirements, when all
When PCIE slot is required to hot plug, then have only to press hot plug main switch so that operating process is simple, convenient, carries
High work efficiency.
Being preferably carried out mode as one, Host end 21 and Host end 31 is PCA9555 and divides control chip.
As a example by Device end 22, being preferably carried out mode as one, Device end 22 also includes: on and off switch 24,
Many groups input-output pin in Master control chip 40 includes on and off switch pin, and PCA9555 divides control chip to include and power supply
The pin that switch pin is corresponding, the control end of on and off switch 24 is connected with on and off switch pin, the first end of on and off switch 24 with
Power supply connects, and the second end of on and off switch 24 is connected with PCIE slot 21.
On and off switch 24 is controlled by CPU200, connects CPU200 and the connection of power supply or disconnection according to the control of CPU200
CPU200 and the connection of power supply.
As a example by Device end 22, being preferably carried out mode as one, Device end 22 also includes: power supply indicator
25, many group input-output pins also include power supply indicator pin, and PCA9555 divides control chip also to include and power supply indicator
The pin that pin is corresponding, the control end of power supply indicator 25 is connected with power supply indicator pin, the other end of power supply indicator 25
It is connected with power supply.
