dn001

  1.拔掉交换机的电源线
  
  2。用超级终端和控制线连到交换机,超级终端的设置是:
  9600 baud rate
  No parity
  8 data bits
  1 stop bit
  No flow control
  
  3。按住交换机前面板的“mode”按钮,插上电源线,当端口1上面的灯不亮后,放松“mode”按钮;
  
  4。这时超级终端上应该显示:
  The system has been interrupted prior to initializing the flash file system.
  The following commands will initialize the flash file system, and finish loading
  the operating system software:
  
  flash_init
  load_helper
  boot
  
  5。输入flash_init
  
  6。输入load_helper
  
  7. 输入dir flash:
  这时显示:
  Directory of flash:
  2 -rwx 843947 Mar 01 1993 00:02:18 C2900XL-h-mz-112.8-SA
  4 drwx 3776 Mar 01 1993 01:23:24 Html
  66 -rwx 130 Jan 01 1970 00:01:19 env_vars
  68 -rwx 1296 Mar 01 1993 06:55:51 config.text
  1728000 bytes total (456704 bytes free)
  
  8。输入rename flash:config.text flash:config.old
  
  9.输入boot,重新启动系统
  
  10。系统启动完后显示:Continue with the configuration dialog? [yes/no] :
  输入N
  
  11.输入enable
  
  12.进入enable模式后,输入rename flash:config.old flash:config.text
  
  13。接着按以下步骤操作:
  
  Switch# copy flash:config.text system:running-config
  Source filename [config.text]? (press Return)
  Destination filename [running-config]? (press Return)
  14 。接着按以下步骤操作:
  switch#configure terminal
  switch(config)#no enable secret
  switch(config)#no enable passWord
  switch(config)#exit
  switch#write memory
  
  这时,系统就恢复没有密码的状态了
