简介
本文档介绍如何使用控制台恢复IC3000。
如何从控制台恢复IC3000
在某些情况下，IC3000会变得不可启动，并且卡在rommon>中，但无法启动其映像。
在这种情况下，串行/usb控制台可以显示以下输出：
autoboot: Restarting the system. Rom image verified correctly Cisco Systems ROMMON, Version 1.0.0(IC3000), RELEASE SOFTWARE Copyright (c) 1994-2018 by Cisco Systems, Inc. Compiled Thu 09/06/2018 11:38:52.09 by builders Current image running: Boot ROM1 Last reset cause: LocalSoft DIMM Slot 0 : Present Platform IC3000-2C2F-K9 with 8192 Mbytes of main memory MAC Address: 00:00:00:00:00:00 Use BREAK or ESC to interrupt boot. Use SPACE to begin boot immediately.

No kernel found to launch. boot: cannot determine first file name on device "disk0:/" autoboot: All boot attempts have failed. autoboot: Restarting the system.
当您中断启动过程并尝试启动disk0：上的映像时，您可能会看到与上述相同的输出，并且设备基本上处于某种引导循环中。
解决方案
为了恢复IC3000，您需要以下必备条件：
- 到管理端口的IP连接
- TFTP服务器，可通过网络在管理端口上访问
- IC3000映像，可从以下网址下载：https://software.cisco.com/download/home/286321941/type/286322235
- 控制台连接到IC3000上的串行或USB连接
通过这些步骤，您可以将IC3000恢复为可用状态：
- 从上面提供的URL下载IC3000映像，并使其在TFTP服务器上可用
- 连接到IC3000控制台，并在您看到以下消息时按ESC中断启动过程：
Use BREAK or ESC to interrupt boot. Use SPACE to begin boot immediately.
- 中断正常启动序列后，您最终会出现rommon>提示符：
rommon 1 >
- 在管理端口上配置IC3000的IP地址和网关。即使不需要网关，也必须设置一个值：
rommon 1 > address 192.168.100.2 rommon 2 > netmask 255.255.255.0 rommon 3 > gateway 192.168.100.1
- 测试与TFTP服务器的连接：
rommon 4 > ping 192.168.100.1 Sending 10, 32-byte ICMP Echoes to 192.168.100.1 timeout is 4 seconds ?!!!!!!!!! Success rate is 90 percent (9/10)
- 设置要下载的TFTP服务器地址和文件名：
rommon 5 > server 192.168.100.1 rommon 6 > file IC3000-K9-1.0.1.SPA
- 开始下载并从TFTP服务器启动映像：
rommon 7 > tftpdnld ADDRESS: 192.168.100.2 NETMASK: 255.255.255.0 GATEWAY: 192.168.100.1 SERVER: 192.168.100.1 IMAGE: IC3000-K9-1.0.1.SPA MACADDR: 00:00:00:00:00:00 VERBOSITY: Progress RETRY: 40 PKTTIMEOUT: 7200 BLKSIZE: 1460 CHECKSUM: Yes PORT: GbE/0 PHYMODE: Auto Detect Receiving IC3000-K9-1.0.1.SPA from 192.168.100.1!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

成功传输映像后，IC3000将立即从映像启动：
