CISCO 3845路由器故障，求助恢复

albert0324

本人有台cisco3845路由器突然故障，表现为无法进入#，也无法引导ios，出现了rommon 1>。按照网络上流行的使用种种方法都失败了：
1、利用xmodem命令实现快速升级IOS，失败！传输完毕后提示Cache error
2、利用Cisco TFTP server 传输ios，失败！ping不通tftp server
3、重新修改配置寄存器的值为 0x2102 ，失败！
再次求助各位达人，还有什么方法可以恢复？

注，这个3845后面貌似有个类似CF卡的东东，不知道是不是这个坏掉了？

应该是吧。

Cache Error Exception

估计是硬件挂了。不过CF卡你可以拿出来放在电脑上用读卡器检测下。没坏就是没坏。

从tftp load IOS试试看
