Problems solved by technology

[0005] The disadvantage of the prior art is that the bridge of the CPU motherboard does not support the hot-swapping of its PCI Express devices, so that the motherboard must be powered off when the expansion board needs to be replaced due to a failure, resulting in the interruption of the entire system business and unnecessary losses.

Embodiment Construction

[0032] The invention provides a hot-swap control device and method, the core idea of ​​which is to realize the hot-swap of PCI Express equipment by adding a hot-swap control module on the CPU main board.

[0033] As shown in Figure 2, a kind of hot-swap control device, its CPU motherboard comprises hot-swap control module, bridge piece and power controller, and described hot-swap control module is connected with described bridge piece and described power controller respectively connected.

[0034] The hot-swappable control module is used to detect whether the expansion board’s insertion stability indication signal is valid and then sends a corresponding interrupt signal. If the expansion board’s insertion stability indication signal is valid, the corresponding interruption signal is a power-on interruption. If the expansion board’s insertion stability indication signal is The indication signal is invalid, and the corresponding interrupt signal is power-off interrupt;

Abstract

A method for controlling online connection-disconnection includes issuing an interruption signal by online connection-disconnection control module, launching command signal to said control module by bridging plate according to interruption signal, retransmitting command signal to power supply controller by said control module and using power supply controller to carry out power control on expansion board. The control device used for realizing said method is also disclosed.

Description

technical field [0001] The present invention relates to hot swap technology, in particular to a hot swap control device and method. Background technique [0002] With the development of demand and the advancement of technology, there are more and more demands for expanding PCI Express (Peripheral Component Interconnect Express, fast peripheral component expansion interface) devices on the bridge chip of the server motherboard to realize the expansion of the system. Such a design can Provide flexible I / O (Input / Output, input and output) device expansion. However, the existing bridges do not all support hot plugging of PCI Express devices, and hot plugging of devices is a basic requirement for telecommunications equipment, so this shortcoming has become a bottleneck of telecommunications technology in the application of telecommunications technology . [0003] As shown in Figure 1, the expansion board is a PCI Express device on the CPU main board, which can realize the expan...
