If I try to recover password like this description says

Step 1 Connect a terminal or PC with terminal-emulation software to the switch console port.

Step 2 Set the line speed on the emulation software to 9600 baud.

Step 3 Power off the switch. Reconnect the power cord to the switch and, within 15 seconds, press the Mode button while the System LED is still flashing green.

Base ethernet MAC Address: 00:0x:xx:xx:xx:xx

Xmodem file system is available.

The password-recovery mechanism is enabled.

The system has been interrupted prior to initializing the

flash filesystem. The following commands will initialize

the flash filesystem, and finish loading the operating

system software:

It sounds like you have AAA in your configuration. If the switch has connectivity to your AAA server, check the config and the AAA server config. If it does not have connectivity, you'll have to wait for the AAA timeout before it allows local authorization (assuming that is also configured correctly). If not, you'll need to add local authorization after AAA fails.

Hope that helps.

You are right, this switch has AAA settings and has no access to AAA server. It has no connection to anything

Then this is the reason why.

Thank you
