最近，由于未知原因，我们偶尔重启了一个配电交换机。最近没有进行硬件/软件更改。我们的日志文件没有指出导致事件发生的任何事情。
该系统是一个 6509-E，在活动和备份管理引擎模块上运行软件版本 15.1(1)SY。
该系统有一个在 SSO 中运行的主要和备份管理卡 (SUP720)。系统在 Standby Hot 模式下积极运行，但 Backup RP 从未作为 Active RP 接管，这导致系统完全重新启动。
备份 RP 最终重新启动并以最新配置重新联机，但主管理卡插槽不会启动任何卡。我们用相同的卡型号替换了卡，但没有运气。这些卡都在备用 6509 机箱上进行了测试，所有这些卡都可以正常启动；这消除了卡故障的可能性。
尝试在此机箱上启动卡时，就我们而言：

它不会再进一步了。当我们检查活动 RP 时，它显示卡正在尝试联机但从未完全启动。
