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.

    before the XMODEM started sending the file, an error occured, it says

    “transfer cancelled by remote computer”

    Is there any settings needed to be tweaked?

    Not that I remember make sure you are using the 115200bps speed for the download. Are you trying to do it from the rommon? Here are couple of other links explaining the process in detail:
