Information About Troubleshooting the Software Configuration
Software Failure on a Switch
Switch software can be corrupted during an upgrade by downloading the incorrect file to the switch, and by
deleting the image file. In all of these cases, the switch does not pass the power-on self-test (POST), and
there is no connectivity.Follow the steps described in the
section to recover from a software failure.
Lost or Forgotten Password on a Device
The default configuration for the device allows an end user with physical access to the device to recover from
a lost password by interrupting the boot process during power-on and by entering a new password. These
recovery procedures require that you have physical access to the device.
Note
On these devices, a system administrator can disable some of the functionality of this feature by allowing an
end user to reset a password only by agreeing to return to the default configuration. If you are an end user
trying to reset a password when password recovery has been disabled, a status message reminds you to return
to the default configuration during the recovery process.
