摘要
论述了一种热插拔系统的设计方案,该设计方案可以在系统不断电的情况下增加或者去除插卡,而不影响系统的运行。当系统出现故障的时候,可以在不断电的情况下更换模块或者远程升级、备份模块。该系统由主控板、背板、插卡及相应的软件组成,实现了系统的热插拔设计和插卡上可编程逻辑的在线升级、备份等功能。
This paper, describes a design of hot swap without interrupting power supply, add or remove the system. The design scheme can be implemented in the system： card, and does not affect the operation of the system. When the system failure, do not need power off, replace the module or remote upgrade, backup module. The system consists of main control board, backplane board, card, and software. The design of hot swap system, and the card can be online programming logic upgrade, backup and other functions.
