Question

嗨，我是解装箱的2x纸箱的C4510RE底盘，并发现这个引导错误，始终出现在两个底盘。

以前有人遇到过这种情况吗？

看上去是个虫子。去找技术支持。

同时，您可以尝试用最小的硬件和软件配置重新启动开关，并查看是什么触发了问题，从而缩小了问题的范围。

(1)硬件:4510 is是一种带线卡的双管底盘。因此，拔出所有的线路卡，拔出冗余电源，拔出多余的监控器，从一个主管开始，看看是否还会发生异常终止。如果是这样的话，你真的别无选择，只能等待支持。如果它启动良好，那么您可以尝试一个一个地插入所有删除的组件。

(2)软件:当启动配置中有一些软件不能正确“消化”时，有时会发生异常终止。Cisco提供了一种通过不读取启动配置(这实际上是密码恢复过程的一部分)来引导设备的方法--您可以尝试此过程，并查看启动配置中是否存在导致问题的内容。

重申:以上只是一个权宜之计，直到你的技术支持发现问题。我个人的看法是，最好是等待支持。
