Swtich is working condition. (POST test passed)


I could reset my 2 switches, but other 2 switch coudln't.


I held "Mode" button until fa0/1 light is off. it goes to below section (swtich:)


The problem is this switch was treaked because flash:config.text flash:config.text.old      (flash command doesn't work, i can't even see command list from help command)


I did lilke this


- go to (switch:) mode (holding mode button until fa0/1 is off)

- flash_init (it works)

- dir flash:


If you have any idea, it will be appreciated.

5    -rwx  2740      <date>               config.text 


  - I can't delete or rename config.text because of permission.

  - normal password reset method doesn't work  (flash:config.text)   I guess previous owner of switch, he treaked this.

These devices are very limited when in Rommon mode.  You are typing "rename config.text config.old"  and "delete config.text."  I have never know this syntax to work when in Rommon.  Because the switch has no idea where to find the file, it gives you an unhelpful error message.  Try using "rename flash:config.text flash:config.old"  if you want to keep the old configs for some reason, or if you don't try "delete flash:config.text."


Hope this helps,

Rob
