Factory reset AIR-CAP3502I-E-K9

To factory reset a Cisco AIR-CAP3502I-E-K9, follow the following. I’m fairly certain this will work with most Aironet access points but I only have this model available.

  • Connect to the access point with a serial/console cable, fire up PuTTY and connect to the correct COM port.
  • Whilst holding the MODE button, connect the power cable or ethernet cable if using PoE.
  • Keep holdings the MODE button until the LED flashes red. You should see the ap: prompt.
  • Run dir flash: – You should see private-multiple-fs and env_vars
  • Run the following 2 commands
  • Run dir flash: again to confirm the files have been renamed.
  • If everything looks good, type reset and confirm with y to reboot the access point.
  • When the access points reboot, you should be able to login with username: Cisco and password: Cisco

    1. Sorry, it should be env_vars (although it doesn’t really matter what the file is renamed too). Updated the article

  1. What gets done with the -old files? can they be deleted?
    Do they get re-created after device is configured?
    I need to make sure that these devices are thoroughly wiped and cannot be recovered.

    1. To be honest I can’t remember and I don’t have any APs to test with currently.

      You could reset as per the above then run dir flash: again to see whats listed.
