摘要
在电子技术与通讯产业迅速发展的今天,如何使系统本身在具备较高可靠性能的同时,能够快速应对突发事件。即当设备某一板卡出现异常时,在不影响其它板卡正常工作的前提下,对出现异常的板卡进行维修或更换,这就要求板卡支持在线热插拔功能。本文给出了一种有效的在线热插拔硬件设计方案,并有效解决了热插拔瞬间抖动对系统造成的严重影响。
With the development of electronic technology and communication technology,the system needs to have high reliability,and system can act rapidly when facing emergency.That requires when one card is failed,this card can be repaired or replaced online,and there should be no impact on the function of other card during the maintenance.So the hot plug operation online is required.This article introduces an effective hardware scheme about hot plug online,and gives a solution to solve the impact on the system from the jitter generated during the hot plug operation.
