considering that password recoveru hasnot been disabled:

use:

username "recover"

password "recover"

without the ""

Then you have 30s to do a hard reset (disconnect power cable, then re connect it)

That's it!

Hi,

Yes, shirin is correct, after you power on the switch, you will ask to update the new password, then, ask again if you are going to enable the password recovery features, you need to enable it for future use.
