Problems solved by technology

However, when the expansion card is pulled out and then reinserted, the expansion card can only be restored to its original state, that is, the state just like a newly inserted state, but cannot be restored to the state before the removal, so there is a problem of poor recovery
[0005] To sum up, it can be seen that there has been a problem of poor recovery of hot swapping in the prior art for a long time, so it is necessary to propose improved technical means to solve this problem

Abstract

A hot plugging system and method are disclosed, in which a pluggable device transmits a request to a host before the pluggable device is pulled out so that the host may select whether preserving a device status, and preserves the device status and then shuts down a power of the pluggable device directly when preserving is selected while shuts down directly the power of the pluggable device when no preserving is selected so that the pluggable device is selected to be recovered or initialized according to the device status, existing or non-existing, after being inserted onto the host again, whereby achieving in a technical efficacy of promoting the hot plugging recovery.

Description

technical field [0001] The present invention relates to a hot-swap system and method thereof, in particular to a hot-swap system with recovery capability and its method. Background technique [0002] In recent years, with the popularization and vigorous development of semiconductors, the functions required by users are more diverse. Therefore, using expansion cards to meet various needs of users has become one of the means for manufacturers to solve problems. [0003] Generally speaking, the expansion card is connected to the bus of the motherboard through a slot (Slot) to provide additional functions for the motherboard, such as network, audio, TV, disk control and other functions. Taking the bus standard as an example, it includes: Standard structure (Industry Standard Architecture, ISA), peripheral component interconnection (Peripheral Component Interconnect, PCI) and so on. However, when the mainboard is continuously powered, the action of plugging and unplugging the ex...
