30 Mar 10 Cisco Catalyst 2900 XL – Recovery from Corrupt/Missing IOS

Recently I was working on one of my switches, .Cisco Catalyst 2900 XL and realized that it was running an old version of Cisco IOS. I am not sure what I was thinking but I deleted everything from the flash: folder and rebooted the switch. Well switch came back on but since there was nothing on it, it just booted into the recovery mode. rommon

Thanks to xmodem and hperterm I was able to load the IOS on it and boot it back up. Here is what I had to do:

  • First I used the console cable to connect to the Cisco Catalyst 2900 XL
  • Next I started the Hper Terminal and got into the switch
  • Then I had to run the following command: copy xmodem imagine-name-123.bin
  • When prompted hit Y for Yes
  • Next you have to click on the Transfer on the top and choose Send File
  • From the drop down menu choose XModem, click on Browse and point to the file
  • Now click on Send
  • This whole process takes a while since the upload is happening over a slow console connection
  • To read more details on the process you can check out Cisco’s Website directly.
