Matthew,
It may be that the Rx circuitry on the console port of your switch is fried - in that case, you're probably out of luck.
There is a slight possibility that you have configured no exec on your console port, causing it to not start a command interpreter when you hit Enter. Can you actually try to perform the password recovery procedure and see if the keyboard is accepted at least in the bootloader mode?
- Unplug the switch off from the mains.
- Press down the MODE button on the front panel.
- While keeping it pressed, plug the switch back to power. Do not release the button - keep it pressed.
- After roughly 10-15 seconds, the console should display a message that the boot process was interrupted, and suggest a number of commands to enter to continue booting. At that time, you may release the button.
- Enter the flash_init command if possible. If this works, you're lucky and just the configuration was screwed.
- Enter the load_helper command
- Enter the rename flash:config.text flash:config.old command
- Enter the boot command
If entering commands in the bootloader mode, do not use TAB, arrows or Ctrl-Key combinations because they are not supported, and will always cause a command to be unrecognized. If you make a typo, delete the whole line up to the typo, correct it, and type in the remainder of the command again.
Best regards,
Peter
