本文說明如何使用主控台復原IC3000。
如何從控制檯恢復IC3000
在某些情況下，IC3000會變得不可啟動，並且卡在rommon>中，但無法啟動其映像。
在這種情況下，序列/usb主控台可顯示以下輸出：
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.

當您中斷啟動過程並嘗試啟動映像（存在於disk0：上）時，您可能會看到與上述相同的輸出，並且裝置基本上處於某種引導循環中。
解決方案
為了恢復IC3000，您需要以下先決條件：
- 到管理埠的IP連線
- TFTP伺服器，可通過網路在管理埠上訪問
- IC3000映像，可從以下網址下載：https://software.cisco.com/download/home/286321941/type/286322235
- 控制檯連線到IC3000上的串列或USB連線
通過這些步驟，您可以將IC3000恢復為可用狀態：
- 從上面提供的URL下載IC3000映像，並在TFTP伺服器上使用
- 連線到IC3000控制檯，並在您看到以下消息時按ESC中斷啟動過程：
Use BREAK or ESC to interrupt boot. Use SPACE to begin boot immediately.
- 中斷正常開機順序後，最後會顯示rommon>提示：
rommon 1 >
- 在管理埠上配置IC3000的IP地址和網關。即使不需要網關，也必須設定值：
rommon 1 > address 192.168.100.2 rommon 2 > netmask 255.255.255.0 rommon 3 > gateway 192.168.100.1
- 測試與TFTP伺服器的連線：
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)
- 設定要下載的TFTP伺服器地址和檔名：
rommon 5 > server 192.168.100.1 rommon 6 > file IC3000-K9-1.0.1.SPA
- 開始下載，然後從TFTP伺服器啟動映像：
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!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

映像成功傳輸後，IC3000會立即從映像啟動：
